采用循环伏安法在草酸溶液中以200 mV/s的扫描速率电沉积在钛箔上制备了用于氧化还原超级电容器的高活性聚吡咯电极，随后在1 M KCl中进行了表征。扫描电子显微镜显示聚吡咯具有高度多孔的纳米结构，导致约480 +/-50F/g的非常高的比电容。电极在循环寿命测试中表现出较高的稳定性。研究了聚吡咯电极材料质量对比电容的影响。(C)2006 Elsevier B. V.保留所有权利。
Highly active polypyrrole electrodes for redox supercapacitors were prepared by electrodeposition on Ti foil via cyclic voltammetry at a scan rate of 200 mV/s in oxalic acid solution and subsequently characterized in 1 M KCl. Scanning electron microscopy showed that the polypyrrole has a highly porous nanostructure leading to a very high specific capacitance of about 480 +/- 50 F/g. The electrode exhibted a high stability during cycle life test. The effects of the mass of polypyrrole electrode materials on the specific capacitance were also investigated. (C) 2006 Elsevier B.V.
