Abstract

The thickness effect on the electrochemical properties of thin-film LiCoO2 cathode has been studied. The films were prepared over a range of thickness from 1500 - 6000 Å. It was found that the diffusion coefficient of lithium ion through LiCoO2 film increased with film thickness and the rate-capability of thicker films was superior. These results were attributed to the difference of stress field caused by volume expansion during de-intercalation reaction in film electrodes with different thickness.
