本文初步研究了M11－xCax（Ni，Co，Al）5合金中Ca含量对金属氢化物（MH）电极的电化学性能和合金的平台压力的影响．实验结累表明随苦合金中Ca含量的增加。活化性能得到改善．但是电极的充放电循环稳定性却下降，特别当X≥0．2时、电极的循环稳定性明显下降．在x＝0．1时．合金电极具有最大的电化学放电容量331mAh·g－1（C／3，在1C，2C倍率放电条件下、x=0．1和x＝0．2的合金电极具有较好的高倍率放电性能．在x＜0．3时，合金的平台压力随着x值的增加而上升，但x＝0．4的合金平台压力比2＝0．3的合金平台压力略有降低
In this paper, the effect of Ca content in M11-xCax (Ni, Co, Al) 5 alloy on the electrochemical performance of metal hydride (MH) electrode and the plateau pressure of the alloy was investigated. Experimental results show that with the increase of Ca content in the alloy. Activation performance is improved. However, the charge-discharge cycle stability of the electrode is decreased, especially when X≥0.2, the cycle stability of the electrode is obviously decreased. At x = 0.1. The alloy electrode has a maximum electrochemical discharge capacity of 331mAh · g-1 (C / 3, at 1C, 2C rate discharge conditions, x = 0.1 and x = 0.2 alloy electrode has better high rate discharge performance At x <0.3, the plateau pressure of alloy increased with the increase of x value, but the alloy plateau pressure of x = 0.4 was slightly lower than the alloy plateau pressure of 2 = 0.3
