1. A lithium metal oxide having a general formula: LiaMbM′cO2, said lithium metal oxide comprising LiMO2 and LiaM′eO2, said lithium metal oxide having a cation-disordered rocksalt structure, wherein M comprises one or more of a metallic species chosen from a group consisting of Ti, V, Cr, Ni, Co, Fe, Mn, Zr, Sb, and Mo, M being chosen such that LiMO2 forms a cation-disordered rocksalt structure, and M having a first average oxidation degree n, wherein M′ comprises one or more of a metallic species chosen from a group consisting of Ti, Cr, Mn, Zr, Mo, Sn, Sb, and W, and M′ having a second average oxidation degree y greater than or equal to n, with 4<=y<=6, and wherein 1<a<=1.4, a+b+c=2, d+e=2, d+(e·y)=4, a+(b·n)+(c·y)=4,1.3<=d<=1.7,and 0.2<=b<1.
