Abstract
A dehydriding property of xLiBH4 + (1 - x)Mg2FeH 6 (x = 0.10.83) was investigated. The dehydriding reactions of pure LiBH4 and Mg2FeH6 start at approximately 650 and 450 K, and 12.5 and 4.3 mass% hydrogen are released, respectively. The property drastically changes by combining LiBH4 and Mg 2FeH6. Within the composition range 0.1 ≤ x ≤ 0.5, LiBH4 and Mg2FeH6 simultaneously release hydrogen. The reaction temperatures and quantities of released hydrogen alter with x. The lattice parameter of the Mg2FeH6 phase measured by in-situ highresolution synchrotron diffraction measurements suggest the possibility of forming LixMg2-2x(BH4) x(FeH6)1-x with both double-cation and double-anion.
