优化合金组成,设计六种锆基AB2型贮氢合金材料.XRD分析表明,当0≤x≤0.5时,Zr1-xTix(NiCoMnV)2 1贮氢合金的主相都是Laves C15,但随Ti含量的增加,Laves C14相含量增多;当用V-Fe(85.6%)合金代替Zro 6 Ti0.4(NiCoMn-VFeCr)1.7中的V时,贮氢合金中Laves C14相的含量几乎可与Laves C15相当.电化学测试表明:Zr0.9Ti0.1(NiCoMnV)2.1贮氢电极的放电容量可达340mAh/g左右,但是随着Ti含量的逐渐增加,合金电极的放电容量降低很快.以适量的(V-Fe)合金取代Zr0.6Ti0.4(NiCoMnVFeCr)17合金中的V和Fe,发现合金电极的第一次放电容量就能达到200mAh/g左右,并且其容量稍高于含纯V的合金电极,容量可达315mAh/g左右.
