Abstract Scope Nanoconfined metal hydrides have many attractive features for integration into solid-state batteries and hydrogen fuel cells, in particular for vehicular applications, where weight and volume are critical. I will present recent results that demonstrate that nanoconfinement of metal hydrides can be used to overcome the unfavorable thermodynamics of direct aluminum hydrogenation by stabilizing AlH3 and LiAlH4 within nanoporous carbon and Covalent-Triazine Framework nanoporous hosts, rendering the hydrides reversible. In the area of solid-state electrolytes, we demonstrated that nanoconfinement of Li2B12H12 and LiCB11H12 in nanoporous silica (8-12 nm pore sizes) yields dynamically disordered closo-(car)borate anions exhibiting liquid-like reorientational mobilities, with superionic cation conductivities down to room temperature. These results point out to possible uses of the nanoconfinement strategy to advance novel materials concepts in electrochemical energy storage devices and hydrogen storage.
