摘　　要：研究了形变对ＭＨ电极结构与电化学性能的影响，研究表明，形变量增加，轧制力增加，ＭＨ电极表面贮氢材料比例增加，Ｎｉ网比例减少，轧制道次增加，每道次形变量减少，则ＭＨ电极容量降低。The effect of deformation on the structure and electrochemical properties of MH electrode was studied . It had been shown from the results that the more the degree of the cold work,the greater the rolling force and the more the ratio of the hydrogen storage materials on the surface of MHelectrode, and that the more the rolling times and the less the degree of cold work per rolling, the less the electrochemical capacity , the faster the decreasing of the capacity while cycle testing.
