Title:
METHOD FOR PRODUCING SULFIDE-BASED INORGANIC SOLID ELECTROLYTE MATERIAL, METHOD FOR PRODUCING PHOSPHORUS SULFIDE COMPOSITION, METHOD FOR EVALUATING PHOSPHORUS SULFIDE COMPOSITION, AND PHOSPHORUS SULFIDE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2024/101239
Kind Code:
A1
Abstract:
Disclosed is a method for producing a sulfide-based inorganic solid electrolyte material, the method comprising a step of obtaining a sulfide-based inorganic solid electrolyte material in a glass state by mechanically processing a starting material composition of the sulfide-based inorganic solid electrolyte material, the starting material composition containing lithium sulfide and a phosphorus sulfide composition, thereby vitrifying the components, while having the components chemically react with each other. With respect to this method for producing a sulfide-based inorganic solid electrolyte material, the phosphorus sulfide composition has three or more peaks within the 2θ range of 22.5° to 24.5° in the X-ray diffraction analysis spectrum as obtained by X-ray diffraction analysis.
