摘要：

Platelet-like, flake-like, and needle-like nano-scale beta-Ni(OH)(2) particles were prepared by coordination homogeneous precipitation method in this paper. X-ray diffraction (XRD), transmission electron microscopy (TEM) and infrared absorption spectra (IR) were used to characterize the microstructure and morphology of the products. The nano-scale Ni(OH)(2) composite electrodes were prepared by mixing 10 wt.% samples with spherical Ni(OH)(2) to carry out charge-discharge test. The results show that the nano-scale Ni(OH)(2) composite electrodes have higher discharge specific capacity, and the nickel hydroxide nationeedles show a better adulteration performance than the others.
