After the battery pack with the thickness of nail plate is cut, it does not explode and can still supply power normally; Bending for 10000 times, the battery capacity attenuation shall not exceed 5%; The appearance of solid lithium battery with high energy storage and significantly improved safety has shocked the battery industry.
On November 19, Suzhou Qingtao New Energy Technology Co., Ltd., located in Kunshan, Jiangsu Province, officially put into production a solid state lithium battery production line that can produce 10000 solid state batteries per day. The battery energy density can reach more than 400Wh. The products will be mainly used in special power supply, high-end digital and other fields.
As the "heart" of new energy vehicles, power batteries will undoubtedly determine the future of new energy vehicles. According to incomplete statistics, China's power lithium battery shipment in 2017 was 39.2GWh, with a year-on-year growth of 28.5%. Industry insiders predict that it will maintain a compound growth rate of more than 25% by 2030.
If buses, aircraft and ships will also be powered by batteries in the future, more power will be needed. However, the evolution speed of the current water-based lithium battery performance is slowing down. As a result, the plastic solid state battery will become the development direction of the next generation of lithium batteries, including Toyota, Toshiba, Apple, BMW, Mercedes Benz, Volkswagen and other internationally renowned enterprises.
Suzhou Qingtao New Energy Technology Co., Ltd., founded by Academician Nan Cewen of Tsinghua University, is one of the earliest teams to carry out the research and development of all solid state lithium battery technology in China. Focusing on the research and development of solid lithium batteries, the company has applied for nearly 100 patents, solved a series of problems such as the mass production of solid electrolyte materials, solid electrolyte membrane forming technology, composite positive and negative electrode formula process, solid solid interface between electrode sheet and electrolyte membrane, and successfully realized the industrialization of research and development achievements such as oxide solid electrolyte materials, functional ionic conductor ceramic composite membranes.(Lithium - Ion Battery Equipment)
Nan Cewen, an academician of the CAS Member, believes that solid state lithium batteries have stronger driving force, larger energy reserves, and can realize faster charging and longer duration. At the same time, since solid electrolyte is nonflammable, non corrosive, non volatile, and does not leak, it will not catch fire even at high temperatures, so it has higher safety. Autoignition probability of vehicles equipped with all solid state lithium batteries will be greatly reduced.
The solid state lithium battery production line, which can produce 10000 solid state batteries per day, has been officially put into operation, and a complete independent intellectual property system has been established, forming an industrial ecosystem 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. Another six production lines are being prepared to meet the needs of automotive enterprises in power batteries by 2020.
"The mass production of solid lithium batteries has built an industrial ecological chain of 'new energy materials - solid 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 promote the development of lithium batteries towards miniaturization, miniaturization and flexibility, redefines the form of lithium batteries, breaks the traditional square or cylindrical form, and can be made into Parts of any shape improve space efficiency. " Li Zheng, general manager of Suzhou Qingtao New Energy Technology Co., Ltd.
At the beginning of this month, Academician Nan Cewen's team was awarded the first batch of Kunshan "Touyan Talents" and teams, and was awarded a project subsidy of 100 million yuan by the local government.
