POSITIVE ELECTRODE BODY FOR NONAQUEOUS ELECTROLYTE BATTERY, METHOD FOR PRODUCING SAME, AND NONAQUEOUS ELECTROLYTE BATTERY

摘要

Disclosed is a positive electrode body for a nonaqueous electrolyte battery, which suppresses increase in interface resistance by suppressing the formation of a high resistance layer at the contact interface between a positive electrode active material particle and a solid electrolyte particle. Specifically disclosed is a positive electrode body (1) for a nonaqueous electrolyte battery, wherein coated positive electrode active material particles (10), each of which is obtained by covering the surface of a positive electrode active material particle (10a) with a coating layer (10b) that has Li ion conductivity, and sulfide solid electrolyte particles (11) are mixed. The coating layer (10b) is formed from an amorphous oxide having oxygen deficiency. By having oxygen deficiency in the coating layer (10b), Li ion conductivity and electron conductivity sufficient for charge and discharge of a battery can be stably secured in the coating layer (10b).
