Abstract

A lithium metal oxide suitable for use as a cathode material in a rechargeable battery having a general formula of: LiMM'OF, where x is 1.80<x<2.20, y=1, and more specifically 1.90<x<2.10, with 1.80<u<2.20. Preferably, 1.90<u<2.10, and 0.80<y<1.20, or more specifically, 0.90<y<1.10. The lithium metal oxide has a cation-disordered rocksalt structure, wherein M is a transition metal selected from a first group consisting of Ni, Mn, Co, Fe, and combinations thereof. M′ is a transition metal selected from a second group consisting of Ti, Zr, Nb, Mo, Sn, Hf, Te, Sb, and combinations thereof. M has a first oxidation state q and M′ has a second oxidation state q′, with (q/z)+(q′/z′)=+3, preferably +2.7≤q/z)+(q′/z′)≤+3.3.
