Five departments issued the management measures for step utilization of power batteries for new energy vehicles.

Cctv newsAccording to the news of Gongxin Micro-newspaper, in order to strengthen the cascade utilization management of power batteries for new energy vehicles, improve the comprehensive utilization level of resources and ensure the quality of battery products for cascade utilization, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, the Ministry of Ecology and Environment, the Ministry of Commerce and the General Administration of Market Supervision jointly formulated the Measures for the Administration of Cascade Utilization of Power Batteries for New Energy Vehicles (hereinafter referred to as the Measures).

The "Measures" propose to encourage echelon utilization enterprises to cooperate with enterprises such as new energy vehicle production, power battery production and recycling and dismantling of scrapped motor vehicles, strengthen information sharing, and use existing recycling channels to efficiently recycle used power batteries for echelon utilization. Encourage power battery manufacturers to participate in the recycling and cascade utilization of waste power batteries.

Article 6 of the "Measures" points out that the echelon utilization enterprises should meet the requirements of the "Industry Standard Conditions for Comprehensive Utilization of Waste Power Batteries of New Energy Vehicles" (Announcement No.59 of the Ministry of Industry and Information Technology, 2019). Encourage the use of advanced and applicable technology and equipment, and give priority to the step utilization of waste power batteries at the package (group) and module level. The disassembly of battery packs (groups) and modules conforms to the relevant requirements of the Disassembly Specification for Recycling and Disassembly of Vehicle Power Batteries (GB/T 33598).

Article 13 of the "Measures" points out that the design of echelon products should comprehensively consider factors such as electrical insulation, flame retardant, thermal management and battery management to ensure the reliability of echelon products; Adopt a structure and connection mode that is easy to maintain, disassemble and disassemble, so as to facilitate the disassembly, disassembly and recovery after scrapping.

Using mobile APP to spread obscene articles for profit was solved. The suspect taught himself to develop mobile phone applications.

  CCTV News:Not long ago, the Netan detachment of Zhoushan Public Security Bureau of Zhejiang Province and the Cultural Comprehensive Law Enforcement Detachment of Zhoushan Cultural Bureau cracked a case of spreading obscene articles for profit by using mobile APP, which was listed as a case supervised by the National Leading Group Office for Combating Pornography, and arrested Li, the producer of the mobile APP of Fast Fish Cloud Broadcasting, Yu, Shi and Ren, and found more than 7 million obscene video files in the mobile APP of Fast Fish Cloud Broadcasting.

  In July this year, Liu Haibo, a grass-roots grid member of Zhoushan New Town Management Committee, found in his daily visit that many people were watching obscene videos using a mobile APP called "Fast Fish Cloud Broadcasting", which aroused his vigilance.

  After mastering and fixing the relevant evidence, the Cultural Comprehensive Law Enforcement Detachment of Zhoushan Municipal Bureau of Culture immediately launched the joint disposal mechanism for eliminating pornography, provided relevant clues to the Netan Detachment of Zhoushan Public Security Bureau, and cooperated with the Netan Detachment to investigate related cases.

  Access to overseas obscene websites is hidden.

  After receiving the relevant clues, the Netan detachment of Zhoushan Public Security Bureau immediately filed an investigation. During the investigation, it was found that the "Fast Fish Cloud Broadcasting" APP was extremely confusing and concealed in the process of spreading obscene pornographic videos.

  The police investigation found that the main page of the "Fast Fish Cloud Broadcasting" App is no different from the normal film and television App. Users can watch a large number of legal film and television works as long as they install it, but when they click on the sub-pages such as classification and search on the page, obscene pornographic video pages will pop up on the mobile phone. By purchasing the registration code and registering as a member, you can browse and watch these obscene video contents.

  Gu Zhoutao, Deputy Team Leader of Netan Detachment of Zhoushan Public Security Bureau: "The criminal suspect made this mobile APP, and its communication route is mainly through his QQ group, WeChat circle of friends, or website. To watch obscene videos, you must first get an invitation code on your mobile phone and send a part of the invitation code to the card issuing website. "

  After careful investigation, the police found that most of the registered users of this mobile APP purchased the "registration code" from a place in Huanggang, Hubei Province, and there are more than 1,500 registered members from all over the country, and the actual owner and maintainer of this mobile App is Li, a native of Xuzhou, Jiangsu Province. Li made the "Fast Fish Cloud Broadcasting" App, rented the Internet data cloud to set up a server, and finally accessed more than a dozen overseas obscene websites and more than 7 million obscene video resources.

  Through further investigation, the police also found that 16 other people, such as Shimou from Yuyao, Ningbo and Renmou from Deqing, Huzhou, also bought apps from Li or purchased obscene video resources to access their own apps, and then spread them for profit. After mastering sufficient evidence, Zhoushan Public Security Bureau police rushed to Xuzhou, Jiangsu, Huanggang, Hubei, Yuyao, Zhejiang, Huzhou and other places, and successfully arrested suspects such as Li, Shi and Ren with the cooperation of local police.

  Self-taught mobile phone application development is involved in pornography and is in jail.

  Different from the previously uncovered cases of spreading obscene articles on the Internet, the case of "Fast Fish Cloud Broadcasting" spreading obscene articles for profit by using mobile App has the characteristics of fast spread, wide spread and large audience. The four people involved in "Fast Fish Cloud Broadcasting" arrested by the public security organs are all very young, and three of them are post-90 s. What is even more surprising is that Li, the developer of the mobile APP "Fast Fish Cloud Broadcasting", has only a first-year junior high school education.

  Gu Zhoutao, deputy detachment leader of the Netan detachment of Zhoushan Public Security Bureau, said that it is difficult to block obscene videos spread by the "Fast Fish Cloud Broadcasting" mobile APP.

  Gu Zhoutao, Deputy Team Leader of Netan Detachment of Zhoushan Public Security Bureau: "This software is very concealed. The cases encountered in the past spread through the cloud disk and are easily blocked by the public security organs. Connected through the mobile APP, it is very concealed and difficult to block, so these obscene video data quickly spread to the whole country. "

  The registration code used by registered members of this APP is also very cheap online. The registration code is divided into day card, month card, half-year card, year card, permanent card, etc. The online price of permanent card is 98 yuan, and the cheapest day card only needs 2 yuan. From March this year, the "Fast Fish Cloud Broadcasting" went online for only six months until the incident, tens of thousands of people across the country have registered as members, and the relevant personnel have illegally made more than 100,000 yuan.

  Because of his poor family, Li began to work after dropping out of school in the first grade of junior high school, and later taught himself the mobile APP method online. In the face of police interrogation, Li realized that his mistakes were irreparable. At present, four suspects have been transferred for prosecution.

