发展中的电化学电容器

Electrochemical capacitors in developing

详述了电化学电容器的特点:可高倍率充放电,充放循环寿命远大于可充电电池,它在充放电过程中产生的热效应小于电池充放电过程中产生的热效应。讨论了各种类型的电化学电容器:双电层电容器、吸附作用产生的准电容、混合电化学电容器、导电聚合物氧化还原超电容器和复合电极电化学电容器。阐述了超级电容器的各种应用;指出它是具有发展前景的一种能量贮存利用装置。

In this paper, the characteristics of electrochemical capacitors were described in details. Compared to rechargeable batteries, electrochemical capacitors have capability of high rate charge/ discharge and much longer cycle life, The heat effects in the process of charge/discharge cycle of supercapacitors are less than that of the reclargeable batteries. The various electrochemical capacitors, which included the electric double layer capacitor, adsorption pseudocapacitors, asymmetric electrochemical capacitors, conducting polymer redox supercapacitors and hybrid electrochemical capacitors, were discussed, The different applications of supercapacitors were also described. It was pointed out that the electrochemical capacitors were energy storage devices with bright orosoects,
