Abstract

A structurally inhomogeneous lithium metal oxide material having the Formula (I): y[xLi2MO3•(1-x)LiM′O2]•(1-y)Li1+dM″2−dO4; wherein 0≤x≤1; 0<y<1; 0≤d≤0.33; and wherein the Li1+dM″2−dO4 component comprises a spinel structure, and each of the Li2MO3 and the LiM′2 components thereof comprise layered structures. Each of M, M′, and M″ independently comprises one or more metal ions. The composition of the material of Formula (I) varies across the electrode particles by changing at least one of x, y, d, M, M′ and M″. Electrodes, cells and batteries comprising the lithium metal oxide material are also described.
