Abstract: 
Mg-25 wt% Mg2Ni composite was prepared by sintered method, hydrided at 613 K and then ball-milled with 1.5 wt% pdCl2 additive for 51 h. The effects of PdCl2 on the hydriding and dehydriding behavior of Mg-25 wt% Mg2Ni composite were investigated. The absorption and desorption rate of the composite with PdCl2 is fast and the hydrogen storage capacity is more than that of the composite without PdCl2. The maximum hydrogen storage capacity reached 3.48 wt% at 373 K, and 5.05 wt% H at 453 K, respectively. The improvement of sorption and desorption kinetics is attributed to the catalytic effect of PdCl2, and the grain refining and lattice strain introduced by ball milling.
