We report a new class of single-ion electrolyte including pendant lithium perfluoroethyl sulfonates. Embodiments may be based on, for example, aromatic poly(arylene ether)s, polyphenylenes, or polyarylene sulfides. The microporous polymer film saturated with organic carbonates exhibits a nearly unity t.sub.Li+, state-of-the-art conductivities (e.g. >10.sup.−3 S cm.sup.−1 at room temperature) over a wide range of temperatures, high electrochemical stability, and outstanding mechanical properties, which enables the membrane to function as both ion conducting medium and separator in the batteries.

The present invention exploits reactive organophosphorus compounds containing unsaturated vinyl groups, which can be used in a flexible and highly controlled manner to prepare various macromolecular derivatives either via radical reactions or via Michael addition with suitable nucleophiles. Based on the fact that secondary amine groups on the one hand and vinyl groups on the other hand can work as mutual linking sites, an arsenal of novel and useful addition products can be built up. By selecting the number of secondary amine sites and vinyl sites of the participating reaction partners, very different addition products can be formed. In particular, one can form either linear chain type macromolecules (i.e. linear oligomers or polymers) or highly crosslinked network polymers.
