La1-xCex(NiCoMnAl)5.05(x = 0, 0.25, 0.50, 0.75) series alloy is prepared by induction melting method; the PCT gaseous hydrogen absorption and desorption test is also carried out. The results show, with the increase of Ce substitution amount, the unit cell volume of alloy decreases gradually, and the axial ratio c/a increases gradually; with the increase of substitution amount, the discharge capacity of alloy decreases gradually, and its high rate discharge performance firstly increases and then decreases, and the discharge performance of alloy at x = 0.25 is the best; the cycle life of alloy is gradually improved with the increase of Ce substitution; with the increase of substitution amount, the maximum hydrogen absorption of alloy decreases gradually, but hydrogen desorption plateau pressure increases gradually.

采用感应熔炼法制备了La1-xCex(NiCoMnAl)5.05(x = 0,0.25,0.50,0.75)系列合金,并对其进行了PCT气态吸放氢测试。结果表明,随着Ce替代量的增加,合金的晶胞体积逐渐减小,轴比c/a逐渐增大;随替代量的增加合金的放电容量逐渐降低,其高倍率放电性能先提高后降低,x = 0.25时合金的倍率放电性能最好;而合金的循环寿命随Ce替代量的增加而逐渐提高;随替代量的增加合金的最大吸氢量逐渐减小,但其放氢平台压力却逐渐提高。

采用感应熔炼法制备了La1-xCex(NiCoMnAl)5.05(x = 0,0.25,0.50,0.75)系列合金,并对其进行了PCT气态吸放氢测试。结果表明,随着Ce替代量的增加,合金的晶胞体积逐渐减小,轴比c/a逐渐增大;随替代量的增加合金的放电容量逐渐降低,其高倍率放电性能先提高后降低,x = 0.25时合金的倍率放电性能最好;而合金的循环寿命随Ce替代量的增加而逐渐提高;随替代量的增加合金的最大吸氢量逐渐减小,但其放氢平台压力却逐渐提高。

La1-xCex(NiCoMnAl)5.05(x = 0, 0.25, 0.50, 0.75) series alloy is prepared by induction melting method; the PCT gaseous hydrogen absorption and desorption test is also carried out. The results show, with the increase of Ce substitution amount, the unit cell volume of alloy decreases gradually, and the axial ratio c/a increases gradually; with the increase of substitution amount, the discharge capacity of alloy decreases gradually, and its high rate discharge performance firstly increases and then decreases, and the discharge performance of alloy at x = 0.25 is the best; the cycle life of alloy is gradually improved with the increase of Ce substitution; with the increase of substitution amount, the maximum hydrogen absorption of alloy decreases gradually, but hydrogen desorption plateau pressure increases gradually.
