摘　　要：超级电容器即电化学电容器,是近年来发展起来的一种新型储能元件,通过离子吸附(双电层电容)或氧化还原法拉第反应(赝电容)导致电荷在电极中的储存,电荷储存机理和纳米材料的快速发展使得超级电容器的性能得到显著提高。介绍了近些年超级电容器电极材料的研究进展,从炭素材料、过渡金属氧化物和导电聚合物这3类基础材料出发,结合纳米技术并由此制得的纳米材料,综合分析了高性能超级电容器及其电极材料的发展趋势。Supercapacitors, also called electrochemical capacitors, are newly power devices that have developed rapidly in recent years. They store energy by using either ion adsorption （electrochemical double layer capacitors） or fast surface redox reactions （pseudo-capacitors）. A notable improvement in performance has been achieved through recent advances in understanding charge storage mechanism and the development of advanced nanostructured materials. In this article, the progress of elec- trode material research for supercapacitors was introduced. Beginning with the three basic material including carbon materials, transition-metal oxides and conducting polymer, and combining with the newest nano-technology and its obtained nano-materials, the development trends of supercapacitors with high energy density and its material were analyzed.
