POSITIVE ELECTRODE FOR ALL-SOLID-STATE BATTERY AND ALL-SOLID-STATE BATTERY COMPRISING SAME

A positive electrode for an all-solid-state battery and an all-solid-state battery comprising the same are provided. The positive electrode for an all-solid-state battery comprises a positive electrode active material, a sulfide-based solid electrolyte, a conductive material, and a binder, wherein the sulfide-based solid electrolyte comprises a first sulfide-based solid electrolyte containing bromine (Br) and a second sulfide-based solid electrolyte not containing bromine (Br), wherein the positive electrode active material comprises a core capable of reversible adsorption and release of lithium ions; and a coating layer formed on a surface of the core, wherein the coating layer comprises the first sulfide-based solid electrolyte.
