Lithium-manganese-cobalt oxide, Li(Li<SUB>x/3</SUB>MN<SUB>2x/3</SUB>Co<SUB>1−x</SUB>)O<SUB>2</SUB> (0 ≤ x ≤ 1) was prepared as a solid solution between the two kinds of layer structured end members, LiCoO<SUB>2</SUB> and Li<SUB>2</SUB>MnO<SUB>3</SUB>. Excess lithium carbonate or lithium hydroxide should be added to the mixture on calcination at 900 - 1000 °C to obtain the solid solutions. The resulting layer structured solid solutions can be used as a cathode material for secondary lithium batteries.
