Summary:PROBLEM TO BE SOLVED: To provide a positive electrode active material hard to cause the decomposition of a nonaqueous electrolyte solution even at a high operating potential.SOLUTION: A positive electrode active material disclosed herein comprises at least one composite oxide selected from the group consisting of a spinel-based lithium nickel manganese composite oxide, a layered lithium composite oxide, and a lithium-excessive layered lithium composite oxide. The at least one composite oxide is doped with nitrogen.SELECTED DRAWING: Figure 3 【課題】作動電位が高くなっても非水電解液の分解を起こし難い正極活物質を提供する。【解決手段】ここに開示される正極活物質は、スピネル系リチウムニッケルマンガン複合酸化物、層状リチウム複合酸化物、およびリチウム過剰層状リチウム複合酸化物からなる群より選ばれる少なくとも１種の複合酸化物を含有する。そして、当該複合酸化物に、窒素がドープされている。【選択図】図３
