Sino-US tariffs welcome new news.

　　Late at night on December 26th, Beijing time, the Office of the US Trade Representative announced that it would further extend the 301-clause tariff exemption period for 352 imported goods from China and 77 imported goods from China related to epidemic prevention in COVID-19, from December 31st this year to May 31st, 2024.

　　Huawei successfully screened the screen today! On December 26th, the M9, the most expensive model of Huawei, went on the market, with a price of 469,800 yuan and a longest battery life of over 1,400 kilometers. Huawei Yu Chengdong said, "The M9 is the best SUV within 10 million yuan". He also said that the booking volume of M9 has exceeded 54,000. In addition, the poster released by Huawei on the evening of 26th showed that the two-hour listing of M9 (generally referring to reservation and no refund of deposit) exceeded 10,000 vehicles.

　　Look at the detailed report!

　　The Office of the United States Trade Representative announced that

　　On December 26th, local time, the Office of the US Trade Representative announced that it would further extend the 301-clause tariff exemption period for 352 imported goods from China and 77 imported goods from China related to epidemic prevention in COVID-19, from December 31st this year to May 31st, 2024.

　　Prior to this, on September 6th, the Office of the US Trade Representative also announced that it would further extend the 301 tariff exemption period for 352 imported goods from China and 77 imported goods from China related to epidemic prevention in COVID-19, and the period would be extended from September 30th to December 31st this year. On September 7th, China’s Foreign Ministry spokesperson Mao Ning said that as a matter of principle, we have always opposed the fight against tariff war, thinking that there is no winner in tariff war. The unilateral imposition of tariffs by the United States on China violates WTO rules, which is unfavorable to China, the United States and the world.

　　According to previous media reports, during Trump’s administration, he invoked Section 301 (commonly known as Section 301 of the US Trade Act of 1974) in the name of "national security" to impose tariffs on China’s imported goods. During the Trump administration, there were more than 2,200 goods exempted from tariffs, of which 549 products were extended for one year, but all exemptions expired at the end of 2020. In October, 2021, the Office of the United States Trade Representative announced that it planned to re-exempt 549 imported goods from China, and solicited public opinions on this. After a lapse of nearly half a year, the Office of the US Trade Representative issued a statement on March 23, confirming 352 of the 549 imported goods from China that were to be exempted from tariffs again. This tariff exemption period has been extended many times so far.

　　In March 2022, Shu Jueting, spokesperson of the Ministry of Commerce, said at the press conference that China noticed that on March 23, the Office of the US Trade Representative announced that it would resume exempting 352 items of goods imported from China from additional tariffs, which would help the normal trade of related products. China has always believed that the unilateral tariff increase measures of the United States are unfavorable to China, the United States and the world. Under the current situation that inflation continues to rise and global economic recovery is facing challenges, it is hoped that the United States will cancel all tariffs on China as soon as possible from the fundamental interests of consumers and producers in China and the United States, and push bilateral economic and trade relations back to normal track as soon as possible.

　　The M9 in Wenjie is selling like hot cakes.

　　On December 26th, Yu Chengdong, managing director of Huawei, CEO of BG, and chairman of BU, a smart car solution, officially released the M9 at the press conference of the world of inquiry and the whole scene of Huawei in winter, with the price starting from 469,800 yuan. Yu Chengdong said, "The M9 is the best SUV within 10 million yuan".

　　Wenjie M9 has launched four models with extended range and pure electric power, and the price range is 469,800 ~ 569,800 yuan, which is the most expensive model of Huawei at present. Among them, the extended range Max version is 469,800 yuan, the pure electric Max version is 509,800 yuan, the extended range Ultra version is 529,800 yuan, and the pure electric Ultra version is 569,800 yuan.

　　Yu Chengdong said that the order for the M9 has reached 54,000, and the first batch of new cars will be delivered on January 26th, 2024, and mass delivery will be started on February 26th. In addition, the poster released by Huawei on the evening of 26th showed that the two-hour listing of M9 (generally referring to reservation and no refund of deposit) exceeded 10,000 vehicles.

　　With the launch of new cars, there are three models under the brand of Wenjie: M5, M7 and M9. Together with the Zhijie S7, which cooperated with Chery not long ago, Huawei HarmonyOS Zhixing currently has two brands, namely Wenjie and Zhijie, and four models are on sale. In the future, Huawei will also work with BAIC andCooperate with new "Jie" generation brands and new models.

　　It is understood that intelligent car selection is the deepest cooperation mode between Huawei and automobile companies. Huawei not only provides key technologies such as intelligence, but also deeply participates in product definition and development, and also opens its own terminal channels to help sell cars. Previously, Huawei upgraded the smart car selection mode to HarmonyOS Zhixing.

