发展了两种贮氢合金表面处理新方法．光电子能谱和循环伏安实验表明，经过处理后得到了富镍表面层，可提高电极的反应性能．采用光电化学方法对不同处理的电极表面由动电位氧化形成的氧化膜进行了表征，分别观察到与表面膜吸附氢氧化和氧化还原反应有关的阳极光电流和阴极光电流，同时依照电极在循环过程中的光电流变化区分了两种处理方法所得到的表面层抗氧化性能之差异．通过粉末单电极初期充放电实验，证实了电极经方法１处理以后其放电性能得到提高．
Two new methods have been developed for the surface treatment of hydrogen storage alloys. Photoelectron spectroscopy and cyclic voltammetry experiments show that after treatment, nickel-rich surface layer can be obtained, which can improve the reactivity of the electrode. The photoelectrochemical method was used to characterize the oxide films formed by the Zeta potential oxidation on the surface of the electrodes. The anode photocathode and cathodic photocurrent related to the adsorption of hydrogen and redox reactions on the surface were observed respectively. Meanwhile, The change of photocurrent during the process distinguishes the difference of antioxidant properties of the surface layer obtained by the two treatment methods. The initial charging and discharging experiments of powder single electrode confirmed that the discharge performance of the electrode was improved after the method 1 was treated.
