Avoiding dendrite formation by confining lithium deposition underneath Li–Sn coatings

The use of interfacial layers to stabilize the lithium surface is a popular research direction for improving morphology deposited and suppressing dendrite formation. This work considers different approach controlling formation where plated underneath an coating. In present research, Li–Sn intermetallic was chosen as model system due its lithium-rich phases high Li diffusivity. These coatings also exhibit significantly higher exchange current than bare thus leading better charge transfer kinetics. instrumental in determining whether deposition occurs above or below High-resolution transmission electron microscopy cryogenic focused ion beam scanning were used identify features associated with deposition. Atomic scale simulations provide insight adsorption energies
