Greater than the sum of its parts : Hydrogen storage in complex hydrides is accelerated by using the ternary composite 2 LiNH 2 /LiBH 4 /MgH 2 , which exhibits a “self‐catalyzing” reaction pathway that results in faster H 2 desorption, lower desorption temperatures, and suppression of NH 3 release in comparison to the constituent binary composites (see diagram). The enhanced properties arise from the incorporation of an ionic liquid phase (Li 4 BH 3 H 10 ) and from ancillary‐reaction seeding of a reversible H 2 storage reaction.
