Abstract

The present invention relates to novel macromolecular materials constituted by a salt in solution in a copolymer of ethylene oxide and of a second monomeric unit the structure of which preserves on the chain a polyether structure. The application of the invention is particularly useful in the realization of composite electrodes and electrolyte of primary or secondary electrochemical generators, thus necessitating the excellent conductivities of these materials.
