摘　　要：通过添加不同的导电剂和添加剂，制备了Zr1(xTix-NiCoMnV)2.1贮氢合金负极片，测试了不同负极片的放电容量. 结果表明：以镍粉为导电剂的Zr1(xTix-NiCoMnV)2.1负极片性能明显高于以碳黑为导电剂的负极片, 添加银粉的负极片初始容量能达到215 mA(h/g，平台K值大于90%.Zr1(xTix(NiCoMnV)2.1 hydrogen alloy electrodes are prepared by adding different conductors, binders and additives. The discharging capacity is tested for each electrode. The results show that the properties of the Zr1(xTix(NiCoMnV)2.1 hydrogen alloy electrode with nickel conductor are apparently better than that of the electrode with carbon black. The electrode with nickel conductor and Ag additive is the best, the first time discharging capacity of this electrode can be up to 215 mA(h/g, and plateau value is about 90%.
