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