ABSTRACT:
An ion conductor for electrochemical cells, comprising an alkali metal salt or a mixture of alkali metal salts, and mixed therewith on oligomer and/or polymer (hereinafter referred to simply as "polymers"), having at least one phosphazene base unit. The polymers are chemically stable with respect to the constituents of the ion conductor, and have an inorganic atom or an inorganic compound positioned at the phosphorous atom of at least one phosphazene base unit thereof. To form the ion conductor the alkali metal salts are heated to the melting temperature and the alkali metal salts, preferably fused to a low viscosity state, are admixed with the polymers which are dissolved in the alkali metal salt melt.