"Spy Warfare, Deep Sea Sting" —— A good work with inside and outside.

  There was a time when the film and television circle commented that only middle-aged women and aunts were left watching TV dramas. This may not be wrong, because the themes of TV dramas at that stage were mostly mothers-in-law and parents, including court dramas. Therefore, it is normal that the types of TV dramas are narrow and the audience is naturally limited. Recently, the TV series "The Scare of the Deep Sea" is being broadcast. After watching several episodes that have been broadcast, I found that the previous conclusions may be outdated.

  Judging from what has been broadcast, I think the audience of this play may be wider. Young people chase stars, middle-aged people chase plots, and old people chase history, and they can all get their places.

  Story is the bone of film and television drama, and the character setting of the protagonist determines the direction of the story structure. The protagonist’s character setting in "Spy Wars: Deep Sea Stings" is quite interesting. The protagonist Chen Shan’s real identity is "touting" in Shanghai. Because he looks like Xiao Zhengguo, a special agent of the Kuomintang military system, he was forced to impersonate a special agent and enter the military system in Chongqing under the deadly threat of Japanese agents. However, Chen Shan never forgot that he was from China. In order to rescue my sister kidnapped by Japanese agents, I had to deal with Japanese agents. Chen Shan finally got in touch with the Communist Party of China (CPC) in Chongqing, under the influence of the national justice and the love and hatred between home and country. Therefore, Chen Shan has four identities in the play: natural Chen Shan, Japanese spy, Kuomintang military intelligence personnel, and underground workers of the Chinese Communist Party.

  This kind of character setting makes the story clues intertwined and the plot complicated, which increases the difficulty of scriptwriting. For example, Chen Shan, a character, had to complete the task assigned by the Japanese spy department in order to save his sister from Japanese spies, but he didn’t want to hurt his country and people. Chen Shan’s every action, in the words of Zhang Li, the heroine in the film, is like gambling. Keep the audience in the plot: what to do next? Zhang Li, as a member of the Chinese Communist Party who entered the military system, found Chen Shan strange and had doubts about Chen Shan. Even if Chen Shan helped her out of danger, she remained vigilant about Chen Shan’s true identity and true purpose. It is not Zhang Li’s choice to expose Chen Shan. It is a severe test for Zhang Li how to borrow Chen Shan and finally turn it into the Communist Party of China (CPC)’s overall anti-Japanese service while ensuring his own safety. As for Zhou Haichao, Xiao Zhengguo’s former colleague in the military system, there are also many clues in the play. Zhou Haichao has personal selfishness and ambition to make a fortune, and Xiao Zhengguo is his biggest obstacle. Coupled with Zhou Haichao’s own fatal weakness, when the fake Xiao Zhengguo returned to the military system, Zhou Haichao naturally regarded Chen Shan’s fake Xiao Zhengguo as the main object of prevention and suspicion

  In several episodes that have been broadcast, the writers and directors have explained the plots and clues in an orderly and calm way, without feeling messy, vague and blunt. The actor’s performance is also in place. Although the play uses voiceover, which is rare in film and television dramas, in order to express the special field of intelligence front, voiceover can play the role of making the finishing point and connecting the preceding with the following, and can also make the plot more clear and concise. At this point, the audience has reason to expect the fate of the characters in the play and the subsequent plot development.

  "Spy Warnings in the Deep Sea" is also one of the shows of film and television works for the seventieth anniversary of the founding of New China. However, for a long time, there has been a misunderstanding among some literary and art workers that works that promote the main theme are not effective. It seems that what is popular in the market can only be gag and crooked works. Literature and art should not be slaves of the market, and should not be covered with copper odor. Excellent literary and artistic works, it is best to be successful in thought and art, and to be welcomed in the market. " This truth is not complicated. Only when literary and artistic works are loved by the audience can the audience be educated.

  Judging from the part that has been broadcast, The Deep Sea Sting of Spy Wars has handled this issue well. War of Resistance against Japanese Aggression is a common theme in literary and artistic works. Historically, in order to invade and occupy China in modern times, Japan collected a lot of information about China from before the Sino-Japanese War of 1894-1895. We cannot overestimate the detail, depth and comprehensiveness of Japanese intelligence espionage in China. The wolf ambition of Japanese militarism is also evident from the thoroughness and sufficiency of its espionage work. This historical fact is integrated into the play, which makes the story thrilling, tense and dangerous, and it is often unexpected, ups and downs and reasonable, which can arouse the audience’s expectation.

  War of Resistance against Japanese Aggression is an arduous and complicated historical task for the Communist Party of China (CPC). Resolutely resisting Japan is the first principle. Under this principle, it is also necessary to obtain Japanese intelligence, which highlights the importance of Chen Shan. How to counter Chen Shan requires both courage and skill for the Chinese Communist Party’s intelligence system. In addition, during War of Resistance against Japanese Aggression, the Communist Party of China (CPC) had both cooperation and struggle with the Kuomintang. Therefore, "The Scare of the Deep Sea" can present the complexity of history to today’s audience through a special character and a story in a special environment. It should be said that the starting point is well grasped. The primary value judgment of every choice of the positive characters in the play is patriotism and national interests, which makes the tone and main line of the whole play reliably guaranteed.

  There is another feature of the play that gives me further suspense. The protagonist Chen Shan himself is from Shanghai. The first few episodes of the story took place in Shanghai, and there were many lines in Shanghai dialect and Shanghai accent in the play, which made me a Shanghainese sound very kind. Due to special historical reasons, Shanghai has always been a hot spot on the intelligence front in the modern history of China. All kinds of forces at home and abroad, without exception, regard Shanghai as an important place for obtaining and transferring information. Even during War of Resistance against Japanese Aggression, Shanghai was occupied by the Japanese, and it was no exception. Therefore, although the story is now transferred to Chongqing, the wartime capital of the Kuomintang, it remains to be seen whether the follow-up plot will return to Shanghai.

  Finally, I want to say that no matter what age you are, you should not regret chasing this drama. (Liu Yang)

The original tens of millions of online celebrity small groups are suspected of being arrested, and they will be jailed for 8 years and face huge fines because of the fighting fish incident.

Original title: Ten million online celebrity small groups are suspected of being arrested, and they will be imprisoned for 8 years and face huge fines due to the fighting fish incident.

As a well-known anchor of the platform for fighting fish, online celebrity Tuantuan is afraid of being sentenced to 6-8 years in prison for being suspected of participating in money laundering activities on the platform, and the amount involved is as high as 48 million, and about 11 people in the whole trade union have been arrested. In fact, before this, there was a warning that she had announced that she had stopped broadcasting because of "involuntary" and went online after the first stop, saying that she had to continue to stop broadcasting because of "involuntary". Although she did not disclose the specific reasons, she mentioned that she had experienced many bad things in the last month. She hasn’t been seen since it was announced in November last year.

