Electrode body, all solid state battery, and method for producing coated active material

摘要

The problem of the present invention is to provide an electrode body in which electron conductivity of a coated active material improves and reaction resistance decreases. The present invention solves the above-mentioned problem by providing an electrode body comprising a coated active material having an oxide active material and a coat layer for coating the surface of the above-mentioned oxide active material, containing an oxide solid electrolyte material, and a sulfide solid electrolyte material contacting with the above-mentioned coated active material, characterized in that the above-mentioned coat layer contains a conductive assistant.
