This work presents detailed studies of the crystal structures and thermal properties of rare-earth (RE) borohydrides. The compounds show a big structural variety with anion substation, polymorphism, difference in coordination numbers and multiple oxidation states. The thermal decomposition of the mixtures has been studied by in situ synchrotron radiation powder X-ray diffraction. Composites with RE-borohydrides and LiBH4/LiH could be cycled at relatively mild conditions.
