【摘要】 <正> 镍/氢化物（Ni/MH）电池以其洁净、安全、高容量、大功率、长寿命而受到人们的极大关注。贮氢电极材料的研究是开发Ni/MH电池的中心,已有较多报道。Boonstra等研究了氧化、粉末的处理等对LaNi₅电极性能的影响。本文探讨电解液浓度对MLNi_3.5MnCO_0.4Al_0.1（ML代表富镧混合稀土）电极放电性能的影响,并对其循环伏安性能进行了研究。 贮氢合金是在氩气保护下,将计量比的各组成元素ML、Ni、Mn、Co、Al混合物在高频感应更多还原

【Abstract】 The discharge characteristics of MLNi_3.5MnCo_0.4Al_0.1 （ML=mixed rare earths rich in lanthanum） hydrogen storage electrode were studied in the KOH solution of different concentration. The discharge capacity, fast discharge ability, selfdischarge rate of MH electrode were found to be improved by increasing the electrolyte concentration. The linear relationship between I_p and v^1/2 values obtained from cyclic voltammetry curves indicated that the reactions at the electrode were controlled by diffusion process.更多还原
