摘要
研究了不同ｘ值的Ｌａ１－ｘＮｄｘ（ＮｉＣｏＭｎＡｌ）５合金的晶格常数、氢平衡压力、放电容量及大电流放电性能。测定结果表明，合金晶胞体积随ｘ值增加呈线性关系减小；当ｘ＝０２时，电极容量达到最大值，而氢平衡压力最低。
The cell volume, hydrogen equilibrium pressure, discharge capacity and high rate capability of La_(1-x)Nd_x(NiCoMnAl)5 hydride storage alloys with various x were investigated. The results show that: (1) The cell volume decreases with Nd content linearly. (2) The maximum discharge capacity is achieved when x=02 and the equilibrium pressure get to minimum in the mean time, however at x=02, there is a decrease in storage capacity.
