LiZnSO4F made in an ionic liquid: A ceramic electrolyte composite for solid-state lithium batteries

Abstract

Wrapped in IL: Solid electrolytes are key for safer lithium batteries. The novel LiZnSO4F fluorosulfate prepared by an ionic-liquid-assisted synthesis delivers high ionic conductivity at room temperature (see picture). The lithium-containing ionic-liquid layer tailors the ionic conductivity of inorganic composites by a surface effect. This finding can be useful in designing solid electrolytes with high ionic conductivity. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
