Enhanced room temperature ionic conductivity of the LiBH4·1/2NH3–Al2O3 composite†
Abstract
A novel LiBH4·1/2NH3–Al2O3 composite was demonstrated, in which amorphous LiBH4·1/2NH3 was in situ formed on the surface of Al2O3 owing to the strong interfacial interaction via B–O bonds. The ionic conductivity of LiBH4·1/2NH3 is improved by one order of magnitude to 10−3 S cm−1 and the electrochemical window up to 3.6 V.
