Abstract

Rehydrogenation behavior of the discharged MgH₂-LiALH₄ composites was investigated by using thermal gravimetric analysis (TGA) and in situ synchrotron X-ray diffraction (XRD) technique. For 4MgH₂-LiALH₄ composite, the experimental results showed that at least 3 wt% of hydrogen could be recharged at 170 psi H2/400°C to form MgH₂ after its first dehydrogenation reaction. The XRD results indicated that not only Mg but also Mg17Al12 could be rehydrogenated in the hydrogen atmosphere investigated although LiALH₄ was found irreversible.
