In this paper, a composite material, Ni0.37Co 0.63(OH)2, is synthesized using the chemical precipitation method with the purpose to develop electrode materials for supercapacitors. Physical characterization using XRD, EDX, and SEM show that Ni 0.37Co0.63(OH)2 possesses an amorphous structure, which leads to high specific capacitance of 1840 F g-1 in the potential window of 0-1.5 V. Cyclic voltammetry methods are employed to characterize the electrochemical properties of this electrode material in a N2-saturated alkaline solution. The results demonstrate that this material could give a two-elec...
