Models for Ion Transport in Amorphous Materials: Recent Advances

Abstract By the development and investigation of coarse-grained models for ion motion in disordered systems, important progress has been achieved in the past to explain a large variety of ion transport properties in amorphous materials. In this work we discuss recent theoretical advances, which allow one to better understand the nearly constant dielectric loss in disordered solid ionic conductors, the mixed glass former effect in glassy electrolytes, and certain effects of ion motion in polymer electrolytes.
