系统研究了添加Ａｌ的贮氢电极合金在高温下的电化学性能．结果表明：以Ａｌ部分替代稀土系贮氢合金中的Ｎｉ，使氢化物电极的平衡分解压降低，使高温下的放电容量升高，自放电降低、改善高倍率放电性能和循环稳定性．
The electrochemical performance of Al-added hydrogen storage electrode alloys at high temperature was systematically investigated. The results show that Al substitution of Ni in rare earth hydrogen storage alloy can reduce the equilibrium decomposition pressure of the hydride electrode, increase the discharge capacity at high temperature, decrease self-discharge, and improve high rate discharge performance and cycle stability.
