Improved dehydrogenation performance of LiBH4/MgH2 composite with Pd nanoparticles addition

Effects of NbF5 addition on the de/rehydrogenation properties of 2LiBH4/MgH2 hydrogen storage system

“…As the temperature further increases to 420 C, the borohydride completely converts to MgB 2 and LiH, as well as a trace MgF 2 which is favorable to improving the hydrogen exchange kinetics of LiBH 4 [28]. It is remarkable to note that, the thermodynamics stability of 2LiBH 4 /MgH 2 system could be reduced because of the formation of MgB 2 , and the rehydrogenating reaction between MgB 2 and LiH was also more favorable than B with LiH [29]. Furthermore, it was also reported that a small number of LiF/MgB 2 products could facilitate the reversible rehydrogenation process effectively [30].…”

Improvement of hydrogen-storage properties of MgH2 by addition of Li3N, LiBH4, Fe and/or Ti

“…Weng et al [14] reported the improvement in the dehydrogenation performance of LiBH 4 /MgH 2 composite by Pd nanoparticles addition. Nakagawa et al [15] investigated the TiCl 3 -doped MgH 2 -LiBH 4 system, and reported the formation of MgB 2 above 400 8C.…”

Thermodynamics of the dehydrogenation of the LiBH4–YH3 composite: Experimental and theoretical studies

“…The formation of a thermodynamically stable metal boride is expected to reduce the overall enthalpy change of the dehydrogenation reaction and subsequently the dehydrogenation temperature. A variety of combinations of LiBH 4 and metal hydrides, such as LiBH 4 -MgH 2 [7][8][9], LiBH 4 -CaH 2 [10], LiBH 4 -CeH 2 [11], LiBH 4 -YH 3 [12], LiBH 4 -LiAH 4 [13] and LiBH 4 -Li 3 AlH 6 [14], have been evaluated to improve the hydrogen sorption properties of LiBH 4 . In many cases, a decrease in the dehydrogenation tem- * Corresponding author.…”
