Low-temperature ionic conductivity of relevant solutions and of SiO2 gels before and after exchanges in propylene carbonate solutions

Marek Wasiucionek , M.W Breiter

Abstract

The ionic conductivities of a series of SiO2 gels both as-received and exchanged in propylene carbonate solutions (PC, LiPF6+PC and LiBF4+PC) were measured in the temperature range 120–300 K. Relevant solutions were also studied. The temperature dependences of the conductivity of fresh sols and as-received gels did not follow the Arrhenius equation. They were fitted using the Vogel–Tammann–Fulcher formula. After the solvent exchanges, the temperature dependence of the conductivity of the gels resembled that of the exchange solutions.
