Abstract

Conducting polymers that can be switched between a neutral state and a doped state are of interest for charge storage applications. We report on the fabrication of an all-polymer charge storage device incorporating derivatized polythiophene films electropolymerized onto graphite-coated polymeric supports and a polymer gel electrolyte film. The devices exhibited discharge voltages of about 2.4 and capacities of 9.5-11.5 mAh g-1. The elimination of any metallic components or liquids and the lightweight and flexible construction provides a unique approach for the fabrication of organic power sources.
