Abstract
A cathode active material capable of improving chemical stability, a method for producing the same, and a nonaqueous electrolyte secondary battery using the same which has high capacity and good charge-discharge cycling characteristics is provided. The cathode has a cathode active material. The cathode active material includes a coating layer formed on at least a part of the composite oxide particle, the coating layer including an oxide including lithium and an oxide including a coating element of nickel, or nickel and manganese, and a surface layer formed on at least a part of the coating layer and containing molybdenum.
