Abstract
Abstract A macromolecular material displaying ionic conduction, comprised of a salt in solution in an organometallic polymer. The organometallic polymer comprises an organic polymer in which a metal atom is directly connected by the intermediacy of an oxygen atom to at least two of the organic polymer chains. The material is applied in the production of electrochemical generators.