　　It is the first partner of Huawei HarmonyOS Zhixing, and released the first intelligent car selection product in April 2021. In 2022, the sales volume of the brand series products created by both parties reached 75,000, which was once the fastest growing in China.Brand. However, in the first half of this year, the world encountered Waterloo, and the monthly sales volume once fell to more than 3,000 vehicles. Until three months ago, the listing of the new M7 in Wenjie achieved unexpected success, with orders exceeding 100,000 vehicles in just over two months. In order to deliver the model in time, the factory that produced the model invested more than 3,000 workers in two shifts, and delivered more than 10,000 single models in October and November for two consecutive months. Officials expect that the delivery of 23,000 vehicles will be completed in December, and the monthly delivery will exceed 30,000 vehicles next year.

　　He Liyang, president of Automobile Co., Ltd., said at the press conference on December 26th that Cyrus’ factory in Chongqing is stepping up production and has started the production mode of two shifts a day. He revealed that up to now, the number of new M7 cars in the world has exceeded 120,000, of which more than 60% users choose the smart driving version, and the monthly delivery capacity will reach 30,000 from January next year.

　　According to Blue Whale Financial News, it was learned from insiders close to Huawei that AITO will launch the new M5 in the first half of next year, and the brand-new M8 between M7 and M9 will also be launched in the second half of next year.

　　A-share "Huawei" want to be embarrassed again?

　　In the secondary market, this year,Concept stocks have been active repeatedly. Although they have been adjusted with the broader market recently, the Wind index still rose by more than 11% during the year, significantly outperforming the broader market index. In terms of individual stocks,The increase during the year exceeded 440%., Cyrus rose by more than 100%,、Wait for the increase to exceed 40%.

　　Recently, Huawei Technologies Co., Ltd. applied for registration of "Zunjie" and "Qingjie" trademarks, which are internationally classified as means of transport and scientific instruments, and the current trademark status is awaiting substantive examination. Previously, Huawei had applied for a series of trademarks related to the world, including Wen, Zhi, Yong, Hui, Zhu, Ao, Zhi and Yi. Not surprisingly, most of these "Jie" trademarks are prepared for HarmonyOS Zhixing Ecological Alliance. The above news once triggered a rise in concept stocks.

　　Recently, it was pointed out that Huawei vigorously laid out its automobile business, and the three models enabled automobile enterprises to build and sell good cars from simple to deep. Since 2023, the automobile business map has accelerated. Under the background of the rapid development of smart car industry, Huawei is expected to rise with the advantages of core technology, ecology, brand and channels. It is suggested to pay attention to the cooperative car enterprises in Huawei’s automobile industry chain and the core manufacturers in related fields such as intelligent driving, intelligent cockpit, three-electric system and traditional parts.

　　HuaxinIt is also indicated that the M9 is fully ahead in terms of safety, maneuverability and intelligence, and it is expected to become a new generation of explosive models, which will drive the flexibility of supply chain enterprises. It is suggested to focus on supply chain investment opportunities.He also said that he is optimistic about Huawei’s automobile industry chain.

　　Guosheng recently pointed out that the M9 in the world is expected to become another explosion of Huawei’s intelligent selection system, and it continues to verify that Huawei’s intelligent selection and empowerment car companies bring high growth. Continue to be optimistic about Huawei’s smart car industry chain. Smart car is a subdivision track with clear competition pattern and excellent medium-term logic. Considering Huawei’s industry-leading effects in autonomous driving, intelligent cockpit and intelligent safety, Huawei’s cooperative ecology is expected to enhance its product strength in the environment of intensified competition in the whole machine factory, and companies related to the industrial chain are expected to benefit from the development dividend of domestic smart cars by relying on ecological advantages, forming a pre-paid card position. At the same time, it is necessary to pay attention to the industrial changes brought by technology leaders, and autonomous driving is expected to accelerate its landing, forming an overall opportunity for the industry.

The P70 mobile phone was not released, but Huawei brought the "new" intellectual S7 and the first laptop MateBook X Pro equipped with Pangu model.

On April 11th, Huawei HarmonyOS Ecological Spring Communication Meeting was held online. Yu Chengdong, managing director of Huawei, CEO of BG, and chairman of BU, a smart car solution, revealed the latest sales data of HarmonyOS Zhixing at the press conference. The number of new M7 was 174,000 in seven months, and the cumulative number exceeded 70,000 in three months.

Xinzhijie S7 launches Huawei Visual Intelligent Driving HUAWEI ADS Scheme.

Zhijie is a smart car jointly built by Huawei and Chery. This time, it’s a new intellectual S7 based on the old S7. There are five products in Zhijie S7 released by Huanxin this time, namely Zhijie S7 Pro, Zhijie S7 Max, Zhijie S7 Max+, Zhijie S7 Max RS and Zhijie S7 Ultra. The price starts at 249,800 yuan.

This time, Huawei launched the basic version of HUAWEI ADS, and Zhijie S7 Pro will be equipped with this pure vision solution for the first time.

There are two schemes of automatic driving: lidar and pure vision, and there has been a debate in the industry about the advantages and disadvantages of the two schemes. Huawei used lidar scheme before, and this time it launched a pure vision scheme.

According to Huawei, visual intelligent driving does not rely on lidar and high-precision maps, which can realize "quick and easy opening of national high-speed cities and easy stopping of intelligent parking". Yu Chengdong also said at the press conference that Huawei’s pure vision scheme is better than Tesla’s posture experience. Tesla mainly adopts visual driving scheme.

