Raman spectrum of the 3D graphene foam. In order to obtain high performance of supercapacitor electrode materials, the electrochemical performance of the 3D graphene foam was tested, including cyclic voltammetry (CV), galvanostatic charge-discharge and electrochemical impedance spectroscopy (EIS) in a three electrode system.
Tang et al. ultrasonically dispersed reduced graphene oxide (rGO) and CNTs and then filtered them into membranes to form electrodes, it was found that the specific capacitance of the electrode can reach to 201 F/g in organic solvent electrolyte.
Zhang et al. have developed a nitrogen-superdoped 3D graphene network structure that exhibits exceptional electrochemical performance due to the synergistic interaction between a highly conductive graphene foam and a nitrogen-superdoped reduced graphene oxide aerogel.
Ruoff et al. used the chemically modified graphene obtained by reduction method and assembled it into a supercapacitor, the specific capacitance can reach 135 F/g in aqueous electrolyte, which is much lower than the theoretical specific capacitance of graphene .
