Three-dimensional (3D) graphene-based hydrogels have attracted great interest for applying in supercapcacitors electrodes, owing to their intriguing properties that combine the structural interconnectivities and the outstanding properties of graphene. However, the pristine graphene hydrogel can not satisfy the high-performance demands, especial in high specific capacitance. Consequently, novel graphene-based composite hydrogels with increased electrochemical properties have been developed. In this mini review, a brief summary of recent progress in the research of the three-dimensional graphene-based composite hydrogel for flexible supercapacitors electrodes materials is presented. The latest progress in the graphene-based composite hydrogel consisting of graphene/metal, graphene/polymer, and atoms doped graphene is discussed. Furthermore, future perspectives and challenges in graphene-based composite hydrogel for supercapacitor electrodes are also expressed.
基于三维（3D）石墨烯的水凝胶因其兼具石墨烯的结构互连性和出色性能的有趣特性，在超级电容器电极应用方面引起了极大关注。然而，原始的石墨烯水凝胶无法满足高性能需求，尤其是在高比电容方面。因此，已开发出具有增强电化学性能的新型基于石墨烯的复合水凝胶。在本综述中，简要总结了用于柔性超级电容器电极材料的三维基于石墨烯的复合水凝胶研究的最新进展。讨论了由石墨烯/金属、石墨烯/聚合物和原子掺杂石墨烯组成的基于石墨烯的复合水凝胶的最新进展。此外，还阐述了基于石墨烯的复合水凝胶用于超级电容器电极的未来前景和挑战。
