AbstractIn 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.
