Commercial lithium-ion batteries mostly use liquid electrolytes as electrolyte systems, which have problems such as insufficient electrochemical stability, low thermal stability and poor safety. The inorganic solid-state electrolyte has been a research hotspot in the current energy storage field because of its advantages of high electrochemical stability, high mechanical strength and so on. In this paper, the global patents in the field of inorganic solid-state electrolyte are taken as the research objects. By using patent data mining method, the technical layout, competitive advantage and core technology of the main institutions, and the development trend of the latest technology of sulfide electrolyte and oxide electrolyte are analyzed. Finally, suggestions were put forward to pay attention to the major needs of the country, accelerate the research and development of key technologies, and attach importance to the patent protection strategy. |
