COMPARATIVE ION-TRANSPORT IN SEVERAL POLYMER ELECTROLYTES

A comparative transport number study on a wide variety of lithium salt s was performed, confirming the prevalence of an anionic transport in most of the usual salts dissolved in a polyether network. A cationic t ransport close to 0.5 was determined for several perfluorosulfonate ba sed polymer electrolytes. The method used confirmed a transport number close to unity for a perfluorosulfonate-based ionomer. (C) 1997 Elsev ier Science S.A.