In terms of battery life and charging efficiency, Zhijie S7 is fully equipped with Huawei Whale 800V high-voltage battery platform, with a minimum power consumption of 12.4kWh per 100 kilometers and a longest cruising range of 855km.

In the field of intelligent cockpit, the Super Desktop 2.0 of HarmonyOS 4 system supports the full boarding of mobile phone applications, and HUAWEI MagLink can expand the screen for the back row. In addition, in-vehicle smart assistant Xiaoyi will be connected to Huawei Pangu model in May.

The old Zhijie S7 was released in November, 2023, positioning a smart car with high energy and large space, with four configurations, with a pre-sale price of 258,000 yuan. However, the sales volume after listing and delivery is not very ideal. At one time, there were network rumors that Chery did not actively cooperate with Huawei in the production of Zhijie S7, and only allocated a small amount of production capacity to Zhijie S7, with a daily output of only a few dozen vehicles, which led to a large number of orders that Zhijie S7 could not deliver. However, Jin Yibo, a spokesman for Chery, responded to the The Paper reporter that the online rumors were not true, the cooperation between the two sides was smooth, and the resignation of senior executives was not due to the cooperation project. According to public data, the cumulative sales volume of Zhijie S7 is 2,297 units in the three months since its listing.

However, Huawei has always been good at rejuvenating old cars. At the beginning, it asked the old M7 models to sell well after rejuvenation. Can the new intellectual S7 replicate the brilliance of the new intellectual M7?

Chery has also made improvements in response to the delivery problem that was previously spit out. Yin Tongyue, Chairman of Chery Group, said at the communication meeting that Zhijie is Chery’s first priority strategic project, and an independent brand division has been established, led by the person in charge of R&D and manufacturing. The intellectual community has an exclusive manufacturing industrial park and special resources investment guarantee. Yu Chengdong said that Zhijie S7 got off the assembly line one car a minute, and now it has started mass delivery.

In addition, the price of Xinzhijie S7 has also been adjusted to make it more competitive. The latest consumer who buys Zhijie S7 will enjoy the rejuvenation rights worth 30,000 yuan, and the old owner will enjoy the owner care worth 13,000 yuan, including 10,000 yuan of cash-filled red envelopes. After this operation, Xinzhijie S7 and Xiaomi SU7 collided head-on in price.

Of course, we will often do what we are good at, and then Huawei will issue an upgraded M5. Yu Chengdong revealed that the new M5 will be released on April 23rd, 2024.

Huawei MateBook X Pro released, equipped with Pangu model.

Huawei also released Huawei MateBook X Pro, the first notebook computer equipped with Pangu model. This 14-inch notebook computer takes a thin route and weighs only 980 grams, but with the blessing of a large model, it can be more intelligent.

According to reports, the first application of Huawei Pangu model, AI summary function can quickly and accurately extract key information from text, audio and video content, which can help users quickly and accurately filter out valuable content from massive information, thus helping users to master the main points of the meeting more efficiently.

Huawei MateBook X Pro is also equipped with Huawei’s AI space function for the first time. Through the AI space, users can directly access rich AI applications with one click, and support more than 100+ agents. It is a one-stop AI capability aggregation portal, which can make code programming, PPT production, paper reading and typesetting, collection of learning materials, video picture creation, travel planning and other scenes more efficient and convenient.

In addition, the star flash version of Huawei wireless mouse was released together with Huawei MateBook X Pro. The mouse is equipped with star flash wireless communication technology and cooperates with adaptive frequency hopping algorithm. Compared with the previous generation of Huawei wireless mouse, the anti-interference ability is improved by 4 times+,and the complex environment is more stable. Huawei MateBook X Pro’s new products start at 11199 yuan.

　　Why is the balance insufficient?

　　After investigation, there were more than 490 pieces of information during the period from September 14, 2019 to October 26, 2019, all of which were "expenditures". The column of "transaction type" was mainly displayed as "quick" and "consumption", with the lowest amount in 1 yuan and the highest amount in 1000 yuan.

　　Where did the savings go?

　　Mr. Zeng said that although Ermei deleted all the transaction records in the short video software and the game, she inquired about Alipay payment records, of which about 50,000 yuan was used for "rewarding" and about 20,000 yuan was used for buying equipment in the game.

　　Why are you spending like crazy?

　　The girl told so-and-so that every recharge is voluntary and rewarding the anchor is voluntary. The reason for frequent recharge is: First, because it can be upgraded, there is pride in front of students who also play this game; Second, because you buy "skin" by recharging, you can have many beautiful clothes.

　　In order to upgrade the game and reward the anchor, a 13-year-old girl from Zigong, Sichuan, recharged a short video platform, "Fifth Personality" and "Mini World" in China for more than 490 times in 43 days, and stopped her "crazy games" … …

　　His mother, Wen Qingshu, said that this deposit of more than 70,000 yuan is the only savings saved by the family in the past two years. When this happened, she blamed herself, saying that she didn’t discipline her children well on weekdays. At the same time, she also hopes that the platform can be refunded.

