Abstract

<jats:title>Abstract</jats:title> <jats:p>Lithium-manganese-cobalt oxide, Li(Lix/3MN2x/3Co1−x)O2 (0 ≤ x ≤ 1) was prepared as a solid solution between the two kinds of layer structured end members, LiCoO2 and Li2MnO3. 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.</jats:p>
