Thermodynamic and Kinetic Properties of the Lithium-Silver System.

ABSTRACT: A carbon-silver anode has recently been shown to suppress dendrite formation in all-solid-state lithium-ion batteries. The role that silver plays in enabling the reversible deposition and stripping of lithium remains unknown. Furthermore, very little is known about the thermodynamic and kinetic properties of Li _x Ag_1-x alloys. Here, we report on an in-depth first-principles study of phase stability and diffusion mechanisms in the Li-Ag alloy system. We identify two new intermetallic phases that are predicted to be stable in Li-rich Li _x Ag_1-x alloys with stoichiometries of Li₃Ag and Li₁₁Ag₂. Our calculations show that the peculiar and highly anharmonic energy surface of pure Li along th
