Abstract: A sulfide solid electrolyte, which is able to adjust the morphology unavailable traditionally, or is readily adjusted so as to have a desired morphology, the sulfide solid electrolyte having a volume-based average particle diameter measured by laser diffraction particle size distribution measurement of 3 μm or more and a specific surface area measured by the BET method of 20 m2/g or more; and a method of treating a sulfide solid electrolyte including the sulfide solid electrolyte being subjected to at least one mechanical treatment selected from disintegration and granulation.

Abstract: A sulfide solid electrolyte may be able to adjust the morphology unavailable traditionally, or readily adjust so as to have a desired morphology. Such a sulfide solid electrolyte may include a substance including a lithium element, a sulfur element, and a phosphorus element; and an amine compound. The solid electrolyte may have a volume-based average particle diameter of 10 μm or less, measured by laser diffraction particle size distribution measurement, and/or a BET specific surface area of 40 m2/g or less.
