Abstract
研究了以Ce部分取代La对AB3型储氢合金La0.7-xCexMg0.3Ni2.4Co0.6(x=0~0.4)结构和电化学性能的影响.实验表明,该系列合金主要包含LaNi3相和LaNi5相.随着Ce含量的增加,合金电极的最大放电容量逐渐降低,但循环稳定性得到了明显改善.
 
The effect of partial substitution of Ce for La on the structure and the electrochemical properties of the La0.7-xCexMg0.3Ni2.4Co0.6(x=0~0.4)hydrogen storage alloys have been investigated systematically.The result of X-ray powder diffraction(XRD) show that the alloys are all consisted of the LaNi3 phase and the LaNi5 phase.The maximum discharge capacity is decreased gradually with increase of the Ce contents,but the cycling life is improved obviously.
