Reversible hydrogen storage in metal-doped Mg–LiBH4 composites
Composite powders of Mg50Ni and Mg15Fe with LiBH4 have been produced by short-time milling under an argon atmosphere. These composites show enhanced reversible hydrogen capacities of 7 wt.% (Ni) and 5.5 wt.% (Fe) at 573 K in just 300 s. The presence of LiBH4 does not modify the thermodynamic of the...

| Summary: | Composite powders of Mg50Ni and Mg15Fe with LiBH4 have been produced by short-time milling under an argon atmosphere. These composites show enhanced reversible hydrogen capacities of 7 wt.% (Ni) and 5.5 wt.% (Fe) at 573 K in just 300 s. The presence of LiBH4 does not modify the thermodynamic of the composites, but does account for their improved kinetic behavior. As evidence of a new kind of Mg-B interaction, MgNi3B2 is clearly identified after successive hydrogen sorption cycles below 623 K. |
