Hydrogen back pressure remarkably promotes the formation of metal boride during, the dehydrogenation of 4LiBH(4) + YH3, 6LiBH(4) + CeH2 and 6LiBH(4) + CaH2 composites, which seems to be a general phenomenon in LiBH4-based reactive, hydride composites that enables mutual destabilization,between LiBH4 and metal,hydride. The formation of metal boride plays a crucial role in the reversible hydrogen storage properties of these composites. The dependence of the dehydrogenation behavior on hydrogen back pressure might be associated with the microstructural evolution of the dehydrogenation products formed by a solid liquid reaction.
