摘要
电容器与二次电池相比,有着显著的优点,尤其是高功率并能提供大电流的电双层(超级)电容器正是时代所需。对目前已用做电双层电容器电极材料的活性碳纤维、纳米碳管和膨胀性石墨的研究情况分别做了论述。与膨胀性石墨相比,如何发挥活性碳纤维和碳纳米管的实际电容效率是目前研究的重点。
The capacitors as compared to secondary battery have prominent advantages, especially electrical double-layer （super） capacitors with high power and large currents are presently needed. The present status of activated carbon fibers, carbon nanotubes and expansile graphites as the electrode materials for electrical double-layer capacitors were discussed respectively. The emphasis was put on how to enhance the real capacity efficiency of active carbon fibers and carbon nanotubes as compared to expanded graphite.
