Li0.33MnO2 cathode material was synthesized by solid state reaction.The material showed a small coherent domain size about 10 nm determined by X-ray diffraction and transmission electron microscopy.The electrochemical properties of the material were studied in different potential windows of 3.5-2.0 V and 4.3-2.0 V.An irreversible transformation to spinel phase was observed in the initial several cycles,which was more prominent on the thicker spinel layer formed on the material surface.
