Research progress and the industrialization of all-solid-state battery
All-solid-state batteries using solid-state electrolytes instead of organic liquid electrolytes have the advantages of high safety and high energy density,providing a promising solution for next-generation energy storage devices.Although there is a general consensus in the industry on the trend of all-solid-state battery development,the industrialization of all-solid-state batteries is still facing many challenges,such as poor water-oxygen stability of the sulfide electrolytes and the interface between the cathode and the solid-state electrolyte,high interfacial impedance and poor processing performance of oxide electrolytes,as well as low ion conductivity at room temperature and narrow electrochemical windows of polymer electrolytes,which have not been solved yet,restricting the large-scale application of all-solid-state lithium batteries.Through investigation and research,this paper summarized the current status of all-solid-state lithium batteries technology development at home and abroad,analysed and proposed technical difficulties and solutions for all-solid-state lithium batteries,and finally looked forward to the future research directions of all-solid-state lithium batteries.
