Document Type and Number:
WIPO Patent Application WO/2021/132537
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a sulfide solid electrolyte having a small particle diameter and a low specific surface area; an electrode mixture, a slurry, and a battery using the sulfide solid electrolyte; and a method for producing the sulfide solid electrolyte. Provided is a sulfide solid electrolyte containing a lithium (Li) element, a phosphorus (P) element, and a sulfur (S) element, wherein a median diameter D50 is 0.10-2.0 μm, and the value of the following expression: (A×B)/C [in the expression, A represents a BET specific surface area (m2/g), B represents a true density (g/cm3), and C represents a CS value (m2/cm3)] is 1.0 to 2.5.
