| 摘 要： | LaNi5贮氢合金在传统的贮氢应用中得到利用而被充分的研究，但LaNi5用作电池的电极太贵，不稳定，对腐蚀太敏感，而且吸放氢过程中晶胞过度膨胀和收缩，吸放氢前后体积变化率大，从而导致合金严重粉化。为了克服这些缺点，人们采用添加辅助元素部分取代基本元素的方法。即用混

| Abstract: | AB5 type complex hydrogen storage alloy was prepared by reduction-diffusion method, polymer-network gel method and coprecipitation-reduction-diffusion method, respectively. The thermo-dynamic P-C-T curve test was performed. Some electrodes of Ni-MH battery with the complex alloys was also prepared and their electrochemical properties were examined. The results indicated that there were great differences in size, morphology and properties for alloys prepared by different methods. |
