BYD, Zhongtian Technology and other companies in the solid lithium battery field layout

With the rapid development of new energy vehicles, solid lithium batteries are in short supply in the electric car market. As a result, a number of listed companies accelerated the layout of solid lithium batteries.

Yanfeng Lithium announced that it plans to invest in the first-generation solid-state lithium battery R&D pilot production line with no more than 250 million yuan. According to the plan, in December 2018, the first-generation solid-state lithium battery production line of the billion-watt class was delivered, and in December 2019, it sold 300 million yuan, and the second-generation solid-state lithium battery technology was mature.

At the same time, Yi Cheng Xinneng also issued an announcement that it plans to acquire 70% of Henan Pingmei Guoneng's equity of 70 million yuan and cut into the manufacturing process of lithium batteries. The total investment of 10GWh high-power lithium-ion battery project of Pingmei National Power is 5 billion yuan.

There is no doubt that power cells are a key core component of new energy vehicles. According to the requirements of the "Roadmap for Energy Conservation and New Energy Vehicle Technology", by 2020, the energy density target for pure electric vehicle power cells is 300 W/kg.

It is worth mentioning that compared with liquid lithium ion batteries, solid state lithium batteries have the advantages of good safety performance, high energy density and long cycle life. Chen Liquan said, "Energy density should be further improved. It is now necessary to consider all-solid-state lithium batteries. The long-term development of the electric vehicle industry requires technical reserves, and all-solid-state lithium batteries are expected to become the leading technology route for the next generation of vehicle power batteries."

According to the daily securities network data, the Lithium industry is currently conducting extensive testing of solid-state batteries. A R&D center and a test production line have been established in Ningbo to speed up the commercialization of solid-state lithium battery technology; The first phase project of large capacity solid polymer power lithium-ion battery invested by Fujian Provincial Bidding and Procurement Group was put into operation. This type of power lithium-ion battery has recently passed the authoritative test. The 10.5 M pure electric bus carrying the powered lithium-ion battery pack was tested last month and can operate safely for more than 410 km on a single charge.

In addition, BYD, Zhongtian Technology and other companies have also carried out layout in the solid lithium battery field.

Professionals believe that with the improvement of comprehensive technical indicators such as recyclability, doubling rate, high low temperature, and safety, the application of solid-state batteries in the electric vehicle market will gradually expand and develop rapidly. Solid state batteries are expected to solve problems such as low energy density and battery safety. It is expected that all-solid lithium secondary batteries will enter the terminal market by 2020.
