There is great interest in destabilised multicomponent hydrogen storage materials as this allows the reduction of the temperature of dehydrogenation while maintaining a reasonably high hydrogen capacity [1]. One example is the use of MgH2 to destabilise LiBH4 with different molar ratios. The current proposal is a direct continuation of our previous DINS experiment. The aim is to draw an accurate kinetic energy map of each element following the classic destabilization reaction of LiBH4 by MgH2. Available INS data revealed that the kinetic energies found at each stage of the reaction were different from those obtained from the raw components suggesting a change in each atomic environment. Ex-situ samples will be investigated.
