摘　　要：研究了不同种类缓蚀剂及不同处理方式对非晶态镁基储氢电极充放电循环稳定性的影响。实验结果表明,缓蚀剂可以改变镁基储氢电极表面与电解液之间的界面性质,在不显著降低电极最大初始容量的同时,改善了电极的循环稳定性。The effect of the different kinds of anti-corrosion agent and different treatment modes on the charging/ discharging cych stability of amorphous,Mg-based hydrogen storage electrbde was investigated. The results showed that anti-corrosion agent could change the characteristics of the interface between the Mg-based hydrogen storage electrode surface and the electrolyte, and then improve the cycling stability of the electrode while not remarkably decrease the initial capacity of the electrode.
