本文利用阴极极化电沉积法和化学浸渍法分别制备了含Cd量在5％以内的薄膜式和烧结式氢氧化镍电极，借助循环伏安和恒电位阶跃等技术考察了薄膜电极在氧化还原过程中质子的扩散系数，结果为10(-10)～10(-9)cm2／s;并研究了烧结式电极恒电流放电性能，其放电中值电位较好，在与Co同时添加的情况下，该值决定于两者的含量比．
In this paper, thin-film and sintered nickel hydroxide electrodes containing 5% Cd were prepared respectively by cathodic polarization electrodeposition and chemical immersion. The effects of oxidation The diffusion coefficient of proton in the process of reduction was 10 (-10) -10 (-9) cm2 / s. The galvanostatic discharge performance of the sintered electrode was studied. The discharge median potential was good. In the case, the value depends on the content ratio of the two.
