Understanding the Effect of Lithium Ion Solvation Structures on the Stability of Li Metal Anodes Based on Molecular Properties

Опубликована: Янв. 1, 2025

The lithium deposition and SEI formation, which are crucial factors limiting the use of metal anodes with high specific energy, both closely related to ion-solvent coordination (ISC) structure ions. Nevertheless, there is a paucity knowledge at molecular level concerning link between stability Li anode ISC structure. Here, influence carbonate-based electrolytes different salt mole ratio (MR) on was investigated through dynamics (MD) simulations, density functional theory (DFT) calculations electrochemical experiments. mechanism effect constructed level. A significant correlation found electrostatic potential (ESP) solvation desolvation energy (Ed) low MR. Consequently, ESP can be employed as descriptor for experimental screening solvents. It also identified that Ed reduced increasing MR, thereby optimizing deposition. This study offers insights into pivotal function in formation provides an effective approach optimize fabrication stable lithium-metal batteries.
