Beschreibung
Zusammenfassung:A positive electrode active material for nonaqueous electrolyte secondary batteries according to one embodiment of the present invention contains: a first lithium transition metal composite oxide that is represented by general formula LixNi1-y-zCoyMzO2 (wherein 0.8 ≤ x ≤ 1.2, 0 ≤ y ≤ 0.2, 0 < z ≤ 0.5, and M represents at least one metal element excluding Li, Ni and Co); and a second lithium transition metal composite oxide that has at least one diffraction peak which has a peak top at a diffraction angle (2Θ) of from 21.40° to 21.65° in radiation X-ray diffraction (with a light energy of 16 keV).