　　On November 10th, Wen Qingshu reported to the local police station in Fushun, Zigong for help. A few days ago, the Chengdu Business Daily-Red Star journalist also contacted the short video platform involved, and the other party responded that if the minor rewards without the consent of the guardian, once verified, the platform will give a full refund.

　　Insufficient balance

　　Mother’s bank withdrew more than 70,000 yuan and her savings were "missing"

　　At 3 o’clock on the afternoon of November 10th, Wen Qingshu, 51, from Fushun County, Zigong City, went to the bank to withdraw money to pay the rent. The counter staff told her that "the balance of your card is insufficient", which surprised her: the card clearly has more than 70,000 yuan. How could it be missing?

　　Through further inquiry, it was found that the savings card was artificially bound to Alipay, and almost all of the 74,242.58 yuan in the card was spent through Alipay, leaving only 0.46 yuan.

　　Wen Qingshu and her husband have three daughters. The eldest daughter has worked, and the second and third daughters are still in primary school. For many years, her husband worked in other places, and Wen Qingshu spent most of her time at home taking care of her two daughters’ diet and daily life. Wen Qingshu’s education level is limited, and she has little contact with new things. She has never used online payment methods such as online banking, Alipay and WeChat. For the sake of economy, even the simplest bank card SMS prompt function has not been opened.

　　So, who moved the savings deposit at home? Wen Qingshu hurriedly called her eldest daughter and asked her to come back and find out.

　　Checklist

　　More than 490 expenditure records　Once at most, 1000 yuan.

　　Knowing that the money in her mother’s bank card was "missing", the eldest daughter called her husband to the lady and hurried back to Fushun from Zigong City. With the help of her daughter and son-in-law, Wen Qingshu printed the running list in the bank and then took it home to check it carefully.

　　After consulting, the running list information from September 14, 2019 to October 26, 2019 is really surprising.

　　According to the inventory records, there are about 508 pieces of transaction information in the whole year, among which only more than 10 pieces of transaction information were recorded from November 11, 2018 to September 7, 2019, while more than 490 pieces of information were recorded from September 14, 2019 to October 26, 2019, all of which were "expenditure", and the column of "transaction type" was mainly displayed as "quick" and "consumption".

　　After the transaction on October 26, 2019, Wen Qingshu’s bank card had no transaction record. Until the afternoon of November 10, she went to the bank to withdraw money and found that the balance in the card was only 0.46 yuan.

　　Through speculation and repeated thinking, the family included their second daughter Xiang Moumou as a suspect.

　　family meeting

　　The second daughter admitted spending Cary’s money.

　　Used to recharge games and reward anchors.

　　Mr. Zeng, the son-in-law, told the Chengdu Business Daily-Red Star journalist that at 6 pm on November 10th, a family meeting was held at home, and the second daughter admitted that she had moved her mother’s bank card.

　　The second daughter confessed to her family that the money in the bank card was used by her, but it was not clear how much she used, except that after the last payment at the end of October, she could no longer use it. These 490 expenses totaled more than 74,000 yuan, all of which were used for game recharge and rewarding anchors.

　　Under the family’s questioning, the second daughter also admitted that the money was mainly used in two aspects, one was to buy "skin" in the game, and the other was to "reward" the anchor when watching the live game in the short video software. Mr. Zeng said that although Ermei deleted all the transaction records in the short video software and the game, she inquired about the payment records of Alipay, of which about 50,000 yuan was used for "rewarding" and about 20,000 yuan was used for buying equipment in the game.

　　The reporter looked at the contents of the games played to XXX, mainly role-playing games. In one of the game interfaces named "Fifth Personality", the role information played by XXX shows that the recharge data is 156,490, and the recharge amount is 15,649 yuan (without deducting the gift score) according to the rule that 1 yuan money is exchanged for 10 points set in the game.

　　According to Mr. Zeng, most of the deposits in the bank card are used to "reward" many live anchors in short video software, and almost all of them play role-playing games live. According to his incomplete statistics, the amount used to reward someone is about 50,000 yuan.

　　The girl involved

　　Recharge and reward are voluntary.

　　For "pride" and "nice clothes"

　　The girl told the reporter that she probably started to contact role-playing games at the beginning of last year, mainly focusing on the game of "fifth personality". She plays with her mobile phone every day when she comes home from school. Under normal circumstances, she plays games for two or three hours every day, and on weekends, she spends more time.

　　In the game, you can upgrade to someone by "fighting", and at the same time, you can purchase points by recharging cash to achieve rapid upgrade and buy different types of "skins" in the mall. Judging from the running list, the first recharge time to XXX was September 14th, 2019, and the recharge amount was 1 yuan money, and then it was increased one after another until it was expanded to watch live video and reward live anchors.

　　Xiang said that the mobile phone number she used was registered with her mother’s ID card, and then she quietly found her mother’s bank card, and registered Alipay through self-study, and then began to recharge.

　　From 1 yuan to 10 yuan, to 68 yuan, and then to 198 yuan, the highest single recharge of 1000 yuan … … After trying again and again, I found that my mother would not find out after each recharge, so the amount of recharge was increasing. In her opinion, Cary’s money is inexhaustible.

