Abstract
A positive electrode material includes: LiNiMMMnOthat has a layered structure including a Li layer and a Ni layer, and in which a Ni—O bond length is shorter than that calculated from the Shannon's ionic radii. α satisfies a relation of 0.50<α≤1.33, β satisfies a relation of 0≤β<0.67, γ satisfies a relation of 0.33≤γ≤1.1, η satisfies a relation of 0≤η≤1.00, ∈ satisfies a relation of 0≤∈≤1.00, Mrepresents at least one selected from Co and Ga, Mrepresents at least one selected from Ge, Sn and Sb. A positive electrode material may indicate a peak intensity ratio (I/I) of 0.9 or more in a measurement of a powder X-ray diffraction indexed with a space group of R3m.
