Abstract:
We report both a facile, scalable method to prepare reduced graphene oxide hydrogels through the electrodeposition of graphene oxide and its use as an electrode for high-performance supercapacitors. Such systems exhibited specific capacitances of 147 and 223 F g(-1) at a current density of 10 A g(-1) when using H2SO4 and H2SO4 + hydroquinone redox electrolytes, respectively.
