Abstract:
1. A cathode active material for a non-aqueous electrolyte secondary battery, comprising: secondary particles that are an aggregate of primary particles of a lithium nickel composite oxide expressed by the general expression: where 0.98≦w≦1.10, 0.05≦x≦0.3, 0.01≦y≦0.1, 0≦z≦0.05, and M is at least one metal element chosen from Mg, Fe, Cu, Zn and Ga, and where the crystallite diameter at (003) plane of the lithium nickel composite oxide that is found by X-ray diffraction and the Scherrer equation is within the range of 1200 Å to 1600 Å.
