A long cycle-life has been obtained with an Li/LiClO4-propylene carbonate (PC)/polypyrrole (PPy) battery when a PPy film formed in LiPF6/PC by electro-oxidative polymerization is used in an LiClO4/PC electrolyte after undoping PF6- anions. The apparent diffusion coefficients of anions within the PPy film and the impedance spectra for PPy film electrodes are strongly dependent upon the film formation conditions. Electrolyte anions used in the film formation, which influence the morphology of the polymer film, have been found to play an important role in determining the electrochemical process and the cycle life of the Li/PPy battery.
