Zr_(1-x)Ti_x(NiCoMnV)_(2.1)贮氢合金负极片的制备与性能

Preparation and Characteristics of Zr(1-x)Tix(NiCoMnV)2.1 Hydride Alloy Electrodes

通过添加镍粉或碳黑制备了Zr(1-x)Tix(NiCoMnV)2.1负极片. 对其进行了还原剂热充电预处理；测试了各种负极片的放电容量. 结果表明：以镍粉为导电剂的Zr(1-x)Tix (NiCoMnV)2.1负极片性能明显高于以碳黑为导电剂的负极片；而以镍粉为导电剂、添加银粉的负极片经过还原剂热充电预处理性能较佳，其初始容量能达到215 mA·h/g，平台Ｋ值大于90%.

Zr(1-x)Tix(NiCoMnV)2.1 hydrogen-storing alloy electrodes are prepared by adding nickel or carbon black conductor. Some electrodes are pre-treated by being charged in hot reducing agent. The discharge capacity is tested for each electrode. The results show that the properties of Zr(1-x)Tix(NiCoMnV)2.1 hydrogen-storing alloy electrode with nickel conductor are apparently better than those of electrode with carbon black. The performance of the electrode with nickel conductor and Ag additive with charging treatment in hot reducing agent is the best, the initial discharge capacity of this electrode can be up to 215 mA·h/g, and the plateau value about to 90%.
