Effects of Mn content on the hydrogen-induced amorphization of LaNi3-xMnx(x=0.0,0.1,0.3 and 0.5)hydrogen storage alloys were studied systematically.All the alloys were prepared using a rapid quenching and annealing method.As the charging time increased,the hydrogen-induced amorphization occurred gradually in all the compounds for the first cycle.During the discharge process,discharge potential plateau was not observed in LaNi3.As Mn content increased,however,structural changes were inhibited partly,and a plateau evolved gradually in the discharge curves.
