Discharge capacities, cyclic performances, and discharge profiles of the thin films. (a) Discharge capacities and cyclic performances of pristine and fluoride-coated LiCoO2 thin films, (b) discharge profile of the pristine film, (c) discharge profile of the AlF3-coated film, and (d) discharge profile of the LaF3-coated film. (The voltage was in the range of 4.25 to 3.0 V, and the current densities were 0.2, 0.4, and 0.6 mA· cm-2.).
