Weakly Solvating Electrolytes for Lithium and Post‐Lithium Rechargeable Batteries: Progress and Outlook

Advanced Energy Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 24, 2025

Abstract In the rapidly evolving global landscape of renewable energy sources, there is an increasing demand for high‐energy‐density rechargeable batteries essential storage. Simultaneously, a growing emphasis on developing high‐stability electrolytes. The concepts high concentration electrolytes (HCEs) and localized (LHCEs) have emerged, with notable progress achieved by altering cation‐solvent cation–anion solvation coordination environments. However, challenges persist, including costs low ionic conductivity. A recent development introduction weakly solvating electrolyte (WSE), which offers new perspective design stable at conventional or concentrations. This approach enables high‐performance modulating structure to generate unique anion‐driven interphase reaction chemistry. review outlines principles WSEs their operating mechanisms when applied lithium post‐lithium batteries. An outlook also presented future research directions WSE, coupled analysis technological challenges.