Well-known gossip anchor cold wind also said during the live broadcast:

It is very likely that the small group will be eight years. Maybe the assistant of the small group will take five to six years, and her assistant has not come out yet. If the assistant has no income, it may be delayed. It seems that the problem of Xiao Tuan Tuan is still quite big.

However, these revelations have not been officially confirmed, and their authenticity is still difficult to verify for the time being.

The Betting Platform has been thoroughly investigated for money laundering before, and its owner, Li Shaojie, was arrested for opening a casino. Betta has various forms in this respect, such as opening casinos, money laundering and smuggling activities with northern Myanmar, and organizing activities by lottery in live broadcast rooms.

The most popular "card lottery" game is the most popular in the live broadcast rooms of major anchors. The form is that the audience spends money to buy props, gifts, open cards to participate in the lucky draw, and the anchor usually gives the bonus to the audience privately. Take the betta anchor "Jiujijiu Outdoor" as an example. He has more than 3 million fans on betta. By the time he was arrested, the live broadcast room had organized more than 4,200 lottery games, with more than 4.42 million people participating, and finally "attracted nearly 120 million yuan", which shows how violent it was!

In January 2021, the "Changsha Rural Death Squad" was selected as the top ten anchor of DouYu Platform. According to the Green Hornet, the "Changsha Country Death Squad" is the "biggest casino for fighting fish", with an annual flow of 177 million yuan and a daily flow of 13 million yuan. At 10 o’clock every night, the lucky draw activities suspected of gambling are started, and the public code "Ten-Point Economy Class" is also formed.

According to the news that China. com quoted the anchor of the platform, the Betting Platform may have been aware of the cash back of the anchor’s lottery, and 50% of the revenue from the anchor’s running water also goes directly to the platform. With the increasing business pressure, fighting fish or being driven by interests is "desperate", and the chaos of live broadcast reappears. This is also the reason why many anchors lost contact.

postscript

The above content is part of online news, so we should keep a rational and objective attitude until it is officially confirmed. At the same time, this incident also warned the live broadcast industry and the Internet platform that it is necessary to strengthen self-discipline and standardized management to avoid similar problems. For the majority of netizens, it is necessary to raise their awareness of self-prevention, stay away from illegal activities such as the Internet, and jointly maintain a healthy and harmonious network environment. Of course, we also expect relevant departments to give clear findings as soon as possible, so that the public can know the truth.

Investigation on mobile phone surfing of college students: over 40% surf the Internet for more than 5 hours every day.

  China Youth Network, Beijing, October 21st "It’s not that I’m not sleepy. I just want to wait. As for what? I don’t know, I just want to wait. "This passage has become the mantra of many college students. And this "wait", most of them are brushing their mobile phones. So, how long do college students surf the Internet on their mobile phones every day? What are you mainly doing? Are you worried about network security?

  Recently, China Youth Network Campus News Agency conducted a questionnaire survey among 1,220 college students around the country. The results show that more than 40% of students surf the Internet for more than 5 hours every day, and more than 80% of students surf the Internet mainly for social chat. Most students think that surfing the Internet by mobile phone makes mobile payment, information acquisition and social communication more convenient. Nearly 90% of students are worried about network security, and most students expect the network speed of 5G to be faster and more convenient for study and life.

  Over 40% of students surf the Internet on their mobile phones for more than 5 hours every day, and over 80% of students mainly chat socially.

  Wu Lin, a student of Sichuan Agricultural University, uses his mobile phone to surf the Internet every day for about 6 hours. "It has become my habit to brush my mobile phone when I wake up every day. Now surfing the Internet is a daily need. I feel that I don’t have much to do except surfing the Internet. I like chatting, watching news and playing games online when I have no classes. I can’t stop playing my mobile phone."

  Like Wu Lin, there are not a few college students who have the habit of surfing the Internet for a long time. According to a survey conducted by a reporter from China Youth Network, 41.56% of college students spend more than five hours on their mobile phones every day. When surfing the Internet, 83.93% of the students mainly chat socially, followed by consulting materials and listening to songs, accounting for 62.46% and 58.61% respectively.

  "I am deeply dependent on the Internet, partly because of my shortcomings in social skills." Joline, a student of Northwest Normal University, told reporters that she is introverted and unwilling to communicate face to face. She can express herself more directly and accurately online. She will keep a diary on the trumpet in Weibo, and what she is embarrassed to say in person can be expressed by WeChat. "Besides, I can also tell my story with strangers through Zhihu."

  The picture shows the proportion of college students’ mobile phone surfing behavior. China Youth Network reporter Li Huaxi cartography

  Mobile Internet access makes mobile payment, information acquisition and social communication more convenient.

  So what convenience does mobile Internet access bring to college students’ daily life? In the survey, China Youth Network reporter found that most of the students interviewed thought that surfing the Internet by mobile phone made mobile payment, information acquisition and social communication more convenient, accounting for 90.25%, 80.49% and 78.52% respectively.

  "Now you don’t have to bring cash when you go shopping. It’s really convenient to pay by QR code." Zhao Tingting, a student at Guilin University of Technology, said that it used to be troublesome to use cash for shopping. Now, with mobile payment, the mobile phone can scan the code to pay, which not only saves a lot of time, but also brings great convenience to life.

  Chen Yixin, a student at Chengdu University of Information Science and Technology, told reporters that after going to college, she often chats with her parents online. "Sometimes I use WeChat videos, and it is very convenient to contact them anytime and anywhere even if I don’t go home." She also said that now she mainly watches news through Weibo and news apps, so she can keep abreast of the latest hot events, which is very fast.

  The picture shows the proportion of convenience brought by mobile internet access to life. China Youth Network reporter Li Huaxi cartography

  Nearly 90% are worried about network security, and most students expect 5G network speed to be faster and study and life more convenient.

  Xie Wenyi is a student of Shandong University of Technology, and he attaches great importance to network security. "I have learned that bank card deposits may be stolen by clicking on the link to help bargain, which makes me very worried about network security." In order to avoid the disclosure of personal information, he will be more cautious when registering his account. He told reporters that many friends around him have fallen into the trap of online fraud, so they must strengthen their prevention.

  The results of this survey show that 88.03% of the respondents are as worried about network security as Xie Wenyi. In addition to network security issues, 5G has also become a hot topic this year. When talking about the expectation of the 5G era, 87.38% of the respondents hope that 5G will make the network speed faster, and secondly, it will make the study and life more convenient and the video quality clearer, accounting for 86.64% and 71.31% respectively.

