Abstract

The effect of LiBH₄ on the hydrogen sorption performance of magnesium was investigated. It was found that the hydrogen storage properties of LiBH₄/Mg mixtures exhibit a dramatic improvement as compared to plain magnesium powder. For example, at 250°C, a LiBH₄/Mg (mass ratio 1:4) composite can absorb 6.7 wt% hydrogen in 60 min, while only less than 1 wt% hydrogen was absorbed by pure magnesium in the same period under similar conditions. The hydrogen desorption properties of the composite at 350°C were also improved significantly as compared to the plain magnesium powder. Furthermore, highly activated magnesium hydride was synthesized directly by ball milling LiBH₄/Mg mixtures under high hydrogen pressure. The synthesized magnesium hydride exhibits superior kinetics, absorbing 5.78 wt% hydrogen at the relatively low temperature of 200°C within 100 min. © 2007 American Chemical Society.
