Abstract
The dehydrogenation behavior of 6LiBH4 + CaH2 + 0.2NbF5 composite has been investigated. It is demonstrated that the addition of NbF5 is effective in lowering the dehydrogenation temperature of this composite. The composite starts dehydrogenation before the melting of LiBH4 and releases 9.1 wt.% hydrogen up to 400 °C. The equilibrium dehydrogenation temperature under 1 bar of hydrogen is estimated to be 309 °C with a reaction enthalpy change of 56.5 kJ mol−1 H2, which is consistent with thermodynamic calculation.
