1. A lithium metal oxide electrode material comprising a disordered rock salt structure with partial lithiated-spinel character, wherein the material has a formula Li2(M″2-aM′a)O4; wherein M″ comprises Co; M′″ comprises one or more metals selected from the group consisting of Al, Mg and Ti; 0<a≤0.5; and the material of formula Li2(M″2-aM′″a)O4 has the crystallographic formula: [Li2-bM′″b]16c[M″2-aM′a-bLib]16dO4, wherein 16c and 16d refer to the octahedral sites of the prototypic space group symmetry Fd3m, and 0<b<0.5.
