Provided is a solid electrolytic composition including an active material, a first sulfide-based inorganic solid electrolyte; and a second sulfide-based inorganic solid electrolyte having a composition different from the first sulfide-based inorganic solid electrolyte, wherein the first sulfide-based inorganic solid electrolyte contains a halogen element, at least a part of the solid electrolytic composition is a crystalline phase, and the active material and the first sulfide-based inorganic solid electrolyte are in contact with each other. Further provided are an electrode sheet for full-solid secondary batteries as well as a full-solid secondary battery using the solid electrolytic composition, and a method for manufacturing an electrode sheet for full-solid secondary batteries, and a full-solid secondary battery. |