　　To say that every recharge is voluntary, and rewarding the anchor is voluntary. The reason for frequent recharge is: First, because it can be upgraded, there is pride in front of students who also play this game; Second, because you buy "skin" by recharging, you can have many beautiful clothes.

　　For the reporter’s question "Do you know how many clothes you can buy with the money you recharged in reality", I said "I don’t know" to XXX; The reporter asked, "Do you know what the money is for your mother and family?" He also said, "I don’t know."

　　Mother blames herself.

　　It is also responsible for not disciplining your daughter well.

　　I hope the platform will refund.

　　Wen Qingshu, the mother, blamed herself very much. She said frankly, "I don’t understand these high technologies", but the fact that her second daughter spent all her savings playing games at home also blamed her for not disciplining her daughter well on weekdays and should bear part of the responsibility.

　　Wen Qingshu said that this 70,000 yuan was accumulated in the past two years, when her husband worked outside the home and saved money. So much money was saved at home, and she hoped to save more for her second daughter and third daughter to study. Suddenly, all my savings are gone, and I feel very sad. I don’t know what to do. I hope the platform can get a refund.

　　At 9 o’clock on the evening of November 10, Wen Qingshu, accompanied by her eldest daughter and son-in-law, went to the local police station to report the case. On November 11th, Mr. Zeng, the son-in-law, took his second sister to the local cultural department to reflect this situation, and called the cultural department where the relevant game software was registered to tell the story and put it on record.

　　Mr. Zeng told reporters that they hope more parents can take warning, correctly guide and manage their children to play games, and avoid similar situations from happening again. At the same time, they also want to seek help through the media to understand the legal ways to recover related losses, hoping to get a refund.

　　Platform involved

　　If the minor rewards without the consent of the guardian

　　Once verified, a full refund will be made.

　　A few days ago, the Chengdu Business Daily-Red Star journalist also contacted the short video software platform used by Xiang Moumou. According to the relevant person in charge of the platform, first of all, the platform does not approve of minors to recharge their rewards when watching live broadcasts. If minors reward without the consent of their guardians, once verified, the platform will refund them in full. In addition, when minors use the software platform, parents can first turn on the youth mode in the interface. After this mode is turned on, content suitable for teenagers will be presented, and it is impossible to recharge the live broadcast.

　　In addition, the relevant staff of the production platform of the "fifth personality" game said that in the event of similar situations, parents are advised to make corresponding complaints through the "caring platform" of the platform. In addition, the platform suggests that parents can communicate with their children more and educate minors to play games reasonably. The platform will also work with parents to jointly protect the growth of minors.

　　Lawyer’s statement

　　A 13-year-old girl is a person with limited capacity for civil conduct.

　　Can declare a refund to the operating platform.

　　But guardians are also at fault.

　　Lawyer Zhang Shouyao of Sichuan Fangce Law Firm believes that the General Principles of Civil Law stipulates that minors over the age of eight are persons with limited capacity for civil conduct, and they can perform civil legal acts on their behalf or with the consent and ratification of their legal representatives, but they can independently perform civil legal acts that are purely beneficial or that are suitable for their age and intelligence.

　　Zhang Shouyao said that as far as the incident is concerned, the 13-year-old girl recharged the game and rewarded more than 70,000 yuan, which is no longer a civil act commensurate with her age and intelligence. If the legal representative does not ratify it, the act is invalid and she can request to return all the recharge and rewards. On the one hand, it can be solved through negotiation, and if necessary, it can seek help from the Consumers Association; If negotiation fails, it can be settled through litigation.

　　Lawyer Feng Jun, a member of the Rights Protection Committee of Sichuan Lawyers Association, said that the 13-year-old girl is a minor and a person with limited capacity for civil conduct in civil law, and she can make judgments on life matters corresponding to her current age. It is generally understood that it is ok for girls to play games such as video game city if they spend hundreds of dollars to buy game coins, but it is invalid to use more than 70 thousand yuan for game recharge one after another. Based on this, the game operator should return the prepaid money to the girl’s parents "because the girl’s big recharge behavior has not been approved by her parents".

　　Feng Jun said that as parents, they should fix evidence to prove that their parents are unaware of the large recharge behavior, and then report to the customer service phone of the game operation platform. If the platform refuses to accept it, they can file a lawsuit in the name of their parents and recover the money through judicial procedures. In addition, Feng Jun also said that in this incident, the girl’s parents, as guardians, failed to fulfill their guardianship responsibilities and bank card custody responsibilities, and they also had certain faults.

　　Recycling used lithium batteries is a good business.

　　However, at present, mainstream battery recycling enterprises have to face a big trouble, that is, the process of battery recycling consumes a lot of energy, has high economic cost, and will produce a large number of toxic by-products.

　　At the beginning of February, Lawrence Berkeley National Laboratory (LBL) announced on its official website that the relevant team of the laboratory had developed a Quick-Release Binder. When lithium-ion batteries using this quick-release binder are recycled, they only need to be disassembled and put into alkaline water at room temperature, and the electrode components can be separated by gentle shaking, and then the required components can be filtered out of the water and air-dried.