  Hong Yumin studied in Hope College of Southwest Jiaotong University, and she needed to surf the Internet frequently for professional reasons. When talking about 5G, she said that 5G is a "good medicine" for architectural drawing. It doesn’t take a long time to download the software installation package, which greatly shortens the students’ drawing time. Compared with 4G, 5G is more stable and not easy to get stuck. When drawing, you don’t have to worry about network failure, which can guarantee the smooth birth of the work.

  The picture shows the proportion of college students’ expectations for 5 G. China Youth Network reporter Li Huaxi cartography

  Teachers in colleges and universities suggest that Internet surfing time should be arranged reasonably and network security protection should be done well.

  Yang Mei, an administrative teacher at School of Information Engineering, Sichuan Agricultural University, believes that college students spend more time on the Internet than study time. Although this has become a common phenomenon, students are advised to pay attention to study. "At present, many students will become very anxious when they leave their mobile phones. In fact, students will make good use of the Internet to arrange their free time and pay more attention to WeChat official account and online classes related to their majors or employment, which will be helpful for future postgraduate entrance examinations or job hunting."

  "Don’t easily click on pop-up web pages or unreliable advertising links shared by others, which are likely to contain viruses. When surfing the Internet in Internet cafes outside, don’t connect your USB flash drive, mobile phone and other things containing important personal information to your computer, which is easy to cause network security problems." At the same time, as the class teacher of the students, Yang Mei recommends students with poor self-control to use professional APP for entertainment time management, hoping that students can concentrate on their studies and focus on their studies.

  This semester, Fan Yingjie, a teacher of Marxism College of Chengdu University, asked students to strengthen self-discipline, stay away from the internet at least half a day to one day in class and at ordinary times, and learn to control themselves. She hopes that through these ways, students can understand that instead of constantly paying attention to other people’s lives through mobile phones, it is better to live their own lives and do their own things in a down-to-earth manner.

  Fan Yingjie also mentioned that regarding the issue of network security, the relevant state departments released a lot of warning case materials when promoting network security, hoping that students would learn more about it. "When using mobile phones or computers to surf the Internet, students should not randomly click unfamiliar links to avoid revealing personal information on the Internet, and try their best to do network security protection."

E-commerce problem: please merchants or please users?

Original receiver Tech studio

Wen | Rao Yan

Editor | Brother Cai

To do a good job in e-commerce platform, should we pay more attention to merchants or users?

This is a controversial topic, and it is also a problem that is deeply confused by major e-commerce platforms. It seems that there is no standard answer.

Some people think that e-commerce platforms should pay more attention to merchants, because merchants can directly bring benefits to the platform; Some people think that we should pay attention to users, because users are customers who pay for money, "God" and traffic.

Some people think that both users and merchants should pay attention to it, but as a platform, e-commerce will treat merchants and users differently from a strategic perspective or from a specific implementation level, and it will inevitably focus on it.

For a long time in the past, both Ali and JD.COM, as established e-commerce platforms, and Tik Tok and Aauto Quicker, as emerging live e-commerce platforms, have consistently put businesses at the strategic core.

Compared with pleasing users, these e-commerce platforms pay more attention to pleasing merchants. After all, merchants can bring advertising, commissions and other service fees to the platform, which is also an important part of the existence of e-commerce platforms.

However, in the last two years, this concept has undergone a major change, and e-commerce platforms have begun to pay more attention to users.

In 2023, Ma Yun set the theme of "returning to Taobao, returning to users and returning to the Internet" for Ali’s transformation. One of the three themes is returning to users, emphasizing the importance of users.

In fact, Ali paid more attention to merchants in his early years, and "valuing merchants and neglecting users" was even regarded as Ali’s own gene. But now, while regaining the low-price strategy, Ali emphasizes paying attention to users and interprets e-commerce with his own experience. More attention should be paid to the laws of users.

JD.COM has repeatedly emphasized the importance of users in the process of pushing forward the low-price strategy. On March 29th, Liu Qiangdong, the founder of JD.COM, issued a letter to all employees, announcing that the corporate culture of JD.COM has been upgraded, and the core values of JD.COM have been upgraded to: customer first, innovation, hard work, responsibility, gratitude and honesty. Customer first has been used and put in the first place.

As a rising star of e-commerce, Pinduoduo has emphasized the importance of users since its establishment. Both its simple and direct "10 billion subsidy" and its harsh "only refund" model show the fact that Pinduoduo cares more about users than merchants.

As the latter, Pinduoduo can snatch food from other e-commerce platforms and develop rapidly. Paying attention to users is undoubtedly one of the secrets, which is also the real practice of the idea of "turning capitalism upside down" put forward by the founder of Pinduoduo in his early years.

At the end of last year, Taobao and JD.COM also launched a "refund only" service; At the beginning of this year, Tik Tok e-commerce also launched a fast refund service after delivery, which is aimed at all small shop merchants in the Tik Tok platform; At about the same time, Aauto Quicker e-commerce also upgraded the refund function after merchants agreed to reject it.

At this point, "refund only" has become a standard in the e-commerce industry, which means that the e-commerce platform finally chooses to lean towards consumers in the balance of interests of merchants, brands and users, and the e-commerce platform competes for users again.

In fact, the essence of retail is to provide users with better goods at lower prices and better services. In this sense, the e-commerce platform attaches importance to users, which is not only a transformation, but also a return, or a subversion of traditional production relations.

-01-

How do merchants and users view e-commerce platforms?

Consumers and businesses have different views on how e-commerce should be done and what kind of e-commerce the market needs.

Wang Li is a middle-level manager of an Internet giant. In the past years, he has been advocating all kinds of luxury goods. Many salespeople of big brands are his "WeChat friends". The annual shopping expenses range from hundreds of thousands of yuan to hundreds of thousands of yuan.

However, in the last three years, Wang Li’s consumption concept has changed. He is no longer obsessed with big brands, but pays more attention to adaptability. He usually shops through e-commerce platforms. "The quality of fruits that are killed by e-commerce platforms in a limited time is not worse than that of boutique merchants.; Daily necessities can also be purchased on the e-commerce platform. "

"Some daily necessities don’t need to pursue quality too much, as long as they can meet the demand. As for whether it is a brand or not, it is not that important on which platform to buy it." Wang Li told "handset tech (ID: tingtontech)".

Like Wang Li, more and more consumers are no longer loyal to an e-commerce platform, but choose the products they need to buy on different e-commerce platforms. They choose according to their needs, instead of blindly pursuing quality, they pay more attention to cost performance.

