Cationic conductivity in poly(oxyethylene oxide) networks

New monomer salts with a perfluorosulfonate group were synthesized. These new salts, bearing one or two double bonds, lead to cross-linked solvating ionomers. Preliminary ionic conductivities and thermal characterizations are reported for single-cation conductors polymer electrolytes. The conductivity values of these single-cation conductors are markedly higher than those reported in the literature; the conductivity loss, with respect to the free-salt complexes, corresponds approximately to the expected anionic conductivity. The aim of this communication is twofold: (i) description of the synthesis of new lithium salts, and (ii) presentation of the results obtained with poly-electrolytes having a grafted anion.
