摘要：PROBLEM TO BE SOLVED: To provide a positive electrode material, a nonaqueous electrolyte secondary battery positive electrode and a nonaqueous electrolyte secondary battery, in which a crystal structure is suppressed from being collapsed during charge/discharge and which are excellent in safety.SOLUTION: A positive electrode material of the present invention is represented by LiNiMMMnO(where, 0.50<α≤1.33, 0.33≤γ≤0.80, 0≤η≤1.00, 0≤β<0.67, β+γ≤0.80 and 0≤ε≤1.00 are satisfied, Mrepresents at least one selected from Co and Ga, and Mrepresents at least one selected from among Ge, Sn and Sb), has a layered structure including a Li layer and a Ni layer, and includes a six-coordinated local structure involving Mand M. In a nonaqueous electrolyte secondary battery positive electrode 14 and a nonaqueous electrolyte secondary battery 1 of the present invention, the positive electrode material is used.SELECTED DRAWING: None
