　　Battery technology is ushering in changes. Are batteries the next trend in power batteries?

　　Due to its obvious performance advantages in safety, reliability, energy density, cycle life and other aspects, solid-state batteries are considered by the industry to be an ideal next-generation battery technology system.

　　On November 19, 2018, Qingtao Development announced that it had put into production the country's first solid-state lithium battery production line, and had developed an all-solid-state battery with a single energy density of 430Wh/kg. In the mass production stage, the energy density can easily Reaching more than 300Wh/kg can meet the challenge of achieving the national requirement of 300Wh/kg by 2020.

　　With the existing liquid lithium battery material system, it is almost impossible to achieve an energy density of more than 350Wh/kg. Some foreign research institutions even predict that mass production of solid-state batteries will begin in 2022, and the demand for lithium batteries will be less than 1% by 2025. Therefore, solid-state batteries have become the focus of competition for companies to deploy next-generation batteries.

　　Internationally, industrial giants and technology companies such as Toyota, Nissan, Honda, Volkswagen, Mercedes-Benz, BMW, Hyundai, Mitsubishi, Hitachi, Apple, Panasonic, Samsung, Dyson, and 24M have also been involved in the research and development of solid-state batteries and have even begun to test the waters for commercialization. .

　　In China, CATL, Guoxuan High-Tech, Yiwei Lithium Energy, Xiongtao Technology, Penghui Energy, Ganfeng Lithium Industry, Hengdian East Magnetics, Jiawei Technology, Shanshan Technology, Dangsheng Technology, Huineng Technology, Qingtao Technology Development and the Chinese Academy of Sciences, Tsinghua University, Zhejiang Changxing Sino-Russian New Energy Materials Technology Research Institute, etc. have announced that they are developing solid-state batteries and related materials.

　　In terms of policy, in 2017, four ministries including the Ministry of Industry and Information Technology jointly issued the "Action Plan to Promote the Development of the Automotive Power Battery Industry", which clearly requires vigorously promoting the research and development and industrialization of new lithium-ion power batteries and increasing investment in the research and development of new batteries such as solid-state batteries.

　　At the same time, since Japan's Sony released the first commercial lithium-ion battery in 1991, lithium battery technology has continued to come out of the laboratory in the past 28 years, but it has not yet achieved true innovation.

　　From liquid to all-solid state, the curtain of battery technology innovation is about to begin. How will the next generation of battery technology be upgraded? Are solid-state batteries the next trend in power batteries? How do domestic companies seize the opportunity to patent solid-state battery technology? What are the core materials and technical process bottlenecks of solid-state batteries? How does smart equipment adapt to the development needs of the solid-state battery industry? What is the market application space and potential of solid-state batteries?
