Abstract
In this research, We reported a novel and facile approach to fabricate rGO nanosheet arrays on 3D porous nickel foam. A graphene layer with the sharp edges and wrinkles was obtained on nickel foam by an electrophoretic deposition (EPD).The fabricated electrodes were characterized using scanning electron microscope(FE-SEM).The GO sheets on the nickel foam was annealed at 300 ̊C, 600 ̊C and 900 ̊C for 4 h under flow of Ar. The electrochemical activities of supercapacitors were assessed using cyclic voltammetry (CV) and charge-discharge measurements. A maximum specific capacitance of the Go annealed at 900 ̊C can reach up to 148Fg-1 at a scan rate of 5mVs-1, which is higher than Go annealed at 600 ̊C (115Fg-1), Go annealed at 300 ̊C (72Fg-1) and Go (52Fg-1). The supercapacitor based on a GO with 900 ͦC of annealing temperature showed long cycling stability with 96.1% of capacitance retention after 200 cycles.
