A maximum hydrogen amount of 9.1 wt % was obtained at 300 °C from the 1Mg(NH2)2−2LiH−0.67LiBH4 system. Various analyses and thermodynamic calculations revealed that the MgH2 and LiNH2 can be readily converted to Mg(NH2)2 and LiH at 120 °C in the presence of LiBH4. A comparison between the sample 1Mg(NH2)2−2LiH−1LiBH4 and the ternary mixture 1MgH2−2LiNH2−1LiBH4 indicated that both samples behave very similarly in hydrogen desorption, thermal effects, and chemical changes during dehydrogenation.
