摘　　要： 介绍了电化学电容器的工作原理,着重阐述了纳米多孔碳材料的电荷存储机制,指出碳材料的比容量与其比表面积并非线性相关,碳材料比表面积的实际利用率取决于碳孔径大小和电解质溶液离子粒径的关联度。综述了电化学电容器各类电极材料的研究进展,如多孔碳、碳纳米管、石墨烯、过渡金属氧化物以及导电聚合物,并展望了电化学电容器的应用前景。 The working principles of electrochemical capacitors are reviewed, and charge storage mechanisms of the nanoporous carbons are emphasized. There is no simple linear relationship between the surface area and the capaci- tance. However, the real utilization ratio of carbon surface area depends on the relationship between carbon pore size and electrolyte ion size. The research achievements of electrode materials, such as porous carbon, carbon nanotubes, graphene, transition metal oxide and conductive polymer, are discussed. The application prospects of electrochemical capacitors are put forward.
