Abstract:
Electrochemical characteristics of an electrochemically prepared poly(3-alkylthiophene) gel and its battery characteristics have been studied. The gel film exhibited an oxidation wave in electrochemical measurements whereas the as-prepared film showed an additional peak at lower potential. Oxidation and reduction peak potentials showed marked decrease with increasing concentrations of chloroform in the electrolyte solution. These results have been explained in terms of structural disorders in the side and the main chains. Upon increasing the polymerization potential, the expansion ratio and the diffusion coefficient of dopant ion, D app , of the gel film increased. The gel film exhibited better characteristics as an electrode active material in comparison with the as-prepared film. These results of electrochemical properties of the gel film have been attributed to the effects of free volume in the gel having a three-dimensional network structure.
