摘　　要：三维石墨烯具有独特的三维多孔结构,不仅增加了与电解液的接触面积,同时为固定在其表面的活性物质提供了快速的电子传输通道,有效地提高了超级电容器的电化学性能,使其被认为是最有前景的超级电容器电极材料。综述了目前获得多孔结构、大比表面积、优异导电性和良好力学性能的三维石墨烯的方法,并简述了其复合材料在超级电容器领域的应用现状。The porous structure of three-dimensional graphene not only improves the contact area with the electrolyte but also provides a fast electron transport channels for the active materials anchored on it, therefore the electrochemical performance of the supercapaeitors can be effectively enhanced, which makes them to be the promising materials for supercapacitors. This review summarizes the preparation methods of the three-dimensional graphene with a porous structure, large specific surface area, good electrical conductivity and excellent mechanical properties, in addition, the application status of the three-dimensional graphene composites in supercapacitors is described.