So what kind of e-commerce platform are businesses more willing to settle in?

The ultimate pursuit of merchants is to maximize profits. Which e-commerce platform can make merchants realize greater benefits, merchants are willing to cooperate with which platform. However, it is not easy to achieve this goal, which requires the cooperation between merchants and platforms, involving advertising services, commissions, platform policies, platform logistics, and promotional activities.

Liu Ming, the head of the manufacturer of clothing, shoes and hats in Guangzhou, told Earphone Tech that he was more willing to settle in Taobao and Tmall in his early years, because Ali paid more attention to the support and protection of merchants, and the platform brand was well-known and the traffic was large. "But in recent years, the traffic of Taotian was not as good as before, and our income was also affected."

In recent years, Liu Ming has changed his strategy and adopted a multi-platform operation mode. According to the characteristics and differences of various e-commerce platforms, he has promoted different product lines and diversified price systems. At the same time, he has increased cooperation with live broadcast e-commerce companies such as Tik Tok and Aauto Quicker.

Feng Li, a small and medium-sized manufacturer of towels, recently told "Earphone Tech" that "we have cooperated with different e-commerce platforms, and went to stock through Pinduoduo and 1688, and mainly made brands in Tmall."

Feng Li said that although the profit margin of low-priced platforms is not high, the sales volume is good. Although the profit margin of quality products is high, the investment is also more. "For example, the cost of Tmall stores is much higher and the operating costs are relatively large."

Feng Li calculated that compared with other e-commerce platforms, the profit rate of towels on Pinduoduo was at least 2 points higher, because of a large number of orders. "We also broadcast live in Aauto Quicker, and the price is also very cheap, and the sales volume is not bad." Feng Li said that the main income for one year now comes from two platforms: Pinduoduo and Aauto Quicker.

For businesses, it will cost more to be a brand. In the current economic situation, large sales volume and low cost are the pursuit of all businesses, and they are also the common requirements of a large number of small and medium-sized businesses for e-commerce platforms.

In recent years, with the return of mass consumption to rationality, the sales of many high-premium brand products have declined. In order to save the market, some high-premium brands have begun to cut prices sharply.

This is also an important reason for the rapid rise of Pinduoduo and Aauto Quicker in the past two years. In a rational consumption channel, excessive pursuit of brand premium won’t work, and high cost-effective goods have a way out. The surge in sales of white-brand goods in the past two years is also this logic.

Should e-commerce please merchants or please consumers?

Should the e-commerce platform pay more attention to merchants or consumers? There seems to be no standard answer, but time and reality give the final answer.

As a veteran e-commerce, Ali paid more attention to merchants in his early years, and "emphasizing merchants and neglecting users" was also regarded as a major feature of Ali. Ali emphasized in his early years that "there should be no difficult business in the world".

In the early days of e-commerce, many merchants didn’t understand e-commerce and wouldn’t sell online. Taobao put forward such a concept in those years, but now the times are different and e-commerce has matured. The platform should not only focus on how merchants sell good goods, but should pay more attention to letting consumers buy good goods.

For a long time in the past, Taobao Tmall’s platform grew bigger and bigger, and its business developed faster and faster, but users did not feel better service.

Sometimes there is a contradiction between users and merchants. When merchants can’t solve users’ problems, the platform customer service either can’t contact or doesn’t solve the problems. The customer service efficiency is very low, and many users have complained about such problems.

In those years, during the annual promotion activities, users finally enjoyed some preferential prices, and the e-commerce platform also vigorously promoted preferential prices. However, what the end users felt was not real cheap, but various words and routines, and the algorithms were also very complicated. In order to enjoy the preferential prices, users had to meet various requirements.

What is even more unacceptable to consumers is that even if users place orders in this way, they finally find that it is not much cheaper. Moreover, the e-commerce platform has been playing in this way for many years until consumers are bored with it.

In 2023, just as Ali’s market value was once surpassed by Pinduoduo, Ali employees left messages on the intranet, bluntly saying that Taotian should "simply buy, simply return, less routines and more benefits", which spoke out the voices of many users and also showed that Ali began to realize the problem.

In fact, Taobao’s early positioning was similar to that of Pinduoduo, and it grew up with low prices and small and medium-sized businesses. Unfortunately, Ali later abandoned many small and medium-sized businesses on his own initiative.

A few years ago, Ali firmly believed that an era of consumption upgrading was coming. Therefore, Taobao constantly upgraded its brand, introduced a large number of brands to settle in, and the annual technical service fee and default bond of the store also increased, causing some small and medium-sized businesses with weak competitiveness to leave Taobao.

This wave even spread to AliExpress, a cross-border e-commerce platform owned by Ali at that time. Around 2016, AliExpress more aggressively promoted brand transformation, requiring merchants to have corporate qualifications and brand authorization, and comprehensively cleaned up individual sellers.

In this way, not only small and medium-sized businesses have left Taotian and AliExpress, but also users have begun to choose other e-commerce platforms. The impact on Ali is that the development of Taotian has slowed down, the traffic has been separated, and the frequency and retention time of users have become less and less.

About ten years ago, AliExpress had almost no China rivals in the cross-border e-commerce field at that time, and it was very convenient for merchants to sell goods. With one click, the product information on Taobao could be transported to AliExpress. However, the departure of small and medium-sized merchants made AliExpress develop slowly after its initial success. In the last two years, the cross-border e-commerce fire broke out, and AliExpress started early but caught up with a late episode.

When Ali realized all this, the Internet had already bid farewell to the high-growth era in the past and entered the moment with the theme of reducing costs and increasing efficiency. At this time, Ali had to face not only Pinduoduo, a rapidly rising opponent, but also the impact brought by live e-commerce on short video platforms, and the original advantages of Taobao and Tmall were weakening.

To this end, Ali launched the largest organizational change since its establishment in 2023, and then made personnel adjustments. Zhang Yong’s position as Chairman of the Board of Directors of the Group was handed over to Cai Chongxin, and the CEO position was taken over by Wu Yongming. The CEO of Taotian Group, the core e-commerce business, was also replaced at the end of last year.

Ma Yun thinks that the situation of Taotian Group is very serious, and asks Ali to return to Taobao, users and the Internet.

If Ali started to return to users after a long walk, then Pinduoduo, as a rising star, decided to put users first from the beginning.

Unlike Ali, who pays more attention to businesses, Pinduoduo cares more about users. Ali emphasizes "no hard business in the world", while Pinduoduo makes users feel that "there is no hard goods in the world".

In fact, low price is a universal demand. No matter the rich or the poor, there is a demand for "what they want" at an "affordable price", and Pinduoduo attracts people who are looking for high cost performance.

