| 摘 要： | 采用电弧炉熔炼方法制备La0.6CexNd0.4-xNi3.0Co0.2Al0.3(x=0～0.4)系列合金,并对合金的储氢性能和电化学性能进行测试。测试结果表明,合金在Ce=0时具有最高的电化学容量(284.2mAh/g)和储氢量(0.93wt%)。Ce的添加会降低合金放电容量,但是能够改善合金的循环稳定性能。

| Abstract: | La0.6CexNd0.4-xNi3.0Co0.2Al0.3 (x=0~0.4)hydrogen storage alloys were prepared by induction melting, the hydrogen storage and electrochemical properties of the alloys were measured and analyzed in detail. The results show that La0.6Nd0.4Ni3.0Co0.2Al0.3 alloy has better hydrogen storage capacity and higher electrochemical properties. The addition of Ce can decrease the discharge capacity but enhance the cycling stabilities. |
