Abstract

Electrochemical doping-undoping kinetics of electropolymerized polypyrrole (PPy) and the charge-discharge characteristics of Li/LiClO//4/PPy battery were found to show an interesting dependency on the kind of anions used for the preparation of PPy film. The relationship between the doping charge (anodization charge estimated from cyclic voltammogram) of PPy film and the polymerization potential revealed that the optimum potential for getting the largest doping capacity depends strongly on the kind of anions. The optimum potential for PF//6** minus - and CF//3SO//3** minus - formed PPy films was 0. 32V vs. Ag/Ag** plus . On the other hand, ClO//4** minus - formed PPy film had the largest doping charge at 0. 84V preparation over an examined potential range (0. 30-0. 84V).
