Abstract

The ionic conductivities, NMR T₁ and the D's [i.e., solvent (¹H), anion (¹⁹F), and lithium ion (⁷Li)] were measured as functions of temperature for the 14 electrolytes composed of seven solvents. The relationships between the correlation times of the CH₂CH₂O segmental and the lithium hopping motions, the individual diffusion coefficients, ionic conductivity, ion dissociation, and the interactions between the solvent and the lithium ion were detailed in terms of the dependence on the n. Solvent aggregation effects in the electrolytes were also highlighted.
