| Abstract Scope |
All solid-state batteries promise high energy densities as they will enable the elimination of graphite anode materials. A solid electrolyte makes it possible to plate and strip lithium metal between the current collector and the solid electrolyte. However, challenges persist as plating and stripping can lead to dendrite growth and void formation, respectively. To overcome these problems, new strategies exploit alloying reactions to control morphological evolution during lithium plating and stripping. Alloys of lithium with elements such as Mg, Al, Sn, Sb, Ag and In exhibit tremendously rich thermodynamic and kinetic properties. They host a wide variety of intermetallic compounds with unique anti-site defects and diffusion mechanisms. The statistical mechanics techniques that Prof. Wolverton has pioneered throughout his career are proving invaluable in elucidating the fundamental thermo-kinetic properties of lithium alloys. |
