| 摘 要： | 在稀土镍合金贮氢电极(MH)的研究中,曾报道电解液浓度对MLNia_(3.5)MnCo_(0.4)Al_(0.1)(ML代表富镧混合稀土)电极放电性能的影响。本文报道Al含量对MLNi_(4-x)MnAl_x电极性能的影响,并用循环伏安法对电极反应机理进行了探讨。实验方法同前报。 结果与讨论 MLNi_(4-x)MnAl_x电极性能测试 用100mA/S恒电流将MLNi_(4-x)MnAl_x电极充电至300mAh/g,停充10分钟,再用100mA/g恒电流放电至—0.60V(vs Hg/HgO),得如图1的放电曲线。可见随

| Abstract: | The electrochemical performances of MLNi_(4-x)MnAl_x hydrogen storage alloys with different Al content have been studied. The results showed that the discharge capacity,fast discharge ability,overpotentials and cycle life of the MLNi_(4-x)MnAl_x electrodes were affected by Al contents. The cyclic voltarnmetry of MH electrodes exhibited a good linear relationship between I_p and v~(1/2),suggesting MH electrode reaction being controlled by diffusion process. |
