Abstract

Solvated lithium closo-dodecaborate, Li₂B₁₂H₁₂ with tetrahydrofuran and acetonitrile, show unexpected melting below 150 °C. This feature has been explored to melt-infiltrate Li₂B₁₂H₁₂ in a nanoporous SiO₂ scaffold. The ionic conductivity of Li₂B₁₂H₁₂·xACN reaches 0.08 mS cm⁻¹ in the liquid state at 150 °C making them suitable as battery electrolytes.
