Zusammenfassung: | Ni(OH) sub(2)/graphene foam (GF) electrode was synthesized for electrochemical application by a facile hydrothermal reflux technique. The results obtained from the scanning electron microscopy showed that the Ni(OH) sub(2) spheres successfully coated the entire surface area of the GF. Specific capacitance of 2420 F g super(-1) at a current density of 1 A g super(-1) was obtained for Ni(OH) sub(2)/GF composite electrode, as well as a capacitance retention of ~93 % after 1000 charge-discharge cycles, demonstrating excellent cycle stability in 6.0 M KOH electrolyte. These results suggest that the composite could be a potential active material for high-performance electrochemical applications. |