　　At present, the relevant teams are cooperating with onto technologies, an American battery recycling company, to conduct tests, which will soon be introduced to the market.

　　It is understood that the binder is a colloidal substance used in most types of batteries (including lithium-ion batteries and commonly used alkaline batteries). Every battery has two electrodes — — A positive electrode and a negative electrode. The electrode is made of conductive chemicals that generate current, and the adhesive binds these active chemical components together and fixes them in a proper position to achieve consistent and lasting performance.

　　The quick-release adhesive invented by Lawrence Berkeley National Laboratory staff is made of two commercially available polymer materials, polyacrylic acid (PAA) and polyethyleneimine (PEI), which are connected by chemical bonds between positively charged nitrogen atoms in PEI and negatively charged oxygen atoms in PAA.

　　When the solid bonding material is placed in a solution containing sodium hydroxide (Na+OH – ) in alkaline water, sodium ions will enter the connection site, thus separating the two polymer materials. The separated polymer dissolves in the liquid, releasing any electrode components embedded in it.

　　The left vial contains a copper foil of the battery current collector. After the quick-release adhesive is dissolved, the valuable electrode components in the battery have been completely released. In the vial on the right, the adhesive is rapidly dissolving in alkaline water. In contrast, the traditional binder strongly adheres the electrode material to the current collector like glue, which makes it difficult to separate and recycle the battery electrode material.

　　This is in sharp contrast with the current recycling of waste lithium-ion batteries. It is understood that taking the pyrometallurgical method of lithium-ion battery recycling technology as an example, it is necessary to chop and grind the battery and separate the metal and elements after combustion. The recycling process is not only high in energy consumption and cost, but also releases toxic chemicals that must be handled carefully.

　　The quick-release adhesive of Lawrence Laboratories team can be used to manufacture the positive and negative electrodes of batteries, and the price is about one tenth of that of the two most commonly used commercial adhesives for batteries.

　　Liu Gao, a senior scientist in the field of energy technology in Berkeley Lab, a member of the Energy Storage Center of Berkeley Lab and the project leader, said: "If we don’t stop burning batteries and throwing them into the trash can, we will run out of resources in the next decade. Cobalt and nickel are not enough, and we must recycle them, otherwise we can’t keep up with the market demand for batteries. "

　　Another member of the team said, "In the laboratory scale, preparation is very easy, and we don’t think it will be difficult to promote it to the commercial scale." The team believes that this material can be applied to batteries of all sizes, from small batteries in mobile phones to energy storage batteries in power grids.

　　The team’s tests show that this adhesive can be applied to various battery types, such as button cell in the picture.

　　In late September 2022, this technology was rated as one of the 100 revolutionary technologies developed globally in 2022 by R&D 100 Awards.

　　OnTo Technology, an American battery company, is working with Liu Gao’s team to complete product testing and bring it to market. The existing experiments show that the quick-release adhesive is very stable under high voltage and low voltage, and researchers now plan to use this adhesive to build a prototype lithium-ion battery to analyze its performance.

　　According to Steve Sloop, the founder of OnTo Technology, the rapid release of adhesive represents a paradigm shift in battery design. This design paradigm is no longer to design the battery first and try to create a recycling process afterwards, but to become the first design for recycling.

　　Assuming that the test goes well, the technology will smoothly transition to commercial manufacturing. Steve Sloop said, "The battery does not contain perfluoroalkyl and polyfluoroalkyl substances (PFAS), which is also a great achievement — — PFAS is a compound used to make non-stick coatings and many other products, but it may cause many health-related problems.

Just now, the official announcement of Xiaomi Automobile was finalized:

A technical conference was held on December 28, and Lei Jun emphasized that,Send-only technology.

News instantly rushed to the hot search:

Just a few days ago, Xiaomi Automobile also carried out"Technology giant, eco-car"The preheating, but unexpectedly attracted extremely kryptonian executives to open a group to ridicule.

The car has not been sent yet, and the frame has been noisy. The heat of Xiaomi car and the strength of giving it to friends can be seen.

After Tesla, another catfish is really coming!

Xiaomi Automobile: A technical conference will be held on December 28th.

Just now, Xiaomi Automobile officially announced on major platforms that it will hold a technical conference at 2 pm on December 28. Lei Jun immediately said:

This time, only technology will be distributed, not products.

Some bloggers speculate that many hardware parameters should be announced at the technical conference.

The location was not specified in the announcement, but considering that the time coincides with the "Millet Annual Science and Technology Feast", it is speculated that it should be Beijing.

From March 30, 2021, it was the spring conference of Xiaomi, and Xiaomi announced the official announcement to start building cars, which is just right today.1000 days.

This will be the most important press conference about Xiaomi Automobile in 1000 days.

In fact, the official account for the announcement was only opened on major platforms last night. On the Weibo platform, Lei Jun and Lu Weibing personally "drained" and sent Weibo @ Xiaomi Auto.

Lu Weibing also added, "Continue to work overtime tonight", so we saw the announcement just now.

