What is In Situ Formation of Liquid Metals via Galvanic Replacement Reaction to Build Dendrite‐Free Alkali‐Metal‐Ion Batteries about?
## Abstract Galvanic replacement reactions have been studied as a versatile route to synthesize nanostructured alloys. However, the galvanic replacement chemistry of alkali metals has rarely been explored. A protective interphase layer will be formed outside templates when the redox potential exceeds the potential windows of nonaqueous solutions, and the complex interfacial chemistry remains elusive. Here, we demonstrate the formation of room‐temperature liquid metal alloys of Na and K via galvanic replacement reaction. The fundamentals of the reaction at such low potentials are investigated via a combined experimental and computational method, which uncovers the critical role of solid‐electrolyte interphase in regulating the migration of Na ions and thus the alloying reaction kinetics. With in situ formed NaK liquid alloys as an anode, the dendritic growth of alkali metals can be eliminated thanks to the deformable and self‐healing features of liquid metals. The proof‐of‐concept battery delivers reasonable electrochemical performance, confirming the generality of this in situ approach and design principle for next‐generation dendrite‐free batteries.
