Facile electrodeposition of reduced graphene oxide hydrogels for high-performance supercapacitors†
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.
