Suppressing Dendrite Formation through Au‐Driven Interfacial Engineering for Solid‐State Lithium‐Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A thin gold nanolayer on lithium metal enables stable and uniform lithium plating in solid‐state batteries, enabling nearly 1 year and 11 months of continuous operation. The conductive coating lowers interfacial resistance, suppresses dendrite growth, and improves cycling stability, attributed to homogeneous deposition of Li+ on the gold layer ...
