Abstract

In this work, pulsed laser deposition (PLD) was used to grow LiCoO₂ films and the effect of the deposition conditions, on the structure and morphology of LiCoO₂ films was investigated. The results showed that the surface roughness of LiCoO₂ films can be reduced by decreasing the laser power to a certain degree and the crystallinity of LiCoO₂ films can be improved by elevating the annealing temperature and increasing the oxygen pressure although layered LiCoO₂ films can be obtained by in-situ annealing at as low as 400°C. The LiCoO₂ films under the optimized deposition condition have good electrochemnical reversibility with an initial discharge capacity of 36μAh/(μim·cm) and a cycling efficiency of 94.44%.
