Solid state lithium battery technology route -Lithium - Ion Battery Equipment

With the rapid development of the new energy vehicle market, the demand for power lithium-ion batteries continues to rise. In this context, many listed companies have accelerated the layout of solid-state lithium-ion batteries. Industry insiders said that solid state batteries have a longer range due to their higher energy density. With the improvement of recycling, safety and other comprehensive technical indicators, the solid-state battery application market will gradually expand.(Lithium - Ion Battery Equipment)

Have many advantages

Ganfeng Lithium said that it is currently conducting extensive tests on solid state batteries and has set up a research and development center and a test production line in Ningbo to accelerate the commercialization of solid state lithium-ion battery technology. At present, the company's solid-state lithium-ion battery is still in the experimental stage, but has passed a number of third-party safety tests.

On March 18, the first phase of the single large capacity solid polymer power lithium ion battery project invested and constructed by Fujian Provincial Bidding Procurement Group was officially put into operation. This power lithium ion battery has recently passed the authoritative inspection. The 10.5m pure electric bus equipped with the power lithium-ion battery pack was tested last month, and it can safely run for more than 410km after a single charge.

Power lithium-ion battery is the key component of new energy vehicles. According to the requirements of the Technical Roadmap for Energy Saving and New Energy Vehicles, by 2020, the energy density target of lithium-ion battery for pure electric vehicle power will be 300Wh/kg, 400Wh/kg in 2025 and 500Wh/kg in 2030.

Compared with liquid lithium-ion battery, solid lithium-ion battery has the advantages of good safety performance, high energy density and long cycle life. Chen Liquan, academician of the Chinese Academy of Engineering, said earlier that "to further improve the energy density, it is now necessary to consider all solid state lithium-ion batteries. The medium and long-term development of the electric vehicle industry requires technical reserves, and all solid state lithium-ion batteries are expected to become the leading technology route of the next generation of lithium-ion batteries for vehicle power."

Active layout of listed companies

From the current situation, BYD, Zhongtian Technology and other companies have carried out layout in the field of solid-state lithium-ion batteries.

In December 2017, Ganfeng Lithium announced that it planned to invest no more than 250 million yuan to build a pilot production line for the research and development of the first generation of solid-state lithium-ion batteries. According to the plan, the first generation solid state lithium ion battery production line of 100 million watt hours will deliver samples in December 2018; In December 2019, the sales of 300 million yuan was completed, and the technology of the second generation solid state lithium ion battery was mature.

In November 2017, Yicheng Xinneng announced that it planned to acquire 70% of the equity of Henan Pingmei Guoneng for 70 million yuan to enter the lithium ion battery manufacturing process. The total investment of the 10GWh high specific power lithium ion battery project of Pingdingshan Guoneng is 5 billion yuan.

Industry insiders believe that solid state batteries are expected to solve the problem of low energy density and improve the safety of batteries. It is expected that all solid state lithium secondary batteries will enter the terminal market in 2020. With the circulation
