Lithium-beryllium metal hydrides, which are structurally related to their parent compound, BeH[subscript 2], offer the highest hydrogen storage capacity by weight among the metal hydrides (15.93 wt. % of hydrogen for LiBeH[subscript 3]). Challenging synthesis protocols have precluded conclusive determination of their crystallographic structure to date, but here we analyze directly the hydrogen hopping mechanisms in BeH[subscript 2] and LiBeH[subscript 3] using quasielastic neutron scattering, which is especially sensitive to single-particle dynamics of hydrogen.
