Abstract
Provided are a method for producing a sulfide solid electrolyte having a high Li ion conductivity, in which the production time can be greatly reduced, and a sulfur-based material that can be used in the production method for a sulfide solid electrolyte. The invention relates to a method for producing a sulfide solid electrolyte containing a lithium element, a sulfur element, a phosphorus element, an iodine element and a bromine element, which includes mixing and grinding lithium sulfide and lithium bromide followed by adding phosphorus sulfide and lithium iodide thereto and reacting them, and relates to a sulfur-based material.
