用导电聚合物电极的超电容器研究概况

Super capacitors of conductive polymer electrodes.

导电聚合物制备电极的超电容器（Ｓｕｐｅｒｃａｐａｃｉｔｏｒｓ） 有两种类型： 导电聚合物直接制备电极和导电聚合物高温热解为硬碳（Ｈａｒｄ ｃａｒｂｏｎ）制备电极的电容器。导电聚合物超电容器基于法拉第准电容（Ｆａｒａｄａｉｃｐｓｅｕ－ｄｏｃａｐａｃｉｔａｎｃｅ） 原理， 进出正极的是阴离子， 进出负极的是阳离子。该电容器结构中一个电极是ｎ 型掺杂， 另一个是ｐ 型掺杂。聚合物超电容器的能量密度比活性碳作电极的双电层电容器大２～３倍，

ELECTRONIC COMPONENTS & MATERIALS (China) ,Vol.18,No.5,P.42 44(Oct.1999).In Chinese. There are two kinds of super capacitors of conductive polymer electrodes.One has the electrodes made directly from conductive polymer;the other has the electrodes made from hard carbon acquired by thermal decomposition of conductive polymer.The capacitors are based on the principle of faradic pseudo capacitance.Anions go through the positive electrodes and basic ions through the negative electrodes.The capacitance of the capacitors is 2～3 times as high as that of doublelayer capacitors.(11 refs.)
