Comparative ion transport in several polymer electrolytes

A comparative transport number study on a wide variety of lithium salts was performed, confirming the prevalence of an anionic transport in most of the usual salts dissolved in a polyether network. A cationic transport close to 0.5 was determined for several perfluorosulfonate-based polymer electrolytes. The method used confirmed a transport number close to unity for a perfluorosulfonate-based ionomer.