The strongest catfish of the year is really coming.

Catfish attack: the car hasn’t started yet, and the plane has started to make noise.

Not long ago, Xiaomi Automobile carried out the pre-heating of "technology factory, eco-car". When this Slogan came out, it caused a hot discussion and debate for a while, and there were extremely embarrassing executives who couldn’t sit still and started a group.

Zhao Chunlin, vice president of Krypton, gave an example of an "ecological scene". Later, Weibo was deleted and a one-button protection mode was started:

Zhu Ling, vice president of Krypton, and Guan Haitao, CMO (chief marketing officer) also participated in the delegation. One of them took out Apple and Amazon to demonstrate the concept of "eco-car making":

Guan Haitao, a polar CMO who took office soon, then left a message in the comment area and mentioned a failure case that everyone is familiar with:

There’s nothing to hate about starting a group diss before the car leaves.

New enemies and old grievances.

On the first day of Xiaomi Automobile Technology Conference, December 27th happened to be the release time of Krypton 007.

It’s hard to say it’s a coincidence, because Krypton 007 was originally planned to be released in early January, but later it was advanced, just in time for the first day of Xiaomi Automobile Technology Conference.

Briefly introduce Krypton 007 and Xiaomi SU7:

Extreme krypton 007 pre-sale224,900 yuanStarting and wheelbase2928mmThe car is over 4.8 meters long.car, maximum endurance under CLTC condition870km, full stack800VHigh voltage architecture.

Xiaomi SU7, with a 3-meter wheelbase, the duty-free catalogue shows that there are models with a battery life of800km, will be equipped with 800V high-voltage platform.

Therefore, the positioning of the two cars belongs to the same C-class sedan, and the battery life is close. Both of them have 800V platforms, and each has its own advantages. It is a "new enemy".

There is still old hatred in the "new hatred"-

Guan Haitao, CMO, was the CMO of Glory China District before. In September this year, he left Glory to join Extreme Krypton.

In the era of smart phones, Xiaomi and Glory have been playing as close as a bee, taking the cost-effective route together, and the executives of both sides don’t know how many rounds they have bombarded on social platforms.

Especially after the car was started, Xiaomi also poached Hu Zhengnan, a senior executive of Geely and former president of Geely Research Institute, who is now an investment partner of Shunwei Capital founded by Lei Jun. Weibo’s whereabouts often coincide with the latest news of Xiaomi Automobile.

Even a bowl of jiaozi sent in the winter solstice a few days ago triggered a brain hole among netizens and guessed the price of Xiaomi SU7:

However, after the official announcement of Xiaomi Automobile, more netizens still ran to the "Zhengzhu" to urge them to make more progress. Xiaomi Automobile is getting closer and closer, and Redmi Automobile should also arrange it:

There are also bloggers who hope that Lei can always keep his original heart:

Still isShui clothing executives, is still19.99.

It is best to get a full refund after ten years like Xiaomi 1.

One More Thing

Just now, Huawei’s terminal issued an announcement, which started blind subscription at the autumn conference, and the M9 official announcement file of the "year-end great contribution" that has been preheated for a long time will be released at 2: 30 pm tomorrow on December 26th.

In the fiery smart car battlefield, Huawei and Xiaomi met again.

　　The Japanese side is keen on whitewashing what is wrong, trying to create the illusion that nuclear polluted water is safe and harmless by launching an intensive public relations offensive at home and abroad. This practice exposes its selfishness of not caring about the global marine environment and public health but only caring about its own interests.

　　The legitimacy, legality and safety of Japan’s plan to discharge nuclear polluted water into the sea have been questioned by the international community. Protests in Japan and neighboring countries have come and gone, and the voices of opposition from the international community have continued. Japan should have seriously responded to the concerns of the international community and made every effort to dispose of nuclear polluted water in a scientific, safe and transparent way. However, the Japanese side is keen on whitewashing what is wrong, trying to create the illusion that nuclear polluted water is safe and harmless by launching an intensive public relations offensive at home and abroad. This practice exposes its selfishness of not caring about the global marine environment and public health but only caring about its own interests.

　　The Japanese side pushed the plan of discharging nuclear polluted water into the sea, which was accompanied by a well-planned public relations offensive from the beginning. Established in 2012, Reconstruction Agency is responsible for the reconstruction of disaster areas, but the agency allocates public relations funds every year to instill in people the message that the impact of Fukushima nuclear accident has been eliminated. On April 13th, 2021, on the day when the Japanese government unilaterally decided to discharge the nuclear polluted water into the sea, Reconstruction Agency released the propaganda posters and videos made in advance in its official website, in an attempt to "win a good impression" by packaging the indelible radioactive elements in the nuclear polluted water into a mascot image. This move caused serious dissatisfaction among the Japanese people and the international community. The people of Fukushima indignantly pointed out that "(these propaganda) is completely out of place with the grim reality facing Fukushima." In the end, Reconstruction Agency had to withdraw the related products.

