| Abstract: | In order to compare the characteristics of electrochemistry and dynamics tor AB5 and AB3.5 hydrogen storing alloys, the AB5 MlNi3.68 Mn0. 32 Co0. 73 Al0.27 and AB3.5 Ml0. 80 Mg0. 20 （NiMnAlCu） 3.6, La0.66 Mg0. 4 Ni3.5 alloys are as the object of study. The phase structures of alloys are analyzed with XRD, the characteristics of electrochemistry and dynamics for alloys are tested with the electrochemical method. The results show that the MlNi3.68Mn0.32 Co0.73A10.27 alloy is composed by single - phase LaNi5 while Ml0. 80 Mgo. 20 （ NiMnAlCu ） 3.6 and La0. 6 Mg0, 4 Ni3.5 all contain LaNi5 and La2 Ni7 phases. The discharge capacity, retention rate of charge and characteristics of dynamics for AB3.5 alloy are higher than those of AB5 alloy. |
