Abstract

Lithium metal batteries (LMBs) with fast‐charging capabilities can ease mileage anxiety, which is essential for the popularization of electric vehicles. However, the uncontrollable growth of Li dendrites and the repeated formation of electrode electrolyte interfaces lead to safety risks and low coulombic efficiency, which hinder the practical application of LMBs. Liquid electrolytes play an extremely important role in solving these problems. This review focuses on the recent achievements of liquid electrolytes for fast‐charging LMBs. The main factors limiting the fast transportation of Li ions are first introduced. The recent progress in electrolyte regulation for fast‐charging LMBs, including Li salts, electrolyte additives, and novel organic solvents, is summarized. Finally, a general conclusion and perspectives are proposed.
