Application of Graphenes in Supercapacitors: A Review

This review investigated the literature, mainly of recent years, on the current topic of using graphenes in supercapacitors. The effects of the graphene porous structure, doping, and irradiation are considered. Methods for producing graphenes, composites of graphenes with metal oxides, sulfides, and selenides, metal particles, electron-conducting polymers, MXenes, as well as quantum dots, are considered. Electrochemical characteristics are given for the considered graphene types.
