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/cm(2). 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.
作为聚吡咯电沉积膜的掺杂剂，不论是在溶液中作为阴离子还是作为取代基的联吡啶，都被引入其中。所得聚合物膜在相对于 Ag/AgCl 为-0.5 V 时表现出氧化还原活性。由带有联吡啶侧基的聚吡咯组成的薄膜具有最佳的充放电性能，在 0.25 mA/cm(2) 的放电电流下，最大容量为 55 mAh/g。由聚吡咯（pPy）掺杂联吡啶（V）组成的阳极与由聚吡咯（pPy）掺杂 2,2'-联氮双（3-乙基苯并噻唑啉-6-磺酸）（ABTS）组成的阴极相结合，生成一种聚合物基电池，其电池电动势（emf）为 1.0 V，最大容量为 16 mAh/g，能量密度为 15 Wh/kg。
