Abstract
The nanoconfinement of LiBH4 into mesoporous Al2O3 as a fast lithium-ion conductor is presented, and its high-temperature phase is retained at near-room temperature. It exhibits an excellent electrochemical stability and Li+ conductivity of 3.2 × 10-4 S cm-1 at 75 °C, which represents an increase of nearly three orders of magnitude compared to the pristine one.
