Investigation of Structure and Ion Dynamics of a Lithium Ion Conducting Borophosphate Glass

Abstract

Lithium ion conducting borophosphate glass has been synthesized by melt quenching technique. The thermal and structural characterizations of the glass have been performed. The glass is structurally and thermally stable which is suitable for its applicability as glassy electrolyte for solid state batteries. The detailed investigation of the ion transport mechanism has been performed by employing conductivity spectroscopy measurements. The conductivity of the glass is moderate in room temperature but can be increased up to 3×10-6 Ω 1cm-1 at 413 K which predicts its application in high temperature battery application. The frequency and temperature dependent conductivity data have been analysed in the context of Jonscher model and random barrier model.
