The end of lithium batteries and the current dazzling new battery technology

　　Gaogong Lithium will invite Chinese companies and practitioners to participate in the exhibition every year, hoping to observe the Japan Battery Show from the perspective of these experts and practitioners in the lithium battery industry, and analyze the industrial changes and development behind the exhibition.

　　From February 28 to March 2, the 2018 Japan International Secondary Battery Energy Storage Exhibition (BATTERYJAPAN) was held at the Ariake Exhibition Center in Tokyo, Japan. As one of the largest battery exhibitions in the world, this exhibition brought together secondary batteries, capacitors, various related high-end technologies, materials, components, and advanced devices for the production and development of secondary batteries and capacitors, attracting a large number of global secondary batteries. Visitors from battery manufacturers, battery users, new-generation car manufacturers, and electronics manufacturers have become important windows for the development of the battery industry.　　 Gaogong Lithium will invite Chinese companies and practitioners to participate in the exhibition every year, hoping to observe the Japan Battery Show from the perspective of these experts and practitioners in the lithium battery industry, and analyze the industrial changes and development behind the exhibition.

　　The annual BatteryJapan arrived at the BigSight Convention and Exhibition Center in Tokyo as scheduled. During the visit, the power of China was felt everywhere: from a large number of Chinese visitors and exhibitors to two of the four keynote speeches from Chinese companies ( BYD and CATL). In the circle of friends, I saw some friends' sharing one after another, and there was also a lively live broadcast of Jiang Damei. I feel itchy for a while and want to write some of my own experiences and feelings. If there are any shortcomings and biases, please excuse me.

　　#BatteryJapan2018# Rising China's Lithium Battery Industrialization Force At the Battery Show in Japan, there is still a little pride to see the keynote speeches of Chinese companies. Some of the feelings after hearing it are summarized as follows: 　　Maxell　　 I personally feel a bit like an advertisement, but it is mentioned The technical route reached is still worth learning. By 2020, Maxell will use "solid electrolyte + high silicon anode", with the goal of increasing the battery capacity to 1.5 times the current capacity.　　BYD　　 pursues the closed loop of the lithium battery industry to cope with the problems caused by the shortage of Co resources and soaring prices. Tom pointed out that the solution provided by BYD is: 　　① Gradient utilization of lithium batteries: power batteries -> energy storage/unmanned logistics transfer robots, etc. -> battery recycling and resource reuse (95% of Co can be recycled).　　② Optimization of LFP cathode materials and selected end applications. For example, E6 now uses LFP batteries, but its cruising range can be further optimized to 400Km. Although the energy density of NCM or NCA is higher than that of LFP, LFP still finds applications in energy storage and electric buses.　　'S inspiration is: technology itself has no distinction between good and bad, but care about the appropriate application scenarios and the excellence of the technology.
