Abstract
Provided is a sulfide-based solid electrolyte comprising lithium, phosphorus, sulfur, and a halogen, as a novel solid electrolyte capable of suppressing generation of hydrogen sulfide and securing ionic conductivity. The solid electrolyte is characterized by comprising LiPSHa(wherein Ha represents a halogen, and 'a' satisfies 0.2<a≤1.8) having an argyrodite-type crystal structure, and LiPS, wherein, in an X-ray diffraction (XRD) pattern obtained through measurement by an X-ray diffraction method, the ratio of the peak intensity of a peak appearing at a position in a range of diffraction angle 2θ=26.0° to 28.8° derived from LiPS, relative to the peak intensity of a peak appearing at a position in a range of diffraction angle 2θ=24.9° to 26.3° derived from the argyrodite-type crystal structure, is 0.04 to 0.3.
