Ionic conductivity of lithium conducting SiO2gels at room temperature

Marek Wasiucionek , M. W. Breiter

Abstract

Fresh silica gels have been used as hosts for liquid organic lithium electrolytes. The residual liquid inside the fresh gels was exchanged by the solutions of selected lithium salts (lithium hexafluorophosphate, lithium tetrafluoroborate) in organic solvents: propylene carbonate (PC), dimethyl sulfoxide (DMSO), dimethyl formamide (DMF), 1,2-diethoxyethane (DEE) and dimethyl carbonate (DMC). The immersion of the gels in solutions based on DEE, DMF and DMC leads to the fast deterioration of the gels. The gels immersed in the solutions based on PC and DMSO exhibit stable conductivities in the range of 10-3S cm-1 at room temperature. That conductivity is close to the conductivity of the corresponding lithium salt solutions.
