| Abstract: | La2Mg16Ni hydrogen storage allo was prepared by melting with covering flux,and its hydriding-dehydriding performance and phase structure transformation during the hydriding-dehydriding process were researched.It was shown that the partial substitution of nickel for magnesium in La2Mg17 alloy caused the improvement of hydriding-dehydriding kinetics performance of the hydrogen storage alloy.The so-prepared alloy possessed good hydriding-dehydriding properties at a temperature of more than 553K with a hydrogen storage capacity up to 4.16 wt%. |
