Abstract

Two ion-transport mechanisms are described for ion transport in polyether-alkali metal salt complexes: an intrahelical jumping process along crystalline (helical) regions of the polymer, and a transport process in the amorphous regions which is dependent on formation of fourfold coordination sites via mutual motion of ether oxygens from two or more polymer chains. The intrahelical jumping process may exhibit Arrhenius behavior, while transport in the amorphous regions should behave like a configurational entropy dominated process, showing a temperature dependence like T** minus **1**/**2e** minus **A**/**T** minus **T**O, where T//O is the equilibrium glass transition temperature.
