A cathode material contains Li2NiαM1 βM2 γMnηO4-ε, where α satisfies a relational expression 0.50 < α ≤ 1.33, γ satisfies a relational expression 0.33 ≤ γ ≤ 0.80, η satisfies a relational expression 0 ≤ η ≤ 1.00, β satisfies a relational expression 0 ≤ β < 0.67, β and γ satisfy a relational expression β + γ ≤ 0.80, ε satisfies a relational expression 0 ≤ ε ≤ 1.00, M1 is at least one selected from Co and Ga, and M2 is at least one selected from Ge, Sn, and Sb. The Li2NiαM1 βM2 γMnηO4-ε has a layered structure that includes a Li layer and a Ni layer, where M1 and M2 have a hexacoordinate local structure. |
