A homogeneous Ni (OH)2/ carbon nanotubes (CNTs) nanocomposite with excellent supercapacitive performance has been synthesized via a facile chemical precipitation. The microstructure and morphology of Ni (OH)2/CNTs nanocomposite were investigated by XRD, SEM and TEM. It presented an ideal morphology with the nanosized Ni (OH)2 particles homogeneously growing on the CNTs. The electrochemical performance of the Ni (OH)2/CNTs nanocomposite was test by cyclic voltammetry, galvanostatic charge−discharge and electrochemical impedance spectroscopy techniques. The synthesized Ni (OH)2/CNTs nanocomposite shows superior electrochemical performance, including high capacitance, excellent rate capability and good cycle life. The homogeneous Ni (OH)2/ CNTs nanocomposite exhibited a high specific capacitance of 1741 F g-1 at a current density of 1A g-1 and maintained a good stability after 5000 cycles at 10A g-1`, suggesting that it can be a promising candidate for supercapacitor.

Supercapacitor Electrode Materials

Cauliflower-like Co3O4/three-dimensional (3D) graphene nanocomposite material was synthesized by a facile two-step synthesis route (heat reduction of graphite oxide (GO) and hydrothermal synthesis of Co3O4). The phase composition, morphology, and structure of the as-obtained products were characterized by scanning electron microscopy (SEM), transmission electron microscope (TEM), and X-ray diffraction (XRD). Electrochemical properties as supercapacitor electrode materials were systematically investigated by cyclic voltammetry (CV) and constant current charge-discharge tests. It was found that the Co3O4/3D graphene composite showed a maximum specific capacitance of 863 F g−1, which was obtained by means of CVs at a scan rate of 1 mV s−1in 6 M KOH aqueous solution. Moreover, the composite exhibited improved cycling stability after 1,000 cycles. The good supercapacitor performance is ascribed to the combination of 3D graphene and cauliflower-like Co3O4, which leads to a strong synergistic effect to remarkably boost the utilization ratio of Co3O4and graphene for high capacitance.
