New lithium battery technology or M9 in the car, higher safety and longer service life

As the launch date of the M9 is approaching, more and more information is being exposed. Recently, people close to the supply chain revealed that lithium battery innovative material composite current collectors are expected to be applied to the M9.

The composite current collector is a sandwich structure superimposed by "metal-PET/PP polymer material-metal", replacing the original pure metal foil. With the application advantages of high safety, long life, high energy density and low raw material cost, it is expected to replace the traditional current collector and become the mainstream material of lithium battery current collector in the future.

GAC Aian released the magazine battery 2.0, which is the first battery in China to announce the use of composite current collectors. The first model is the Haobo GT. At the car launch, Aian also announced the test report of the fully charged battery pack fired by bullets. The results showed that the bullets penetrated three cells, causing an instant internal short circuit and explosive damage to the cells. However, the battery pack only smoked and did not catch fire, and the temperature dropped to room temperature after standing for 24 hours.

In addition, the Ningde era Kirin battery has adopted a composite current collector and is mounted on the pure electric MPV electrode Krypton 009.

The CITIC Construction Investment Research Report believes that the composite collector is both safe and economical, and is a major innovation in lithium batteries. In 2023, the industrial trend will gradually become clear to significantly accelerate, and equipment manufacturers, new copper foil factories, battery factories and end users will accelerate their layout. At the same time, technological breakthroughs continue to promote the production of composite collector vectors, and 2023 is expected to become the first year of mass production.

Jiangxi Nanchang strictly investigates drunk driving and urges "drunk driving" service

  "A drop of wine for a driver, two lines of tears for a loved one." The reporter recently found that as the city’s traffic violations against drunk driving have been stepped up, "drunk driving" services have quietly emerged in the city. Relevant departments pointed out that the "drunk driving" industry needs to be regulated urgently.


  Strictly investigate drunk driving to urge heat "drunk driving"


  It is understood that "drunk driving" refers to the driving company providing driving services to drivers or customers who are unable to drive after drinking. In recent months, the city has strengthened the rectification of traffic violations against drunk driving, and large hotels, guesthouses and surrounding intersections have also set up checkpoints. Mr. Zhou, who has tried the driving service once, said that he usually drove to socialize without drinking, but he did not dare to drive back by himself after drinking, and sometimes it was helpless to find someone to "drive".


  An industry insider who is engaged in "drunk driving" services told reporters that their company’s business volume has continued to rise in recent months, receiving more than 20 transactions in two months, an increase of 30% compared with the previous monthly business volume. The reporter found in the investigation that many hotels in our city have launched "drunk driving" services one after another, and some applicants have increased their chances of being hired if they can drive. The industry insider said that the group engaged in this industry will continue to expand and gradually radiate to the entire service industry.


  "Driving on behalf of" prices vary


  In the past two days, the reporter has received "drunk driving" service cards at the entrance of many hotels in our city, and these hotels all provide "drunk driving" service. "What should I do if I have frequent holiday parties and drink too much and can’t drive? It doesn’t matter, we can send you home safely!" At the entrance of a hotel on Rongmen Road, a warm reminder of "driving" cards was placed on the wipers of various cars.


  In order to further understand the service category, the reporter then consulted the hotel’s lobby manager Li as a customer. According to her, their hotel also launched this service at the end of the previous year. Among them, the "driving" service includes errands, pet pick-up, door-to-door delivery, station pick-up, "drunk driving" and other services, and the price depends on the degree of labor output.


  On the card distributed by the hotel, the charging standard is marked: if you "drive" in the urban area, the charging standard is 30 yuan/hour, plus the driver’s return taxi fee, and it is said to provide a regular invoice. The reporter found at the entrance of several other hotels that the charging standard for the "driving" service launched by each hotel is uneven, and the price fluctuation of the same type of service is almost 20 yuan to 30 yuan. Among them, one hotel charges: 200 yuan starting, after 11 pm, the price will be increased by 50 yuan/hour. If you serve in the suburbs, you will have to increase the price. Some hotels say that the "driving" in the city is 50 yuan at a time, and 80 yuan at a time outside the city.


  It is best to clarify the division of responsibilities before driving


  Li Zhuqing, a lawyer from Jiangxi Hongcheng Law Firm, believes that according to the judicial interpretation of the Supreme People’s Court, as long as the operation is prohibited by law, the behavior should generally be considered valid. Helping people drive is a business project of the company for profit, so in addition to the safety of the vehicle itself, the damage to the vehicle should bear full fault liability. He suggested that the division of responsibilities should be clearly defined before driving to avoid unclear division of responsibilities such as traffic accidents.


  The "driving" service market needs to be regulated urgently


  The staff of the Municipal Bureau of Industry and Commerce told reporters that although the "driving" service is beyond the scope of the company’s registration, the "driving" service is a value-added service of transportation services and does not violate relevant regulations. However, the current "driving" service is very irregular in our city, and this special service needs to be uniformly regulated by the market. (Trainee reporter Deng Wang reporter Yang Kai)
