中文摘要	采用化学氧化聚和法制备了聚苯胺电极材料,所制备的聚苯胺具有高于420F/g的法拉第赝电容和良好的电化学特性.分别采用聚苯胺作为正极材料,高比容量活性碳作为负极,38%硫酸作为电解液制备了复合型电化学电容器.复合型电容器工作电压达到1.4V,最大电容器比容量达到57F/g,最大比能量达到15.5Wh/kg.电容器200mA/cm2放电条件下真实功率达到2.8W/g,峰值比功率达到20.4W/g.循环工作寿命超过1000次.; The performance of a newly designed, polyaniline activated carbon, hybrid electrochemical capacitor was evaluated. The polyaniline was prepared by the chemical oxidation/polymerization process. The capacitor was assembled by using polyaniline as a positive electrode and an activated carbon as a negative electrode respectively. From a cyclic voltammograms test, a specific capacitance of 420 F/g was obtained for polyaniline electrode. The cycle life of the cell is proved to be more than 1000 times by the Galvanostatic charge and discharge test. Values for the specific energy and real specific power of 15.5 Wh/kg and 2.8 W/g, respectively, are demonstrated for a cell voltage between 0.0 and 1.4 V. The max specific power for the hybrid capacitor amounts to 20.4 W/g.
