Solid-state r6 batteryare expected to dominate the power battery technology route

　　The new energy vehicle market is developing rapidly, and the demand for power batteries continues to grow. Against this background, many listed companies have accelerated their deployment in the field of solid-state lithium batteries. Industry insiders say that solid-state batteries have longer driving range due to their higher energy density. With the improvement of comprehensive technical indicators such as cyclability and safety, the solid-state battery application market will gradually expand. Ganfeng Lithium, which has many advantages, said it is currently conducting extensive testing work on solid-state batteries and has set up a R&D center and a test production line in Ningbo to accelerate the commercialization of solid-state lithium battery technology. Currently, the company's solid-state r6 batteryare still in the experimental stage, but have passed a number of third-party safety tests. ...

　　Has many advantages

　　Ganfeng Lithium said it is currently conducting extensive trial work on solid-state batteries and has set up an R&D center and a trial production line in Ningbo to accelerate the commercialization of solid-state lithium battery technology. Currently, the company's solid-state r6 batteryare still in the experimental stage, but have passed a number of third-party safety tests.

　　On March 18, the first phase of the single large-capacity solid-state polymer power lithium-ion battery project invested and constructed by Fujian Provincial Bidding and Procurement Group was officially put into production. This power lithium-ion battery has recently passed authoritative inspection and testing. A 10.5-meter pure electric bus equipped with this power lithium-ion battery pack was tested last month and can safely run more than 410 kilometers on a single charge.

　　Power batteries are a key core component of new energy vehicles. According to the requirements of the "Technical Roadmap for Energy Saving and New Energy Vehicles", the energy density target of pure electric vehicle power batteries is 300Wh/kg by 2020, 400Wh/kg in 2025, and 500Wh/kg in 2030.

　　Compared with liquid lithium-ion batteries, solid-state r6 batteryhave the advantages of good safety performance, high energy density and long cycle life. Chen Liquan, an academician of the Chinese Academy of Engineering, previously said, "To further improve energy density, all-solid-state r6 batterymust now be considered. The mid- to long-term development of the electric vehicle industry requires technical reserves, and all-solid-state r6 batteryare expected to become the dominant technology route for the next generation of vehicle power batteries." "

　　Listed companies actively deploy

　　Judging from the current situation, BYD, Zhongtian Technology and other companies have launched plans in the field of solid-state lithium batteries.

　　In December 2017, Ganfeng Lithium announced that it planned to invest no more than 250 million yuan to build a first-generation solid-state lithium battery R&D pilot production line. According to the plan, samples of the first-generation solid-state lithium battery production line of 100 million watt hours will be delivered in December 2018; sales of 300 million yuan will be completed in December 2019, and the second-generation solid-state lithium battery technology is mature.

　　In November 2017, Yicheng New Energy announced that it planned to acquire 70% of the equity of Henan Pingmei Guoneng for 70 million yuan and enter the lithium battery manufacturing process. The 10GWh high-specific energy power lithium-ion battery project deployed by Pingmei National Energy has a total investment of 5 billion yuan.

　　Industry insiders believe that solid-state batteries are expected to solve the problem of low energy density and improve battery safety. All-solid-state lithium secondary batteries are expected to enter the terminal market in 2020. With the improvement of comprehensive technical indicators such as cyclability, rate, high and low temperature, and safety, the application of solid-state batteries in the electric vehicle market will gradually expand.
