Summary: Lithium (Li)-metal batteries suffer severe capacity deterioration at extreme temperatures due to increased kinetic barrier of interfacial processes. This study quantitatively probes the interfacial kinetics in three different electrolytes and reveals that desolvation is the limiting step dominating the cell impedance and capacity at low temperature. The use of a 1,3-dioxolane-based electrolyte with tamed solvent-solute interaction facilitates fast desolvation and enables practical Li|LiNi0.5Co0.2Mn0.3O2 cells at -40 degrees C to retain 66% of room-temperature capacity and withstand fast charging rates. The barrier of desolvation dictated by solvent-solute interaction environments is quantitatively uncovered, and regulating this interaction emerges as a promising solution to low-temperature batteries.
