SOLID SULFIDE ELECTROLYTE MATERIAL, SOLID-STATE LITHIUM BATTERY, AND METHOD FOR MANUFACTURING SOLID SULFIDE ELECTROLYTE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a solid sulfide electrolyte material having high Li ion conductivity.SOLUTION: The solid sulfide electrolyte material contains Li, A representing at least one kind of element selected from P, Si, Ge, Al, and B, X representing a halogen, and S, is a glass ceramic material, and shows peaks at 2=20.2° and 2=23.6° when subjected to an X-ray diffraction measurement with the CuK ray. The solid sulfide electrolyte material preferably contains an ion conductor containing Li, A representing at least one kind of element selected from P, Si, Ge, Al, and B, and S; and LiX, where X represents a halogen.
