Dampening Lithium Charge Density by Clustering Solvents and Anions to Tame Lithium De‐Coordination Energy for Low‐Temperature Lithium‐Metal Batteries

ABSTRACT Sluggish lithium (Li) de‐coordination kinetics on the interface hinder the development of high‐energy and low‐temperature Li‐metal batteries (LMBs). In principle, weakly coordinated solvents and anions contribute to improved low‐temperature battery performances due to low Li de‐solvation and de‐anion energy barrier on the anode interface. However, extensive works employ strategies that go against the above‐mentioned principle, commonly using strong coordination strength solvents and anions to facilitate rate and cyclic performances. The in‐depth understanding of this refined Li coordination structure that accelerates Li redox kinetics remains rather elusive. To bridge such gap between theoretical…
