Abstract

Provided is a positive electrode material for a nonaqueous electrolyte secondary battery that excels in thermal stability. A positive electrode material for a nonaqueous electrolyte secondary battery, which is provided by the present invention, includes positive electrode active material particles that can reversibly store and release a charge carrier, and a metal hydroxide. Each of the positive electrode active material particles has inside thereof a void and the metal hydroxide is disposed inside the void.
