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
