Title: Effect of salt and filler concentration on the conductivity and electrochemical stability of composite polymeric electrolytes

Abstract

Various composite polymeric electrolytes based on low as well as high molecular weight polyethers have been studied. The effect of the addition of various inorganic fillers on changes in ion-ion and ion-polymer interactions has been analyzed on the basis of impedance spectroscopy, FT-IR, DSC and rheological data. The addition of fillers results usually in an enhancement of conductivity, particularly in the ambient and sub-ambient temperature region. It is, however, demonstrated that for a variety of amorphous systems this conductivity enhancement is limited to the salt concentrations for which strong ionic association is also observed. As is indicated from infrared and conductivity experiments, the interaction between inorganic fillers and alkali metal salt polyether complexes results in the reduction in ionic association as well as a decrease in the crosslink density of polyether chains being the effect of complexation with alkali metal salts. Moreover, it is shown from impedance experiments that the addition of fillers results in the limitation in the formation of passive layers on the polyether--lithium electrode interface. It is demonstrated that the growth of the resistance of the secondary passive layer is related to the structure and interaction within the bulk of composite electrolytes. The effect of ionic associationmore » on the formation and growth of secondary passive layers is discussed.« less