People in this group may spend a lot of money on an expensive brand-name watch or spend 9.9 yuan on a towel, and Wang Li is one of them.

When Pinduoduo was founded, data showed that about 90% of China adults had never drunk Starbucks, 1.3 billion people had never been abroad, and 1 billion people had never been on an airplane, and low-and middle-income people still accounted for the vast majority.

What Pinduoduo needs to do is matching, so that the right people can buy the right things in the right scene, which can not only provide the consumers in the sinking market with the right goods, but also provide the consumers in the first-and second-tier cities with the matching goods categories.

This is not a consumption downgrade, but a consumption classification. Pinduoduo’s approach also has its own unique business logic.

The founder of Pinduoduo once wrote an article called "Turn Capitalism upside down", which mentioned that as the ultimate representative of capitalism, the essence of insurance is that the poor spend money to buy a product that "seeks stability in an uncertain future" from the rich, so as to strengthen their ability to resist risks, and eventually wealth will flow from the poor to the rich.

The article puts forward a hypothesis, can the rich buy "insurance" from the poor in reverse, that is, buy a kind of stability, so that wealth can flow from the rich to the poor?

"Everyone’s wishes, their needs and plans at some point in the future are often much clearer than others. Moreover, this kind of everyone’s planning and willingness, as well as the individual’s certainty of a certain behavior, are often valuable to the supplier who meets the demand. It can reduce the uncertainty of organizational production and help achieve more effective allocation of resources and capital. "

Based on this concept, the article believes that if there is a platform that can get enough customers to buy a certain product, integrate the customers’ needs and send an order to the factory, the factory will sell the products to these customers at a price lower than the market price.

Moreover, because this order pays a certainty to the factory, the factory can reduce the risk of market research and forecasting the production direction of the market, and also reduce the inventory cost.

In a sense, this is a new type of relations of production, which was really realized by Pinduoduo later, and became the underlying logic of Pinduoduo.

Perhaps many people once resented Pinduoduo’s "cutting a knife", but they have to admit that Pinduoduo’s "reverse capitalism" has succeeded. In the past two years, while most Internet giants have experienced a trough, Pinduoduo has been growing substantially.

This is not so much a victory of the new e-commerce model as a victory of embracing users in the Internet age.

-03-

How does the e-commerce platform please users?

How should the e-commerce platform please users? The first is low price.

The essence of retail is to provide users with better goods at lower prices and better services. Low price is the big killer, and cheap is the last word, which is also the truth confirmed by the development of domestic e-commerce.

Domestic e-commerce has developed for so many years, and the competition has never stopped, and the means of competition are also varied. However, the most powerful means of competition has never changed, and it is still a price war.

On June 1st, 2019, Pinduoduo entered the "618 Promotion" for the first time in an all-round way, and announced that in the form of "10 billion yuan cash subsidy", joint brand merchants would make substantial profits on 10,000 items with the highest popularity in the whole network.

Compared with the subsidies of other e-commerce platforms with complicated algorithms, Pinduoduo’s tens of billions of subsidies are simple and straightforward, either directly subsidizing or directly reducing prices, and there is no need to make a bill or play "full reduction", which also makes Pinduoduo, which was originally dominant in the sinking market, win more shares and uses.

According to the data in the early years, during the period of June 18, 2019, the number of orders in Pinduoduo exceeded 1.08 billion, and GMV increased by over 300% year-on-year. Since then, the subsidy of 10 billion yuan has become a long-term strategy of Pinduoduo and a powerful means to attract users. By this means, Pinduoduo artificially created a price depression and snatched a large number of user orders from Tmall and JD.COM.

In fact, in the early years, Taobao also defeated offline retail by relying on low prices, and began the prosperity of e-commerce; JD.COM also defeated Dangdang, the dominant book e-commerce company at that time, and Suning, the leading retailer of traditional household appliances, through low prices, thus winning a relatively stable market position.

Only later, with the continuous development of Taobao and JD.COM, the advantage of low price was lost. Until 2023, these two platforms began to pay attention to low price again.

In fact, since 2023, almost all e-commerce platforms have launched low prices. Besides Taotian and JD.COM, there are also live e-commerce platforms such as Tik Tok and Aauto Quicker. Like Pinduoduo, e-commerce in Aauto Quicker is also based on the sinking market, and in 2023, it ushered in a rapid growth in performance.

In addition to low prices, another way for e-commerce platforms to please users is to improve service quality and improve user experience. Since 2023, almost all e-commerce platforms have been working hard to improve the user experience.

Ali determined the theme of returning to e-commerce and returning to users, and established the strategy of building a big amoy. Facing the future, Taotian has determined three directions of "innovation and innovation", upgrading new scenes, new ecology and new technologies, among which the first one is user priority.

At the end of 2023, after Ma Yun shouted "Ali will change", Liu Qiangdong also replied to employees’ comments on the company intranet that JD.COM must change, otherwise there is no way out. "I believe we will definitely get out of the trough. Anyone and any company will experience several peaks and valleys to achieve greatness. "

Xu Ran, CEO of JD.COM, also responded that JD.COM has made some progress in price competitiveness, platform ecological construction and supply chain advantages. While the number of merchants has further expanded, the increase in the number of users has also proved the optimization of platform ecological construction.

Xu Ran said, "In the long run, JD.COM will resolutely pursue the ultimate user experience to maintain its core competitive advantage".

When e-commerce platforms begin to pursue low prices and changes, they all begin to emphasize user experience, which also means that e-commerce companies are changing their business philosophy and paying more attention to users’ needs.

Why are a large number of industrial belt enterprises willing to dig deep into the white-brand track? When the business model is based on "maximizing the unit consumption benefit", businesses can provide consumers with the products that best meet their actual needs at the lowest cost and price, and thus survive and develop.

In the future industrial world, whoever controls consumers will control manufacturing. If you can’t directly connect with consumers, you can’t win consumers, and you are doomed to have no longer-term future.

This is the future of retail and the long-term doctrine of e-commerce.

In recent years, the development of China’s new energy automobile industry has achieved remarkable results, and an industrial system with complete structure and organic synergy has been steadily established, which has become an important force for stabilizing China’s economy and industry.

In the second half of 2023, under the orderly guidance of the National Development and Reform Commission’s Twenty Measures on Restoring and Expanding Consumption, Shandong Provincial Department of Commerce’s Plan of New Energy Vehicles Going to the Countryside in 2023 and other heavy policies, the automobile industry economy began to usher in recovery, and further tapping the consumption potential of new energy vehicles became one of the topics of economic development in the second half of the year.

