Phased progress has been made in energy density solid-state lithium batteries. In terms of industrialization demonstration of high-energy-density, high-safety deep-sea solid-state lithium batteries, the company has conquered the key core technologies of deep-sea long-endurance power supplies, and has achieved the 11,000-meter pressure chamber test. And the whole deep-sea demonstration application, boosting the national deep-sea power supply to a new height.(Lithium - Ion Battery Equipment)
The fire accidents of Tesla electric vehicles have occurred one after another, and several domestic accidents have been very serious, and even the whole vehicle has been severely burned, which makes people re-examine the safety of commercial lithium-ion batteries. The liquid organic electrolyte in traditional lithium-ion batteries is the main culprit for the hidden danger of combustion and explosion. Although the battery management system can ensure the consistency and safety of the battery to a certain extent, when a puncture is caused by an external force collision, it is inevitable that the lithium-ion battery will catch fire and explode. Obviously, this cannot be solved by purely external battery management or physical peripheral protection. It is necessary to theoretically break through the design concept of lithium batteries, thereby fundamentally improving the safety of lithium batteries.
The use of solid electrolytes to replace traditional liquid electrolytes is considered to be the only way to substantially improve the safety of lithium batteries. However, due to a series of scientific issues such as the compatibility of solid-solid interfaces that need to be solved urgently and the immature technology for large-scale preparation of solid electrolytes, there has been no commercialized solid-state lithium battery with high energy density. Relying on the Qingdao Institute of Bioenergy and Process Research, Chinese Academy of Sciences, the Qingdao Energy Storage Industry Technology Research Institute (abbreviation: Qingdao Energy Storage Institute), with the support of the Chinese Academy of Sciences Nano Project, after years of exploration and development, has achieved high energy density solid-state lithium batteries. A series of progress has been made in the field of basic research, and 42 SCI papers have been published. In the industrialization demonstration of high-energy density, high-security deep-sea solid-state lithium batteries, the company has conquered the key core technologies of deep-sea and long-endurance power supply. , has achieved the 11,000-meter pressure chamber test and the full-sea deep-sea demonstration application, boosting the national deep-sea power supply to a new height.
