Thermodynamic and kinetic destabilization in LiBH4/Mg2NiH4: promise for borohydride-based hydrogen storage

Thermodynamic and kinetic destabilization in LiBH4/Mg2NiH4: promise for borohydride-based hydrogen storage

The reversible LiBH(4)/Mg(2)NiH(4) combined hydride system for hydrogen storage displays a concerted dehydrogenation reaction beginning at 250 degrees C with significantly low enthalpy (DeltaH = 15.4 +/- 2 kJ mol(-1) H(2)) and entropy (DeltaS = 62.2 +/- 3 J K(-1) mol(-1) H(2)).
