Title:
SOLID ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2019/131725
Kind Code:
A1
Abstract:
The present invention pertains to a sulfide-based solid electrolyte that comprises lithium, phosphorus, sulfur, and a halogen, and proposes, as a novel solid electrolyte that is capable of suppressing generation of hydrogen sulfide and ensuring ion conductivity. The solid electrolyte is characterized by comprising Li3PS4 and Li7-aPS6-aHaa (wherein Ha represents a halogen, and 'a' satisfies 0.2
