Three dimensional graphene networks （3DGNs） are promising electrode materials in electrochemical applications be-cause they provide short diffusion pathways for electrolyte ions and fast transport channels for electrons, and act as an ideal scaffold for forming composites with pseudocapacitive materials to obtain a synergistic effect. This review offers an overview of recent ad-vances in the synthesis of 3DGNs and their composites as electrodes in supercapacitors. In particular, methods to enhance the capaci-tive performance of 3DGN-based supercapacitors are summarized. Prospects for the future development of 3DGNs are presented at the end.
