Stabilized layered lithium metal oxide cathode materials are described which include excess lithium, Ni, Mn, and at least one other metal ion. The materials comprise a layered LiMO₂-type material in which M comprises a combination of Ni, Mn, and at least one other metal ion that includes less than about 6 mol % Co; and which has about 1 to 6 percent excess lithium. In one embodiment, the stabilized lithium metal oxide cathode material comprises a composition having the empirical formula xLi₂MnO₃·(1−x)LiNi_0.5+δ/2Mn_0.5−δCo_δ/2O₂, wherein 01+3y[Ni_aMn_bM′_c]_1−yO₂, wherein M′ is one of more metal selected from the group consisting of Co, Al, Fe, Mg, and Ti; 0
