Determination of Mass Transfer Parameters and Ionic Association of LiPF6: Organic Carbonates Solutions

We report herein on the determination of several mass transport properties (diffusion coefficients for cations, anions, and neutral ionic aggregates; cation transference number) and degree of salt association in electrolyte solutions of practical interest (LiPF6 solutions in binary organic carbonate mixtures), through an analysis of pulsed field gradient NMR and specific conductivity data. Results were obtained as a function of LiPF6 salt …
