Thermal Charging Supercapacitors Based on Graphene Films.

ABSTRACT: Utilizing supercapacitors to convert low-grade heat into electrical energy for storage is an efficient waste heat recovery technology. In this study, the graphene films with a hierarchical porous structure are prepared, and a thermal charging supercapacitor is designed using RGO films as the electrode material. Under the influence of varying temperature fields, a different potential is induced on the working electrode and reference electrode surface of the supercapacitor, resulting in a potential difference U _out between them. The balanced voltage U _s of the supercapacitor increases linearly with the increase of the temperature difference ΔT and grows with the rise in solution concentration. The thermoelectric coefficient of the supercapacitor wit
