Abstract Composite of nickel hydroxide/reduced graphene oxide (Ni(OH)2/RGO) was synthesized by facile chemical precipitation-reflux method with graphite oxide and nickel sulfate hexahydrate as precursors and ammonium hydroxide as the precipitator. The surface morphology and microscopic structures of the composite were characterized by X-ray diffraction (XRD) and scan electron microscopy (SEM). The electrochemical performance of the composite was assessed by cyclic voltammetry (CV), galvanostatic charge/discharge and electrochemical impedance spectroscopy (EIS). The influence of different mass ratio of graphite oxide to nickel hydroxide (GO: Ni(OH)2) and the concentration of ammonium hydroxide on structures, morphologies, and electrochemical properties of the composite was investigated. The results show that the synthesized composite of β-Ni(OH)2/RGO has mutually inserted structure. The composite of β-Ni(OH)2/RGO exhibits high electrochemical performance of 334.9 mAh/g at 0.2C rate and 260.2 mAh/g at 5C rate when the concentration of ammonium hydroxide is 3 mol/L and the mass ratio of GO:Ni(OH)2 is 1:8, while the product can still maintain 90% of the theoretical specific capacity of β-Ni(OH)2. It displays that this electrode material has excellent electrochemical performance with excellent rate capability.
