Title:
PROCESS FOR PRODUCTION OF SULFIDE SOLID ELECTROLYTE MATERIAL, AND PROCESS FOR PRODUCTION OF LITHIUM SOLID-STATE BATTERY
Document Type and Number:
WIPO Patent Application WO/2012/001773
Kind Code:
A1
Abstract:
Disclosed is a process for producing a sulfide solid electrolyte material having high Li ion conductivity, which produces hydrogen sulfide in a reduced amount. Specifically disclosed is a process for producing a sulfide solid electrolyte material, which uses a raw material composition containing Li2S and P2S5, and is characterized by comprising a preparatory step of providing a crystallized sulfide solid electrolyte material, and an amorphisation step of subjecting the crystallized sulfide solid electrolyte material to an amorphisation treatment.
