Short-range order in LiBH4:3LiNH2 potential key to understand high hydrogen mobility below the melting point

The compound LiBH4:3LiNH2 is thought to be the determining factor in high hydrogen ab- and desorption rates of a complex hydride hydrogen storage candidate. Recent QENS measurements showed that the hydrogen mobility increases already below the material's melting point to liquid-like values. This measurement aims to elucidate the structural mechanism behind this phenomenon.
