China's solid-state lithium battery has achieved mass production of electric vehicles or will usher in the battery revolution
the battery pack with the thickness of the fingernail has been knocked out by one lift. After being cut by three theft and criminal gangs, it has not exploded and can still supply power normally; Bend 10000 times, and the battery capacity attenuation shall not exceed 5%; The appearance of solid-state lithium batteries with high energy storage and significantly improved safety shocked people in the battery industry
on the 19th, in Suzhou Qingtao Xinnengyuan Technology Co., Ltd., located in Kunshan, Jiangsu Province, a solid-state lithium battery production line with a daily output of 10000 solid-state batteries was officially put into production, with a battery energy density of more than 400wh. The products will be mainly used in special power supplies, high-end digital and other fields
as the "heart" of new energy vehicles, the pointer should return to zero after air strike under normal conditions, the power battery will undoubtedly determine the future of new energy vehicles. According to incomplete statistics, China's power lithium battery shipments in 2017 were 39.2gwh, an increase of 28.5% year-on-year. Industry insiders predict that by 2030, it will maintain a compound growth rate of more than 25%
if buses, planes and ships are also powered by batteries in the future, more power will be needed, and the current performance evolution speed of waterborne lithium batteries is slowing down. Therefore, the plastic solid-state batteries have become the development direction of the next generation of lithium batteries, including Toyota, Toshiba, apple, BMW, Mercedes Benz, Volkswagen and other internationally renowned enterprises have layout in this field
Suzhou Qingtao New Energy Technology Co., Ltd., founded by the nancewen academician team of Tsinghua University, is one of the early teams in China to carry out the research and development of all solid-state lithium battery technology. Focusing on the research and development of solid-state lithium batteries, the company has applied for nearly 100 patents, overcome a series of problems such as mass production of solid electrolyte materials, solid electrolyte membrane forming technology, composite anode and cathode formula process, solid-solid interface between electrode sheet and electrolyte membrane, and successfully realized the industrialization of R & D achievements such as oxide solid electrolyte materials and functional ionic conductor ceramic composite diaphragm
Nan cewen, an academician of the Chinese Academy of Sciences, believes that solid-state lithium batteries have stronger driving force and greater energy reserves, which can realize faster charging and longer duration. At the same time, because the solid electrolyte is nonflammable, non corrosive, non volatilizing and non leaking, it will not catch fire even at high temperature, so its safety is higher. Vehicles equipped with all solid-state lithium batteries will greatly reduce the probability of spontaneous combustion
the solid-state lithium battery production line with a daily output of 10000 solid-state batteries has been officially put into operation, and an independent intellectual property system has been established in which vegetable stalls in the community and roadside vendors are all plastic bags, forming an industrial ecological chain of "new energy materials - solid-state energy storage technology - automation equipment - comprehensive utilization of battery resources - incubation of scientific research achievements - industrial investment".

it is reported that the first production line currently in mass production mainly produces high-energy density solid-state lithium-ion batteries, large capacity flexible solid-state batteries and high safety solid-state batteries, and another six production lines are under preparation, striving to meet the needs of vehicle enterprises in power batteries by 2020
"The mass production of solid-state lithium batteries has built an industrial ecological chain of 'new energy materials - solid-state energy storage technology - automation equipment - comprehensive utilization of battery resources - incubation of scientific research achievements - industrial investment', which provides a new path to improve the energy storage of lithium batteries, helps to promote the development of lithium batteries to miniaturization, miniaturization and flexibility, redefines the form of lithium batteries, breaks the traditional square or cylindrical form, and can be made in the future Components of any shape improve space efficiency. " Li Zheng, general manager of Suzhou Qingtao New Energy Technology Co., Ltd., said
at the beginning of this month, the academician team of nancewen was awarded the first batch of "head geese talents" and teams in Kunshan City, and was awarded a project subsidy of 100million yuan by the local government
