A high charging-discharging efficiency was obtained for Li/LiClO//4-PC (propylene carbonate)/PPy (polypyrrole) battery, when a PPy film formed in LiPF//6/PC by electropolymerization was used in a LiClO//4 electrolyte after PF//6** minus anion undoping. The anion doping-undoping process for the PPy film electrodes was examined with the usual electrochemical techniques. A Li/LiClO//4/PPy cell was also tested with a constant current charging-discharging performance. The relationship between sweep rate and anodic peak current shown in the cyclic voltammograms obtained for the PPy film formed in the LiClO//4 electrolyte indicates a typical diffusion-controlled process, while a reaction-controlled process was found to be involved in the PPy film electrode formed in the LiPF//6 electrolyte.
