CR1632 battery

　　CR1632 battery technology is gradually upgraded, waiting for mass promotion and application

　　According to research, the comprehensive cost of semi-solid and all-solid batteries is 200%-300% of existing lithium-ion batteries. It is expected that by 2025, domestic breakthroughs and matching of some key materials will be achieved, and batch costs will be reduced.

　　Industry Status

　　Recently, we investigated companies in the CR1632 battery industry and communicated with experts on the current status of the industry and the progress of domestic and foreign companies. Mainstream companies in the industry predict that mass sales will be achieved by 2020, and that all-CR1632 battery technology will be mature and costs can be controlled to achieve large-scale industrial application in 2025.

　　Comment

　　Solid-state batteries are the next generation battery technology that is widely recognized as lithium-ion batteries. The goal is to solve the needs of new energy vehicles for safety and long battery life. The rapid development of the global new energy vehicle market has put forward higher requirements for battery safety and energy density. The "Energy Saving and New Energy Vehicle Technology Roadmap" proposes the development of all-solid-state lithium-ion battery technology in 2025, and the energy density of battery cells in 2025 and 2030 respectively. Reaching the goals of 400 and 500wh/kg, the energy density is 66% higher than the existing electrolyte lithium-ion battery, and the CR1632 battery will not suffer from thermal runaway and has better safety performance.

　　Breakthroughs in technology of some key materials and cost reduction are the core difficulties for large-scale promotion. Solid-state batteries are an upgrade of current lithium-ion battery technology. The development path is semi-solid → quasi-solid → all-solid. The important differences are that the solid electrolyte replaces the electrolyte, does not require a separator, and ultimately replaces the graphite anode with a metallic lithium anode. According to research, the comprehensive cost of semi-solid and all-solid batteries is 200%-300% of existing lithium-ion batteries. We predict that by 2025, domestic breakthroughs and matching of some key materials will be achieved, and batch costs will be reduced.
