Graphene‐Based Materials for Supercapacitor Applications

A thick layer of carbon nanomaterial known as graphene significantly impacts the design of supercapacitors used in the production of electric devices. Since being isolated for the first time from natural graphite, graphene has received tremendous research attention. In contrast to other carbon-based materials, their high electron mobolity, two-dimensional structure, high strength, and large surface area emphasize their electrical and thermal conductivity qualities. Additionally, the most favorable conditions for supercapacitors are provided by the simple entrance of electrolytes into the graphene-based material pores and their constant pore size distribution. Given graphene's remarkable charge storage capabilities, numerous studies have investigated a broad domain of potential uses for graphene-based supercapacitor material electrodes. However, because graphene only stores energy through electrostatic adsorption and desorption processes, its drawbacks include weak capacitance and a lower energy density. This chapter deals with the feasibility of graphene-based materials as electrode materials for supercapacitor energy storage applications.
