摘　　要：研究了热处理时间对储氢合金LaNi3.6 Co0 .7Mn0 .4 Al0 .3的相结构、活化性能、高倍率放电性能及循环稳定性的影响。经过不同热处理时间处理的合金 ,a轴变长 ,c轴缩短 ,晶胞体积增大。热处理时间为 3h时 。The effects of heat treatment time on phase structure, activities, high rate discharge property and cycle life of a hydrogen storage alloy--LaNi 3.6Co 0.7Mn 0.4Al 0.3 are studied. After its heat treatment the alloy has an increased A-axis, a reduced C-axis and an increased space unit. At a heat treatment time of 3 h, the alloy electrode exhibites its better high rate discharge properties and cycle life.
