A nanosheet-like lithium borohydride hydrate (LiBH 4 ·H 2 O) measuring 20-30 nm in thickness is successfully synthesized for the first time by a facile, scalable freeze-drying strategy. The prepared LiBH 4 ·H 2 O nanosheets start releasing hydrogen below 50 °C and release an amount up to approximately 10 wt % at 70 °C because of the strong affinity of H + in the H 2 O ligand and H - in the BH 4 group. The reported dehydrogenation properties here are superior to those of all known complex hydrides, indicating applicability as an advanced chemical hydrogen storage medium.
