摘要: 非对称超级电容器(ASCs)因电化学性能更为优异而成为近几年来的研究热点,石墨烯作为一种新颖的二维碳材料,具有比表面积大、导电性高、力学性能好和化学稳定性优异等优点,是非对称超级电容器复合电极的一类理想载体材料。本文综述了近几年来石墨烯基复合电极在非对称超级电容器中的应用状况,认为比表面积更大、导电性更好的石墨烯将会促进石墨烯基复合电极在超级电容器中的应用与发展,也会提高石墨烯基非对称超级电容器的性能。指出将金属氧化物、导电聚合物、金属氢氧化物以及金属硫化物纳米化,使之兼具大的有效面积、丰富的氧化还原活性位点等特点,从而提高复合材料的比电容,是石墨烯基复合电极的研究重点。

Abstract: Asymmetric supercapacitors(ASCs)have become a research hotspot in recent years owing to their outstanding electrochemical performances. Graphene,a novel two-dimensional carbon material,has many advantages such as large specific surface area,high conductivity,good mechanical property and excellent chemical stability,and thus is considered as an ideal carrier material for composite electrodes in asymmetric supercapacitors. In this paper,the status and perspective of graphene-based composite electrodes for asymmetric supercapacitors are reviewed. It is believed that the preparation of graphene with larger surface area and better electrical conductivity will be helpful to promote the application and development of graphene-based composite electrodes and to improve the performance of graphene-based supercapacitors. Finally,the trend of graphene-based composite electrodes in asymmetric supercapacitors is also briefly highlighted.

Key words: graphene, nanostructure, composites, asymmetric supercapacitors, energy density, power density
