Conductivity-temperature behavior of organic electrolytes

Abstract

Conductivity vs. temperature data for Li salt solutions in a number of organic carbonate solvents correlate well with the Vogel-Tammann-Fulcher equation over a wide Li salt concentration range. The results are consistent with a solvent-assisted ionic conductivity mechanism; we attribute this to the strong interaction between organic Solvent molecules and Li ions. It is demonstrated that solvent-assisted ionic transport may be a general phenomenon in aprotic organic electrolytes containing Li salts.
