Abstract
Li—Ni composite oxide particles for a non-aqueous electrolyte secondary battery with a large charge/discharge capacity and excellent thermal stability in a charged condition. The Li—Ni composite oxide secondary particles form core particles having a composition LiNiCoMnMOin which 0.9≦x1≦1.3; 0.1≦y1≦0.3; 0.0≦z1≦0.3; 0≦w1≦0.1; and M is Al or Fe. The Li—Ni composite oxide has a composition LiNiCoMnMOin which 0.9≦x2≦1+z2; 0≦y2≦0.33; 0≦z2≦0.5; 0≦w2≦0.1; and M is Al, Fe, Mg, Zr or Ti and is coated or present on a surface of the secondary particles.
