Measuring Ionic Conductivity in Electrodes Prepared by Solvent-free Melt Extrusion

Abstract

Battery electrodes must simultaneously conduct electrons and ions to enable charge transfer to take place. Conductivity is conferred using a combination of ion-conducting polymeric binder material and electronically conductive carbon. This work presents a reproducible technique for measuring the ionic conductivity of electrodes made from formulations containing thermoplastic vulcanizates.
