Lithium ion conduction in rapidly quenched Li2O-Al2O3, Li2O-Ga2O3, and Li2O-Bi2O3 glasses

Abstract

Glasses containing Al₂O₃, Ga₂O₃, and Bi₂O₃ with Li₂O have been prepared by twin roller quenching. These glasses are found to exhibit reasonably high ionic conductivities and low electronic conductivities for Li₂O concentrations exceeding 50 mole %. The conductivity increases rapidly with increasing Li₂O content but does not differ greatly from system to system despite the large difference in the ionic radii of the trivalent cations, Al³⁺, Ga³⁺, and Bi³⁺ . A simple model for the behavior is discussed.
