系统地研究了具有不同稀土成分（RE = La1−x−y−zCexNdyPrz）的RENi5−xMx（M = Co，Mn，Ti）储氢合金的电化学性能。结果表明，La、Ce、Nd、Pr对电极性能都有较大影响。使用数学方法来分析成分，结果表明所有成分对电极性能都有综合影响。采用计算机程序绘制了多元合金电极的等放电容量、等高倍率放电能力和等循环寿命与准三元稀土元素成分的等值线图。
The electrochemical properties of RENi5−xMx(M = Co, Mn, Ti) hydrogen storage alloys with different compositions of rare earth components (RE = La1−x−y−zCexNdyPrz) were systematically examined. The results showed that La, Ce, Nd and Pr all had big effects on the electrode performance. A mathematical-methodological approach to compositions was used and the results showed that all had the combined effect on the electrode properties. A computer program was adopted to draw out isographs including the isodischarge capacity, iso-high-rate dischargeability and isocycle life of multicomponent alloy electrodes vs. the composition of quasi-ternary rare earth elements.
