摘要：

Thin films of Li4Ti5O12 and LiCoO2 were prepared from precursors obtained by a sol-gel process using poly(vinylpyrrolidone) (PVP) followed by a heat treatment at 600-800 degreesC. Both thin films were characterized with X-ray diffraction method and cyclic voltammetry (CV). The Li4Ti5O12 and LiCoO2 thin films have spinel structure and layered rock salt structure, respectively. Their crystallinity was comparable with those for highly crystallized samples. The thickness of both films was about 1 mum after three times of the sol-gel process followed by the heat treatment. An orientation of the thin films was observed. The electrochemical characteristics for both films were comparable with those for standard powder samples.
