Abstract

Electrode active materials comprising two or more groups of particles having différing chernical compositions, wherein each group of particles comprises a material selected from: (a) materials of the fonnula A1aM1b(XY4)cZd; and (b) materials of the formula A2eM2fOg; and wherein (i) A1, A2 , and A3 are Li, Na, or K; (ii) M1 and M3 comprise a transition metal; (iv) XY4 a phosphate or similar moiety; and (v) Z is OH, or halogen. In a preferred embodiment, A2eM3Og is A3hMniO4 having an inner and an outer region, wherein the inner region comprises a cubic spinel manganese oxide, and the outer region comprises a manganese oxide enriched in Mn+4 relative to the inner region. In a preferred embodiment, the compositions also comprise a basic compound.
