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.
