研究了贮氢电极合金Zr1-xTixM0.7V0.2Co0.1Ni1.2的相结构和电化学性能.结果表明,随着掺Ti量的增加,该合金主相中C15型Laves相含量逐渐减少而C14型Laves相含量逐渐增加,同时非Laves相Zr7M10和TiNi相全部消失,说明元素Ti掺杂量的增加抑制了第二相的产生.当含Ti量x=0.2时,该合金具有最大放电容量Cmax为354mAh/g,在放电电流为300mAg/g条件下,高倍率放电性能比母体合金提高了15%.而对于合金Zr0.75Ti0.2La0.05Mn0.7V0.2Co0.1Ni1.2,其活化性能被大大提高,只需4次就能达到最大放电容量372mAh/g,而且经过30次循环仍能保持最大放电容量的93%.
