Preparation and Characterization of Mesoporous Silica and Lithium-Ion-Conductive Halocomplex Salt Composite

Abstract

Composites of mesoporous SiO2and LiAlCl4were synthesized, and the change in ionic conductivity due to the formation of the composites was investigated. The electrical conductivity of the composite with the SiO2: LiAlCl4of 2 : 3 was the highest with a value of 2 x 10-6S/cm at room temperature. A higher order of conductivity was observed for the composite compared to the non-composite LiAlCl4. In addition, it was found that the conductivity of the composites depends on the pore size of the mesoporous SiO2.
