Abstract Scope |
In recent years, there has been a push towards using Li metal as anode materials in Li-ion batteries in order to extract more energy density. Li-metal anodes are generally unsafe due to the formation of dendrites that penetrate through the electrolyte, causing electrical shortage. To overcome this issue, there were some recent studies that proposed coating the anode with alloys of Li with various elements such as In, Bi, Zn, and As. These alloy coatings, while acting as a buffer layer, should facilitate fast diffusion of Li ions, and also be less prone to drastic phase transitions during charging/discharging. Using high throughput first principles calculations, in this work we explore various thermodynamic and kinetic properties of a wide range of Li-alloys that show promising behavior. |
