Abstract

Viologens, either as anions in solution or as pendant substituents to pyrrole, were incorporated as dopants to electrodeposited films of polypyrrole. The resulting polymer films exhibited redox activity at -0.5 V vs Ag/AgCl. The film consisting of polypyrrole with pendant viologens exhibited the best charge-discharge behavior with a maximum capacity of 55 mAh/g at a discharge current of 0.25 mA/cm². An anode consisting of polypyrrole (pPy) doped with viologen (V) was coupled to a cathode consisting of pPy doped with 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) to yield a polymer-based battery with a cell electromotive force (emf) of 1.0 V, maximum capacity of 16 mAh/g, and energy density of 15 Wh/kg.