　　For more than two years, instead of learning a lesson, Japan has continued to carry out a series of publicity actions to the public around the so-called safety of nuclear polluted water. Many Japanese newspapers, TV stations, etc. publish and broadcast a large number of advertisements about the so-called safety of nuclear polluted water, disturbing and covering up people’s worries and opposition. The Japanese government has repeatedly called the nuclear polluted water that has been treated by the "multi-nuclide treatment system" but still contains many radionuclides "treated water" in an attempt to dilute its pollution characteristics and potential harm. The Japanese government has also set up a special fund with a total amount of 80 billion yen (about 4 billion yuan), and plans to provide "compensation" to the fishing-related industries in areas affected by the discharge of nuclear polluted water into the sea, in an attempt to avoid troubles with the so-called "compensation fee". This is another proof that the Japanese side covers up the harm of nuclear polluted water discharged into the sea.

　　The Japanese side has also stepped up its public relations with some countries, international institutions and organizations, trying to win over all parties to endorse its plan to discharge nuclear polluted water into the sea. In April this year, at the press conference of the meeting of ministers of climate, energy and environment of the Group of Seven, Japanese Minister of Economy, Trade and Industry Yasutoshi Nishimura said that the decommissioning of the Fukushima nuclear power plant, including the steady progress in the discharge of nuclear polluted water into the sea, would be welcomed. German Minister of Environment, Nature Protection, Nuclear Safety and Consumer Protection Lemcke retorted on the spot, saying that "we cannot welcome the discharge of nuclear polluted water into the sea". The Japanese government also used the NATO Summit, the East Asia Cooperation Series Foreign Ministers’ Meeting, the Eastern Caribbean Fisheries Ministers’ Meeting and other occasions to defend the Fukushima nuclear pollution water discharge plan.

　　Whether it is to launch a public opinion offensive at home or to lobby and win over internationally, the Japanese side has used its strength in the wrong place. All parties concerned strongly oppose Japan’s plan to discharge nuclear polluted water into the sea, and demand that Japan stop pushing the plan to discharge nuclear polluted water into the sea, fully communicate with stakeholders including neighboring countries in a sincere manner, effectively dispose of nuclear polluted water in a responsible manner, and accept strict international supervision. However, so far, Japan has been bent on promoting the plan of discharging nuclear polluted water into the sea, not only failing to fully study and demonstrate other disposal schemes, but also failing to seriously respond to the concerns of the international community. Its selfish approach has disappointed the international community.

　　No matter whether it is a public opinion offensive at home or lobbying internationally, Japan’s small moves can’t dispel the doubts of the domestic people and the international community about the discharge of nuclear polluted water into the sea. Recently, Japanese fishermen have repeatedly reiterated their opposition to nuclear pollution water discharging into the sea, and the opposition party in South Korea has also expressed the Korean people’s concerns and opposition to the plan through letters. People in many countries held protests in front of Japanese embassies and consulates in the Philippines, new york, Sydney and other places, demanding that Japan stop the plan of discharging nuclear polluted water into the sea. Because people are well aware that once Japan’s plan to discharge the sea is implemented, it will impose unpredictable nuclear pollution risks on the international community.

　　Discharging nuclear polluted water into the ocean is an adventurous gamble that harms human beings. Japan should face up to the concerns of the international community, shoulder its due moral responsibilities and obligations under international law, and find a proper way to dispose of nuclear polluted water. Until the concerns of the international community about the legitimacy of the nuclear polluted water discharge scheme, data reliability, effectiveness of purification devices and uncertainty of environmental impact are resolved, Japan should not start the nuclear polluted water discharge without authorization.

As many runners know, there are two kinds of running postures, namely, quick running and striding.

In fact, there is no difference between the two running methods. Runners can choose the running method that suits them according to their body shape and muscle strength.

This article will briefly analyze the characteristics and differences between the two for everyone.

First, the brisk running method

Trot refers to a running method that uses a smaller stride to speed up the pace frequency. This running method can not only reduce the up-and-down movement range of the body, ensure the stability of the running state, but also reduce the burden on the feet, which is suitable for practitioners who have no exercise habits.

There are several key points in brisk running:

Summary: The brisk running method can easily speed up or slow down the running pace by controlling the pace. When the exerciser wants to increase the speed, he will unconsciously increase the stride, which will increase the burden on his feet. Therefore, by speeding up the pace frequency, the running speed can be improved while minimizing the burden on his feet.

Second, the striding method

The striding method is different from the brisk running method. It is a kind of running method that can show vitality and be more ornamental by increasing the stride length to improve the speed.

It is reasonable to say that if we can speed up the pace frequency on the basis of increasing the stride, it will be the fastest running method, but the strode running method has a greater impact when landing, which requires runners to have corresponding muscle strength. Stride running is suitable for runners with good physical strength, strong muscle strength and long legs (higher height).

It is difficult for beginners to judge whether they have the muscle strength and physique needed for striding. Therefore, it is suggested to adopt brisk running first, and then gradually increase the stride to find the stride that suits them best.

The striding method has the following key points:

In short, determining the running method suitable for your body shape and muscle strength is helpful to achieve the goal of running the whole course or shorten the completion time.
