| 摘 要： | 利用排水集气法、交流阻抗测试技术、充放电曲线研究了AB5贮氢合金电极的充放电过程。结果表明:在实验选择的充放制度下,充电倍率对贮氢电极的充电电位、充电效率及放电倍率对放电性能有明显的影响;在放电过程中,贮氢电极表面电化学反应阻抗随放电深度增加而减小,当放电深度大于80%时电化学反应阻抗又增大。

| Abstract: | The charge/discharge process of hydrogen storage electrodes was investigated by H2 collection process with displacement,electrochemical impedance spectroscopy(EIS) and by charge/discharge curves.The results showed that charge rate has obvious influence on charge electrode potentials and charge efficiency and discharge rate has obvious effect on discharge performance;electrochemical reaction impedance of the MH electrode decreased with the increase of depth of discharge,and increased when the DOD was above 80% in discharge process. |

| Keywords: | MH electrode PCT curve charge efficiency AC impedance |
