Graphene Nanosheet

A homogeneous Ni (OH)2/graphene nanosheet (GNS) nanocomposite with excellent supercapacitive performance has been synthesized by a facile chemical precipitation. The Ni (OH)2/GNS nanocomposite presented an ideal morphology with the nanosized Ni (OH)2 particles homogeneously growing on the GNS. Its microstructure, morphology were investigated by XRD, SEM and TEM. The electrochemical performance of the Ni (OH)2/GNS nanocomposite was test by cyclic voltammetry, galvanostatic charge−discharge and electrochemical impedance spectroscopy techniques. The homogeneous Ni (OH)2/GNS nanocomposite exhibited a high specific capacitance of 1667 F/g at a current density of 1A/g and maintained a good stability in 5000 cycles, suggesting that it can be a promising candidate for supercapacitor. The high specific capacitance and remarkable rate capability are promising for applications in supercapacitors with both high energy and power densities. The Ni (OH)2/GNS nanocomposite exhibited large specific capacitance, high rate capability and good cycling stability.
