Lithium hydride, hydrogen storage

Another interesting lithium-based system is Li3N/Li2NH [53]. Lithium nitride can be hydrogenated to lithium imide and lithium hydride (5.4 wt% H2). The latter reaction can be used for reversible storage at 250°C. The formation of ammonia can be completely avoided by the addition of 1% TiCl3 to the system, which has the positive additional effect to improve the kinetics [54]. Very fast kinetics has been reported for a partially oxidized lithium nitride [55].

Recently, metal-doped aluminium hydrides have been proposed as further potential hydrogen storage materials [107, 123]. Among lightweight metal hydrides the lithium and sodium alanates (NaAfflU, LiAlH4) have been widely... 

Many of the studies that followed the initial report of reversible storage in the Li-N-H system followed two key reaction steps (1) the desorption step where lithium amide combines with lithium hydride to release hydrogen and...
