| Abstract: | Platelet-like, flake-like, and needle-like nano-scale β-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 nanoneedles show a better adulteration performance than the others. |
