Lithium-modified manganese oxides as materials for the positive electrode of the lithium batteiy

New phases in the Li₂O-MnO₂ system were obtained, capable of introducing lithium electrochemically at potentials about 3 V and reversibly. They possess a stable capacity on the level 70-80 mA·hour/g. Due to their low cost, simplicity of synthesis, and high cycling ability, the oxides synthesized show promise as a cathodic material for lithium-ionic batteries.