As an important part of 30 new energy vehicles going to the countryside in Shandong Province in 2023, this autumn auto show brings together 27 new energy vehicle brands.

In this exhibition, the proportion of new energy vehicles continued to increase significantly, exceeding half of the overall display brands for the first time, and many new brands came to Qingdao for the first time. It is believed that the 22nd Qingdao International Automobile Industry Autumn Exhibition in 2023 and the Qingdao New Energy Vehicle Tour to the Countryside will surely become an important platform to promote the deep integration, exchanges and cooperation between China and the world automobile industry, and contribute new strength to the smooth operation of the economy and the revitalization of consumption. "

This activity is the launching ceremony of the first activity of new energy vehicles going to the countryside in 16 cities in Shandong Province. Taking this as the opening ceremony, it will guide the new energy vehicle enterprises in the city to seize the opportunity of national new energy vehicles going to the countryside, promote new energy vehicles to better enter thousands of villages and thousands of households, help the country’s "double carbon strategy", promote rural revitalization and construction, boost consumer confidence, and form a strong atmosphere of industrial development and stimulating consumption to promote each other.

Regarding the epidemic, Zhong Nanshan has 12 latest judgments.

  At present, the situation of epidemic prevention and control in China continues to improve, and foreign epidemics spread rapidly. "External defense input and internal defense rebound" has become the focus of epidemic prevention and control in China. Can I take off my mask now? How contagious are asymptomatic infected people and relapsing patients? Will pets spread viruses? Recently, Zhong Nanshan, an academician of China Academy of Engineering, responded to the hot issues of epidemic prevention and control.

  It’s not time to take off the mask yet.

  Zhong Nanshan:At present, the situation at home and abroad is very different. China has entered the second stage of the epidemic because of its decisive measures, while other major countries are still in the first stage of the outbreak and are still climbing up. This means that the probability of human-to-human transmission is very high, and the number of confirmed cases increases very quickly.Wearing a mask is still an important means of self-protection, but it is not necessary to wear it in areas where the epidemic situation is not serious, places with few people or open spaces.

  Wuhan has passed the customs, but there is still the next pass.

  Zhong Nanshan:After the outbreak, the central government took decisive measures to control Wuhan’s urban traffic, and it was very successful to take measures to prevent and treat it in other places. In the history of epidemic prevention and control, this is also a feat. However, there are still two tests: one is how to prevent and control while returning to work, and the other is the "external defense input" barrier.At present, foreign epidemic situation is still at the peak, and some coastal cities in China, which have close communication with foreign countries, are easily "involved", and then some epidemic situations occur.It can be said that the next "pass" of Wuhan is also the "pass" of the whole country, and it needs to pass through various prevention and control measures.

  3. It is very unlikely that foreign imports will cause a second outbreak in China.

  Zhong Nanshan:There are actually two questions about whether the overseas epidemic will cause a second outbreak of the domestic epidemic: first, whether the imported cases have spread, and second, whether they will break out in the process of spreading. The risk of transmission of imported cases definitely exists, especially cases with positive nucleic acid test or symptoms of infection, which are highly contagious and will cause virus transmission. At present, the mass prevention and control in China has been sinking into the community, and community residents have a strong sense of self-protection, such as wearing masks and keeping a distance from others. Once someone has symptoms such as fever, he can report or accept diagnosis quickly, and then isolate.On the whole, the risk of community transmission certainly exists, but the probability of the second wave of outbreaks in China is very small.

  It is too early to talk about the "turning point" of the global epidemic.

  Zhong Nanshan:Globally, the original "epicenter" of the epidemic was in Europe, especially Spain and Italy, and now it also includes Germany, France and Britain.The biggest problem at present is the United States. In the past week, the number of confirmed cases in the United States has increased at a rate of 10,000 to 20,000 per day. It is too early to predict when the global epidemic will have an "inflection point".It can be said that whether there can be an "inflection point" mainly depends on whether governments can intervene strongly. There are many unpredictable factors in other countries. According to the current situation, I am afraid it will take another two weeks.

  5. The proportion of asymptomatic infected people in China will not be large.

  Zhong Nanshan:Asymptomatic infected people do not appear out of thin air, but usually appear in two groups: first, people who have not shown symptoms for the time being but may have been infected in areas with relatively serious epidemics; The other is the close contacts of the confirmed cases, and their proportion is relatively small. Asymptomatic infected people also have two concepts. One is that they have no symptoms at first, but then they will gradually develop into symptoms. Such patients are definitely contagious; The other is that during a long observation, there is no symptom all the time, but the nucleic acid test is positive. We are studying the infectivity of such patients.However, according to the characteristics of Covid-19, once symptoms appear, it is more contagious, so it is correct to isolate asymptomatic infected people for observation.

  6. Most patients with relapse are not contagious.

  Zhong Nanshan:Generally speaking, most patients with relapse are not contagious. Most of the so-called multiple positives are fragments of nucleic acid, not the virus itself.We need to pay attention to two situations. The first is whether the patient has a relapse. If the patient produces strong antibodies, he will not be infected again. As for whether patients with relapsing yang will be transmitted to others, it needs specific analysis. Generally speaking, nucleic acid fragments are not contagious. Some scholars have cultivated throat swabs and secretions of patients with relapsing yang, but they have not cultivated viruses. The second situation is that patients have many basic diseases, but their symptoms have improved and they have not fully recovered. These patients cannot rule out infectivity.

  7. There is not enough evidence of "influenza" in COVID-19.

  Zhong Nanshan:At present, there is not enough evidence of COVID-19’s "influenza".Unless there is such a rule in virus transmission: its infectivity is still strong, but the mortality rate is getting lower and lower. In this case, it is possible to exist for a long time. We now need to make long-term observation and master sufficient data and cases before we can draw such a view. Under the present circumstances, I don’t think this prediction will come true.

  8. It is too early to draw conclusions about animal-to-animal transmission.

  Zhong Nanshan:It remains to be seen whether some animals such as dogs, cats and tigers are positive for nucleic acid detection, which is caused by pollution or infection. Some animals originally carry some viruses, which may not be symptomatic or contagious.It is too early to conclude that Covid-19 in these animals can infect both humans and animals, and both can cause diseases.

  9. Some effective drugs have been found, but there is no specific drug yet.

  Zhong Nanshan:Some drugs we are testing now (such as chloroquine phosphate) are definitely effective. We are summarizing them and will announce them soon. There are also some Chinese medicines (such as Lianhua Qingwen), which we have not only done in vitro experiments, but also found in P3 laboratory (the third-level laboratory of biosafety protection) that their antiviral effect is not strong, but their anti-inflammatory performance is outstanding, and the relevant experimental results will be published soon. In addition, there is Xuebijing, a traditional Chinese medicine. Its main components include safflower, salvia miltiorrhiza, radix paeoniae rubra, etc. It is used to promote blood circulation and remove blood stasis, but it is also effective in the treatment of severe patients. We are summarizing the situation of these drugs.

