The development trend of solid-state fast charging lithium-ion batteries

　　Recently, Jiawei Longneng Solid Energy Storage Technology Rugao Company, located in Rugao Development Zone, officially put into production and trial operation. Its production has filled the gap in the production of lithium batteries in Rugao's new energy vehicle industry chain, and has further consolidated Rugao's industrial foundation as "China's most competitive pure electric vehicle production base".

　　Recently, Toyota and the Renault/Nissan/Mitsubishi alliance respectively stated that they aim to launch electric vehicles using solid-state batteries between 2022 and 2025. At the end of last year, Ganfeng Lithium also announced that it would build the first-generation solid-state lithium battery research and development pilot production line. Subverting traditional technology, solid-state batteries have become the new favorite "Solid-state batteries that take into account high energy density and high safety are not only an ultimate goal of battery technology, but also have a tendency to come and rain on a global scale." March 21, grace Dr. Che Yong, deputy general manager and CTO of Li Energy Technology Co., Ltd., told the reporter of Science and Technology Daily.　　Solid-state battery refers to an energy storage device in which no liquid is contained in the battery structure, and all materials exist in solid form. It is composed of "positive electrode material + negative electrode material" and solid electrolyte. Since solid-state lithium batteries have the advantages of good safety performance, high energy density and long cycle life, they are ideal power batteries for electric vehicles.
