Abstract

As the next-generation power battery technology of solid-state batteries, the solid-state electrolytes are the core material of solid-state batteries. Therefore, developing appropriate solid-state electrolytes is the key issue to achieving high safety and high energy density all-solid-state batteries. Ideally, solid electrolytes should meet the needs of practical applications in terms of ionic conductivity, air stability, and cost competitiveness. However, current commercialized oxide, sulfide, and polymer solid electrolytes cannot meet the above requirements at the same time. The new halide solid-state electrolyte has the advantages of high lithium ion conductivity, good mechanical deformability and high oxidation stability, and can successfully realize the application of high-performance halide-based all-solid-state batteries. This article reviewed the research and development of low-cost halide solid-state electrolytes and key research issues, and finally put forward the research prospects in order to promote the industrialization of solid-state batteries.
