摘要： A positive-electrode active material contains a lithium composite oxide, wherein the lithium composite oxide is a multiphase mixture having a first phase with a crystal structure belonging to a space group Fm-3m and a second phase with a crystal structure belonging to a space group other than the space group Fm-3m, and in an XRD pattern of the lithium composite oxide, the integrated intensity ratio I (18°-20°) /I (43°-46°) of a first maximum peak located at a diffraction angle 2θ in the range of 18 to 20 degrees to a second maximum peak located at a diffraction angle 2θ in the range of 43 to 46 degrees satisfies 0.05 ≤ I (18°-20°) /I (43°-46°) ≤ 0.90.

摘要： A positive-electrode active material contains a lithium composite oxide, wherein the lithium composite oxide has a crystal structure belonging to a space group Fd-3m, and the integrated intensity ratio I (111) /I (400) of a peak on the (111) plane to a peak on the (400) plane in an XRD pattern of the lithium composite oxide satisfies 0.05 ≤ I (111) /I (400) ≤ 0.90.
