摘要：

Copper-doped nickel hydroxide (Cu:Ni(OH)(2)) was synthesized via a facile wet-chemical method and its structural and electrochemical properties were compared to those of pure nickel hydroxide (Ni(OH)(2)). After Cu incorporation, the morphology of the Ni(OH)(2) nanostructures could be easily tuned from a curved nanolayered structure to a nanolayer-stacking structure. Both samples were hydrophilic. Furthermore, even though no additional conductive and binder materials were employed, the Cu:Ni(OH)(2) sample exhibited better pseudocapacitance performance than the Ni(OH)(2) sample. These results confirmed that the Cu:Ni(OH)(2) sample, which can be prepared by an easy low-cost method, shows great potential for application in electrochemical devices.
