【Abstract】 A variety of nickel electrodes containing Zn were prepared by doping and by coprecipitation. The effects of Zn addition methods on the electric properties of the nickel electrode were studied. The results show that addition of Zn either by doping or by coprecipitation can improve the electric properties of nickel electrode, the charge efficiency and the transportation ability of H +, whereas the later method appeared better. The cyclic voltammetry revealed an improvement of the reversibility of nickel electrode . The optimum Zn content was 1 0%~3 0%.更多还原
