Determination of Mass Transfer Properties and Ionic Association in LiPF6 - Organic Carbonates Solutions from PFG-NMR and Specific Conductivity Data

We derive herein several mass transport properties (diffusion coefficients for cations, anions, and neutral ionic aggregates; cation transference number; salt association constant) of LiPF6 solutions in binary mixtures of ethylene carbonate (EC) and dimethyl carbonate (DMC) or ethyl methyl carbonate (EMC) through an analysis of PFG-NMR and specific conductivity data. Results were obtained as a function of salt concentration for EC:DMC 1:1 v/v, …
