A prospect for LiBH4 as on-board hydrogen storage

Abstract

In contrast to the traditional metal hydrides, in which hydrogen storage involves the reversible hydrogen entering/exiting,of the host hydride lattice, LiBH4 releases hydrogen via decomposition that produces segregated LiH and amorphous B phases.,This is obviously the reason why lithium borohydride applications in fuel cells so far meet only one requirement – high hydrogen storage,capacity. Nevertheless, its thermodynamics and kinetics studies are very active today and efficient ways to meet fuel cell,requirements might be done through lowering the temperature for hydrogenation/dehydrogenation and suitable catalyst.,Some improvements are expected to enable LiBH4 to be used in on-board hydrogen storage.