  10. The vaccine will not be on the market soon, and the vaccination depends on the situation.

  Zhong Nanshan:Vaccine is very important to really end the epidemic. Now all countries are developing it at the fastest speed, but I don’t think it can be made in three or four months. In addition, according to the experience of fighting SARS, removing the intermediate host can also block the spread of the epidemic. At present, we are not clear about the transmission chain in Covid-19, and it is also important to cut it off after it is clear.Put all your hopes on the vaccine, and all other methods are negative. Moreover, after the vaccine comes out, it is impossible to be perfect at once. The susceptible population can be vaccinated, but it is not necessary for everyone to be vaccinated.

  11. Group immunization is the most negative practice.

  Zhong Nanshan:The most negative way to deal with the epidemic is the so-called "group immunity", which was the idea more than 100 years ago.At that time, human beings had no choice but to let the virus infect them, and those who survived the infection naturally got antibodies. I don’t agree to deal with Covid-19 in this way again. In the past 100 years, mankind has made great progress, and there are many ways to prevent it, so there is no need to use natural immunity or group immunity.

  12. The most worth sharing experience of the "epidemic" in China War is execution.

  Zhong Nanshan:China War "epidemic" mainly took two measures: first, blocked the outbreak area and blocked the spread; The second is grassroots group defense and group governance. Now there are two core points of prevention and control: one is to keep a distance, and the other is to wear a mask.

  So,China’s most shareable experience is execution.. The medical level and technical strength of many countries are much higher than that of our country. The reason why we were caught off guard in the face of the epidemic was because we were not prepared mentally and did not take decisive measures, which led to the infection of many front-line medical personnel. Once this line of defense collapses, it is easy to get out of control.

What is the correct posture for charging a mobile phone? Please keep this instruction.

  The second stand

  Many people find that after a few days of use, the mobile phone battery charges faster and faster, but the standby time is getting shorter and shorter. In order to make their mobile phone batteries more durable, many people choose to turn to the internet and follow the tips on how to extend the battery life. But you know what? Many online charging methods are wrong, and you have been cheated for so many years.

  Should the battery be completely exhausted before charging?

  No way! "Deep discharge" will damage the battery.

  There used to be a saying that the battery has a memory function, and you must wait until the battery of the mobile phone is completely exhausted before charging it to 100%, otherwise the battery will "remember" the proportion that needs to be charged, so that it needs to be charged before the battery is used up, and the charging will not be full.

  "Now smartphones use lithium-ion batteries, and the technology and structure of lithium batteries have undergone tremendous changes. It is wrong to recharge the mobile phone battery after it is completely exhausted." Wang Yonggang, a leading enterprise of new energy power battery and R&D engineer of Tianneng lithium battery, told the Science and Technology Daily reporter that the so-called "deep discharge" when the battery is completely exhausted may have an irreversible impact on the internal material structure of the battery and shorten the battery life.

  When charging, positive lithium ions "jump" into the electrolyte from the positive electrode, "climb" through the winding holes in the diaphragm, "swim" to the negative electrode, and combine with the electrons running from the positive electrode early; The opposite is true when discharging. Dr. Zhang Hua, who graduated from the Department of Materials Science and Engineering at the University of California, Los Angeles, made an analogy: whether it is discharging or charging, lithium ions have to get away from the original structure, which is a bit like carrying a bunch of things from one room to another. Therefore, the understanding of battery life should be based on the understanding of battery structure.

  That is to say, in the process of charging and discharging, the less lithium ions participate in the movement every time, the less damage to the structure; The slower the lithium ion running every time, the less damage to the structure. If the lithium ion runs almost, it is necessary to "deeply discharge" and continue to extract lithium ion from it, which will damage the battery.

  Do you want to end charging immediately when the battery is full?

  No need! Batteries have "overcharge protection"

  When charging a mobile phone, Netcom should immediately stop charging when the battery is charged to 100%, otherwise it will damage the battery life.

  In this regard, Wang Yonggang said, don’t worry too much. Lithium batteries are generally equipped with "overcharge protection". When the battery is almost full, it will automatically switch to trickle charging, that is, the charging is very slow and the current is very small. When the battery is fully charged, it will automatically cut off the power and will not continue to overcharge, so it will not have much impact if it is rushed to 100% at one time.

  Many people like to charge their mobile phones overnight before going to bed. In this regard, Wang Yonggang said that turning on their mobile phones at night will also cause power loss, and how much power is consumed, the charger will continue to charge the mobile phones with small current. "But such a long cycle will have a certain impact on battery life."

  Will sporadic charging damage the battery?

  Wrong! "Shallow charge and shallow discharge" is good for batteries.

  "Generally, the life of a lithium-ion battery can reach hundreds of charge and discharge cycles. The charge and discharge cycle here refers to the process of using up the electricity and then recharging it, rather than plugging the battery into a charger and then unplugging it once." Wang Yonggang said that "shallow charging and shallow discharging" of lithium-ion batteries, that is, sporadic charging, has little influence on the structure of anode and cathode materials, but will not affect the service life. "So, we usually emphasize that the charging and discharging of lithium-ion batteries should be shallow, and don’t challenge the ‘ Limit ’ 。” Zhang Hua said.

  These practices also affect battery life.

  Charging different models of mobile phones with non-original charger has its own matching charger. Using non-original charger may have an irreversible impact on battery performance due to the large current of the charger used.

  Making phone calls, playing games and watching videos while charging are all high current consumption. The current provided by the charger is less than the current consumed by the mobile phone, so it is necessary to output current from the battery while using the mobile phone while charging. That is to say, at this time, the battery is not charging, but discharging, and even the battery capacity will be "exhausted" quickly. The life of lithium battery is closely related to the number of charge and discharge cycles. When using the mobile phone while charging, the battery will switch between charge and discharge rapidly, which will affect the service life of the battery.

  When the mobile phone is placed in a high and low temperature environment, due to the instability of the electrodes in the electrolyte, the two electrodes of the battery will react chemically every time they are charged and discharged, and then the active substances will be consumed, and the chemical energy converted into electric energy will be reduced, and the battery capacity will be reduced. If the ambient temperature is too high, it will accelerate the chemical reaction and "self-discharge" of the battery and reduce the battery capacity; The low temperature below zero will also have a negative impact on the battery structure, even permanent damage.
