Abstract: The high safety and higher energy density of solid-state battery make it the focus of new energy technology research in various countries. China has also taken solid-state batteries as the direction for the development of the next generation of energy storage batteries. This article analyzes the current status and problems of the solid-state battery industry development in China with multiple methods. We hold that problems of solid state battery industry development can be summarized as follows:breakthroughs need to be achieved in key technical problems and in engineering preparation technology; the distribution of intellectual property rights needs to be optimized, and the technology development route need to be clearly designed. To address these problems, stronger policy support is needed to promote research on technological innovation; cooperation between industry, education, and research needs to be strengthened with clear development goals and strategy of diversified development, and transformation of research results need to be accelerated; priority should be given to development of solid-state battery industry through supporting leading enterprises, strengthening international cooperation and exploring new development models. With such efforts, the development system of high safety solid-state battery technology and industry can be constructed.
