Abstract
两步电弧熔炼法制备Ti 0.10 Zr 0.15 V 0.35 Cr 0.10 Ni 0.30 + 5wt% La 0.85 Mg 0.25 Ni 4.5 Co 0.35 Al 0.15 复合储氢合金, X射线衍射(XRD)和扫描电镜?能谱(SEM-EDS)显示: 复合储氢合金的主相是体心立方结构的钒基固溶体相和六方结构的C14 Laves相, 复合过程中生成了第二相. 电化学研究表明: 复合过程中存在明显的协同效应; 在303 K时, 复合合金电极的实际最大放电容量为361.8 mAh/g; 在233 K时, 复合合金电极的低温放电能力(LTD)是母体合金电极的4.05倍. 与母体合金电极相比, 复合合金电极的高倍率放电性能(HRD)提高了26.87%, 电荷转移电阻(Rct)减小了37.25 mΩ, 同时交换电流密度(I0)增大了115.45 mA/g, 合金体内氢的扩散系数(D)增大了6.13×10 -10 cm 2 /s.
