The electrochemical performance of lithium-ion batteries (LIBs) is plagued by sluggish interfacial kinetics. Fortunately, the Li solvation structure bridges the bulk electrolyte and interfacial chemistry, providing a pathway for promoting electrochemical kinetics in LIBs. Herein, we improve the interfacial kinetics by tuning the Li coordination chemistry based on solvent molecular engineering.

Article Synopsis
- "Solvent-in-salt" electrolytes show potential for improving lithium metal batteries (LMBs), but their slow lithium transport limits performance.
- Researchers discovered a "tug-of-war" effect in the solvation sheath that enhances the rate capability by balancing different interactions between solvents and lithium.
- The newly developed electrolytes achieved high lithium transport efficiency and impressive cycling stability in various battery configurations, indicating a path towards higher energy-density and performance in LMBs.
