  • Abstract The main goal of this research is to use the simple chemical co-deposition method to make up Ni(OH)2, and then formulate the Ni(OH)2 electrode by electro-phoresis method, and finally discuss the effect of calcining temperature and time on the electro-chemical properties.
      Besides, we integrate the carbon nanoflakes (CNFs) to produce the Ni(OH)2/CNFs compound electrodes to enhance the capacitance performance of Ni(OH)2 electrodes. After the electro-phoresis process, the NiO could be obtained by high-temperature calcined the Ni(OH)2 gel prepared by chemical co-deposition method. From the XRD analysis, the results show that the phase of Ni(OH)2 could be transformed after the calcining temperature of 300℃. The reaction is Ni(OH)2 changed to NiO and H2O.
      From the SEM images, the surface morphology of NiO shows the plate structure, which is different from the general ball structure, after the calcining process. The capacitance performance measured by cycling CV method shows that the optimal performance could be obtained when the calcing temperature from Ni(OH)2 to NiO was about 300℃. The characteristic peaks of oxidation and reduction of NiO were about 0.45 and 0.35V, respectively. The measured capacitance was about 26Fg-1
    The experimental esults show that the composite electrodes with the CNFs could apparently improve the electro-chemical performance of the NiO.
