摘　　要：本文综述了超级电容器电极材料碳纳米管/石墨烯复合结构的制备方法,以及由该结构和赝电容活性物质形成的三元复合体系的电化学电容行为研究进展,并提出合理设计的碳纳米管和石墨烯复合结构可以有效发挥其高电导率、高比表面积和合理孔隙结构的优势,实现活性物质的高密度负载,从而获得具有高容量、良好倍率特性和长寿命的电化学超级电容器电极材料。In this paper, we review the preparation methods of carbon nanotube （CNT）/graphene composite materials for the electrode of supercapacitors, and introduce the developments of CNT/graphene/pseudo- capacitive material ternary composite materials with highly electrochemical performance. The rational designed CNT/graphene composite nanostructures could largely utilize the characteristics of carbon nanomaterials for electrochemical double-large supercapacitors, such as large specific area, high conductivity and befitting porous structure, and also achieve large mass loading of pseudo-capacitive materials with high dispersion for pseudo- capacitors. As a result, these composite materials are promising candidates for the electrode materials of high- performance supercapacitors with high capacitance, excellent rate performance and long lifetime.
