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.
