摘要
研究了负极材料为Mm0.8La0.2Ni4.0(MnCoAl)1.0贮氢合金的MH-Ni电池的充放电性能,在0.2A电流下的充电电压和放电电压分别为1.4V和1.2V,充电效率为89.1%。电池贮存30天自放电率为22.6%,其原因为电极中氢的解吸和贮氢合金的氧化。
The charge--discharge characteristics of MH-Ni battery using Mm0.5La0.2Ni40 (MnCoAl)10 hydrogen storage alloy anode were studied. The results have shown that the charge and discharge voltage of the battery is 1.4V and 1.2V at 0.2A curren4 respectively. The charge efficiency is 89.1%. Since the hydrogen desorption and hydrogen storage alloy oxidation in the electrode, the self-discharge ratio of the battery is 22.6% in 30 days storage.
