Abstract:
1. Li—Ni composite oxide particles for a non-aqueous electrolyte secondary battery, comprising a Li—Ni composite oxide whose secondary particles form core particles thereof and have a composition represented by the formula: in which 0.9≦x1≦1.3; 0.1≦y1≦0.3; 0.0≦z1≦0.3; 0.05≦w1≦0.1; and M is Al, wherein a Li—Ni composite oxide having a composition represented by the formula: in which 0.9≦x2≦1+z2; 0≦y2≦0.33; 0≦z2≦0.5; 0≦w2≦0.1; and M is Al with the proviso that 0.5≦(1−y2−z2−w2)/(y2+z2+w2), 0.3≦(z1+z2) and 0<(z2−z1)≦0.5), is coated or present on a surface of the respective secondary particles.
