A comparison between transient energy storage systems based on a gelatin composite with graphene flakes and graphene oxide layers has been done. Energy storage devices, based on the proposed new materials have higher values of the surface capacitance than those measured for energy storage devices based on activated carbon. As evidenced, both the composites enable the realization of energy sources that can supply a stable bias voltage in time. The biopolymer acts both as solid electrolyte and as binder for holding together the filler and the water-glycerol molecules. In addition, the use of the graphene oxide as filler within the gelatin matrix leads to a major increase of the mechanical stability of the prepared blends.

Abstract

A comparison between transient energy storage systems based on a gelatin composite with graphene flakes and graphene oxide layers has been done. Energy storage devices, based on the proposed new materials have higher values of the surface capacitance than those measured for energy storage devices based on activated carbon. As evidenced, both the composites enable the realization of energy sources that can supply a stable bias voltage in time. The biopolymer acts both as solid electrolyte and as binder for holding together the filler and the water-glycerol molecules. In addition, the use of the graphene oxide as filler within the gelatin matrix leads to a major increase of the mechanical stability of the prepared blends.
