Lithium metal batteries utilizing lithium as the anode can achieve a greater energy density. However, it remains challenging to improve low-temperature performance and fast-charging features. Herein, we introduce an electrolyte solvation chemistry strategy regulate properties of ethylene carbonate (EC)-based electrolytes through intermolecular interactions, weakly solvated fluoroethylene (FEC) replace EC, incorporating low-melting-point solvent 1,2-difluorobenzene (2FB) diluent. We identified that interaction between 2FB facilitate Li

Abstract Lithium iron phosphate (LFP)/graphite batteries have long dominated the energy storage battery market and are anticipated to become dominant technology in global power market. However, poor fast‐charging capability low‐temperature performance of LFP/graphite seriously hinder their further spread. These limitations strongly associated with interfacial lithium (Li)‐ion transport. Here we report a wide‐temperature‐range ester‐based electrolyte that exhibits high ionic conductivity, fast kinetics excellent film‐forming ability by regulating anion chemistry Li salt. The barrier is quantitatively unraveled employing three‐electrode system distribution relaxation time technique. superior role proposed preventing 0 plating sustaining homogeneous stable interphases also systematically investigated. cells exhibit rechargeability an ultrawide temperature range −80 °C 80 outstanding without compromising lifespan. Specially, practical pouch achieve 80.2 % capacity retention after 1200 cycles (2 C) 10‐min charge 89 (5 at 25 provide reliable even °C.
