Polaris Energy Storage Network News: China is the world's largest manufacturer of lithium batteries, and the world's second largest producer and exporter In recent years, the output value of China's lithium battery industry has grown from tens of billions of yuan to more than 100 billion yuan.

On April 25, Far East Smart Energy Co, Ltd.

In the early hours of September 5, Beijing time, Mercedes launched the eqc400 in Stockholm, Sweden It is the first electric model of the company's new energy line, the EQ brand.

With the listing of ningde times in China, few domestic enterprises can shake its leading position in the field of power battery under the advantage of using capital to fight for the market If there is, it can only be byd, which is preparing to break up its power battery business.

The power battery PACK product consists of three parts, namely the battery module, BMS, and the fixed frame housing The process includes the process of core assembly, welding, semi-finished product testing, labelling, and packing.

Lithium iron phosphate is a commonly used cathode material for lithium ion batteries, and it is favored by power battery manufacturers because of its good thermal stability and safetyThe relevant safety tests show that under the existing technical conditions, only lithium ion batteries using lithium iron phosphate materials can pass all safety tests and do not ignite or explode in acupuncture and compression experiments.

Chenjitao, male, studied at Peking University from 1992 to 1997, studied at Shuo Bo, Peking University from 1998 to 2003, studied postdoctoral studies at Peking University from 2003 to 2005, and stayed in school after graduating in 2005 He is currently an associate professor and doctoral tutor of Peking University, head of the key project of the National 863 plan for lithium iron phosphate, and concurrently serves as chairman of Qinghai Taifeng First Lithium Technology Co.

Due to the influence of material system and manufacturing process, lithium-ion batteries have the risk of internal short circuit Although lithium-ion batteries have undergone rigorous aging and self-discharge screening at the factory, due to process failure and other unpredictable use factors, there is still a certain degree of failure probability that leads to an internal short circuit during use.

Committee publicized the list of pilot companies for the dual integration management system in 2018 The lion technology was listed on the list, and the high score was recommended by the Guangdong Provincial Economic and Information Technology Committee to apply for the National dual integration management system in 2018.

With the gradual maturity of the safety of ternary materials in the power battery field, consumers have put forward higher requirements for the mileage of new energy vehicles In terms of policy, the competent department put forward corresponding requirements and technical indicators for the mileage of new energy vehicles, and made corresponding plans.
