Formation of self-limited, stable and conductive interfaces between garnet electrolytes and lithium anodes for reversible lithium cycling in solid-state batteries

Abstract

Modification of the garnet-type solid electrolyte with a 10 nm Sn thin-film improves the contact and wetting performance between the garnet and the lithium metal and, thus enables fast and reversible lithium transport across their interface by forming a self-limited, conductive Li–Sn intermediate layer.
