摘要
近年来,在化学电池的发展中,镍系列电池作为蓄电池占有很重要的地位,如广泛使用的Cd-Ni、MH-Ni、Zn-Ni蓄电池等.氢氧化镍是这一系列电池的主要正极活性材料,对电池的容量和寿命起着关键的作用[1].随着新一代碱性蓄电池的迅速发展,特别是随着移动式通讯设备与便携式电子计算机的飞速发展,人们对充放电电池的要求也越来越高.因此对高活性高容量镍正极材料特别是氢氧化镍的研究具有重要的现实意义.
Nickel hydroxide nanowires were prepared by hydrothermal method. The products were characterized by powder X-ray diffraction(XRD) and transmission electron microscopy(TEM). The results show that the morphology of nickel hydroxide nanowire is mainly straight. The diameters of the nanowires are about. 20-30 nm and the lengths reach several micronmeters. The effects of hydrothermal reaction time and filling factor on the morphologies and structure of the products were studied. The formation mechanism for nickel hydroxide nanowires is also discussed.
