The recent progress and earnest motivation to develop high specific energy capacitors commercially for the emerging market and electronics industry, coupled with the significance and popularity of graphene foam (GF)–based electrode materials in the preparation of functional capacitors have been crucially explored in this review. The review outlines the current disposition and headways in GF-based ECs' technology. Besides, owing to its three-dimensional interconnected hierarchical form alongside the physicochemical distinctions, GF has been regarded as one to curtail some bottlenecks regarding graphene dispersion/restacking in nanocomposite materials. Some of the various techniques to synthesizing high-grade GF that can enable higher energy density of ECs, as well as some key material's features of GF that enhance various performances of the material's composite have also been reviewed.en© 2020 Elsevier B.V.
