Progress of Research on Electrode Materials for Electrochemical Supercapacitors

Electrochemical supercapacitors have been focused for their great capacitance, fast charging-discharging with big current, and very long cycle life since they were born. In recent years, with their applications in national security science technology, environmental reservation and so on, the studies on them have become one of the hot spots in the strategic field. In this paper, the authors outlined the recent progress of research on electrode material for the electrochemical supercapacitors and classed them into four kinds: carbon materials series, transition metal oxides series, electronically conducting organic polymers series and others. At the same time, the authors analyzed the development orientations of the four kinds of electrode materials and brought out the research emphasis of the four kinds of electrochemical supercapacitors electrode materials in future.
