An aluminum doped α Ni（OH） 2 was prepared by coprecipitation method and was used as nickel electrode for secondary batteries. Its crystal form was determincd by XRD and electrochemical performance was studied by cyclic voltammetry and galvanostatic charge/discharge method. The experimental results indicated that the capacity on the charge/discharge and the discharged potential are higher than the conventional β Ni（OH） 2 electrode.\; 镍电极 充放电容量 充放电性能 nickel elelctrode capacity on charge/discharge performance on charge/discharge O646.541 1999-06-01 2021-04-01 6
