摘　　要：石墨烯气凝胶是以二维的石墨烯片层相互搭接形成的具有三维网络交联结构的多孔材料,结合了石墨烯及气凝胶的优点。基于溶胶-凝胶法将氧化石墨烯溶液组装成为石墨烯气凝胶的制备过程简便、可操作性强、成本较低且易于改性,因而备受关注。The graphene aerogel is a kind of porous material with interconnected three-dimensional network, formed by overlapping two-dimensional graphene sheets. The graphene aerogel combines the advantages of graphene and aerogels. The assembling process of the graphene aerogel from graphene oxide solution, based on sol-gel method is simple, feasible, low cost and easy to be modified. Based on the sol-gel method, the preparation of graphene aerogels and its application in the field of energy storage were reviewed, and the research direction of electrochemical performance of modified graphene gasgel based on sol-gel method was also prospected.
