1H, 7Li, and 19F nuclear magnetic resonance and ionic conductivity studies for liquid electrolytes composed of glymes and polyetheneglycol dimethyl ethers of CH3O(CH2CH2O)nCH3 (n = 3 - 50) doped with LiN(SO2CF3)2

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.
