Lithium organic salts with extra functionalities
Résumé
Lithium perfluorosulfonate salts have been tailored either to provide solvating and/or plasticizing effect, or polar function. Adding these extra functionalities to the organic anion result in a good combination of ionic conductivity and cationic transference number. The high cationic conductivity obtained for polymer electrolytes at the concentration O/Li=30 must be emphasized.
