Structural and morphological analyses reveal uniform growth of Co(OH) 2 microflakes with an average flake width of similar to 30 nm on the MGF surface. Moreover, electrochemical capacitive measurements of the Co(OH) 2/MGF electrode exhibit a high specific capacitance of similar to 1030 F g(-1) with similar to 37 W h kg(-1) energy and similar to 18 kW kg(-1) power density at 9.09 A g(-1) current density. The superior pseudoelectrochemical properties of cobalt hydroxide are synergistically decorated with high surface area offered by a conducting, porous 3D graphene framework, which stimulates the effective utilization of redox characteristics and mutually improves electrochemical capacitive performance with charge transport and storage. This work evokes scalable electrochemical synthesis with the enhanced supercapacitive performance of the Co(OH)(2)/MGF electrode in energy storage devices.
