Abstract
This positive electrode active material for a non-aqueous electrolyte secondary battery contains a lithium-transition metal composite oxide that has a rock salt-related structure and is represented by the compositional formula LiaMnbMcO2−XFx (in the formula: M is at least one metal element excluding Li and Mn; 2.000<a+b+c≤2.195; 1.0<a≤1.4; 0.4≤b≤0.9; 0≤c≤0.2; and 0.2≤x≤0.6). The metal element M preferably is at least one selected from Ni, Sn, Mo, Ti, W, Zn, and Al.
