Mechanistic study demonstrates stable lithium plating via silver interlayers in anode-less solid-state batteries, suggesting design rules to inhibit dendrite formation.
. The Ag interlayer improved the interfacial stability enabled by Ag-dissolved Li, which inhibited dendritic growth, passing through the phase-separated Li-Ag alloy microstructure, while the other metals did not because of the Li plating at the Li-metal alloy/solid electrolyte interface. This work provides fundamental guidance for material selection and interface design, advancing the development of anode-less solid-state batteries.
