We composed rechargeable Li polymer battery of PES/PEO electrolyte films, PPy cathode and Li metal anode without any low molecular weight plasticizer or solvent and systematically investigated the effect of dopant and polymerization rate of PPy on the electrochemical behavior and battery performances. Cyclic voltammograms of Li/PPy cells indicated that the improvement of doping-dedoping kinetics of PPy doped with DS anion may be due to the fast movement of Li cation through porous PPy film because the bulky surfactant anion (DS anion) was immobilized in PPy chain during redox process. AFM surface images of PPy films suggested that the better charging-discharging properties of Li/PPy cell using PPy polymerized in slow reaction condition result from the increase in the effective interfacial area between PPy and polymer electrolyte.
