摘　　要：涂膏式镉负极因为制造工艺简单 ,成本低而得到广泛应用 ,然而其大电流充放电能力和循环使用寿命比烧结式镉负极差。通过在镉负极表面镀覆一层金属镍 ,提高了涂膏式镉负极的大电流充放电能力 ,电极容量也得到了提高。The pasted Cd anodes were used widely since its manufacture processes were simpl er than those of the sintered Cd anode, thus their cost was lower. However, comp ared with the sintered Cd anode, the pasted Cd anode perform ance, such as the large discharge-charge efficiency, the cycle life, was n ot satisfacto ry. The electrode performance was enhanced by eletro-depositing a film of nick el metal on the surface of the Cd anode. The large discharge-charge effici ency and the electrode capacity were improved.
