无汞碱锰电池负极集流体的表面处理方法

分析了无汞碱锰电池负极集流体的清洗抛光、涂覆有机物、电镀和化学镀等四种表面处理方法．清洗抛光成本较低，但工艺参数不易控制；涂覆有机物简单易行，只是生产中应用不多；电镀工艺参数易于控制，但镀层光洁度不够；化学镀投资少，制备的镀层结构致密、厚度均匀．由于铟化学镀层的性能优良，无氰化学镀铟将具有更广阔的应用前景．

Surface treatment of negative current collector in mercury-free alkaline manganese dioxide batteries

Clean--polishing, organic compound painting, electroplating, and electroless plat- ing used in treatment of the surface of negative current collector are analyzed. Polishing cost is low, but its parametres are not easily controlled. Painting of organic compound is simple, but is seldom used. Electroplating parametre is easy to be controled, but coating gloss is not good. Electroless plating cost is low, and coating is compact in structure and uniform in thickness. Because of good function of indium coating, electroless plating indium without cyanogens on current collectors has broad application prospect.
