| Abstract: | LiCoO2 films were fabricated on nickel substrates by a hydrothermal-electrochemical method. The film prepared at 80℃ is mainly (003) plane oriented and prepared at 100℃, (101) and (104) plane oriented and prepared at 150℃ (003) plane oriented as well. The (101) plane orientation is favorable for Li+ diffusion through the cathode, and therefore the (101) plane oriented film contributes to the enhanced electrochemical performance. The film with (101) oriented prepared at 100℃ has the capacity of 143mAh/g and no obvious capacity attenuation detected. |
