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. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
