Disclosed herein are a sulfide-based all-solid-state battery and a method of manufacturing the same, wherein the sulfide-based all-solid-state battery includes a positive electrode active material coated with a lithium niobate precursor, which is manufactured by a polyol process having low production cost, such that it improves safety and increases capacity of the sulfide-based all-solid-state battery.

Sulfide-based all-solid-state battery including positive electrode active material coated with lithium niobate precursor and method of manufacturing the same

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&#xb0; C. to 600&#xb0; 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.
