The electrochemical properties of pristine and AlPO4-coated LiCoO2 thin films. The films were measured in the voltage range of 4.25 to 3.0V. (a) Discharge capacities of the films at current densities of 0.2, 0.4, and 0.6 mA·cm-2. Initial discharge profiles of (b) pristine and (c) AlPO4-coated films (the first cycle of Figure 2a at each current density). (d) Cyclic performances of the films at 45°C (current density was 0.4 mA·cm-2).
