Title:
SULFIDE-BASED SOLID ELECTROLYTE FOR LITHIUM SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2018/003333
Kind Code:
A1
Abstract:
Provided is a novel sulfide-based solid electrolyte which is capable of suppressing hydrogen sulfide generation which occurs due to reaction with moisture even when an electrolyte is brought into contact with dry air in a dry room or the like, and which is capable of achieving lithium ion conductivity. Proposed is a sulfide-based solid electrolyte for a lithium secondary battery, the sulfide-based solid electrolyte being characterized in that the surface of a compound containing lithium, phosphorous, sulfur, and halogen, and having a cubic Argyrodite type crystal structure is coated with a compound containing lithium, phosphorous, and sulfur, and having a non-Argyrodite type crystal structure.
