Research progress in sulfide electrolytes for all-solid-state Li-ion battery
The sulfide electrolyte system for all-solid-state Li-ion battery has advantages of high ionic conductivity,simple preparation method,good ductility,and stable electrochemical performance.However,it is still difficult to apply on a large scale.The research of sulfide-based electrolyte for all-solid-state Li-ion battery is reviewed.The type of electrolytes including glass,glass ceramic and crystal is introduced,the common preparation methods of sulfide solid electrolytes are listed,the existing problems of cathode-electrolyte interface,anode-electrolyte interface and electrolyte stability are summarized and the relevant solutions are also provided.The application of sulfide electrolyte in all-solid-state Li-ion battery is prospected.
