Progress and perspectives on typical inorganic solid-state electrolytes

All-solid-state lithium batteries (ASSLBs) have received increasing attention due to the advantages of safety and energy density. The solid-state electrolytes(SSE5) is the main components in ASSLBs. Especially, in recent years, Inorganic SSE5 have made a progress. Inorganic SSE5 systems mainly include oxide SSE5, sulfide SSE5, and halide SSE5. The typical inorganic SSE5 have an ionic conductivity of similar to 10(-3) S/cm at room temperature, which is close to the level of ionic conductivity of liquid electrolytes. Herein, a comprehensive understanding of the development, material properties, and challenges of the inorganic SSEs above is provided. Personal viewpoints of SSEs research are presented.
