Zusammenfassung:Disclosed herein are a method of manufacturing a sulfide-based all-solid-state battery, and a sulfide-based all-solid-state battery manufactured thereby, wherein the battery includes a surface heat-treated positive electrode active material, which is simply performed by heating a positive electrode active material at 400° C. to 600° C. in an inert gas state, as a low-cost method of uniformly treating the surface of a positive electrode active material such that the positive electrode active material does not react with a sulfide-based solid electrolyte.
