摘要
超电容器具有能量密度高,循环寿命长,可大功率充放电等特性,应用前景诱人。导电性聚合物由于可取得较高的容量和价格低廉,是合适的超电容器电极材料。采用不同掺杂方式的导电性聚合物(N型或P型)作为电极材料使相应的超电容器分为三种类型,各具有不同的工作电压及容量特性。笔者综述了聚合物超电容器的工作原理和最新研究进展。
Conductive polymers are ideal materials for use in electrochemical capacitors because of their high capacitive energy density and low cost. Electrochemical capacitors can be classified into three types by their electrodes of different polymer materials. The materials possess different working voltage and capacitance characteristics because of the different doping methods (N or P). The principle and the update research achievements are reviewed.
