This  project is the first international "combination of hardness and softness" polymer composite solid electrolyte. Adhering to the system design concept of "both power (rate), energy (quantity)", it has developed high specific energy, high safety, and high resistance with completely independent intellectual property rights. Deep sea pressure, long-service-life solid-state lithium batteries and deep-sea special power supply systems are the first to achieve all-sea and deep sea applications in the Mariana Trench, providing strong energy technology support for national deep-sea environmental exploration and scientific research. It has created a new situation in the application of deep-sea intelligent equipment in special power supply systems with high specific energy solid-state lithium batteries, established a world-class solid-state lithium battery R & D and production equipment platform, established a complete solid-state lithium battery technology system, and formed a key technology and core products with independent knowledge.
