| 摘 要： | 利用交流阻抗、循环伏安及扫描电镜（ＳＥＭ）观察等方法，测定了ＭＬＮｉ４和ＭＬＮｉ４Ｓｉ（ＭＬ：富镧混合稀土金属）贮氢电极的性能，并对两电极性能差别的原因进行了分析和讨论．结果表明，ＭＬＮｉ４Ｃｒ电极比ＭＬＮｉ４Ｓｉ电极易活化、放电容量大、过电位小以及快速放电能力强；而ＭＬＮｉ４Ｓｉ电极具有较好的循环充放电特性．

| Abstract: | The properties of MLNi4Cr and MLNl4Si hydrogen storage electrodes are studied in this paper.Their property diffcrences have been analysed by a.c.impedance,cyclic voltammetry and SEM methods.The results show that MLNl4Cr electrode has higher discharge potential,better fast discharge ability and lower discharge overpotential.However,MLNi4Si electrode display longer charge-discharge cycle life. |
