Solvation chemistry in liquid electrolytes for rechargeable lithium batteries at low temperatures

Year: 2025

Type: article

Abstract: Over the past few decades, significant advancements have been made in the development of low‐temperature liquid electrolytes for lithium batteries (LBs). Ongoing exploration of liquid electrolytes is crucial for further enhancing the performance of these batteries. Solvation chemistry plays a dominant role in determining the properties of the electrolyte, significantly affecting LBs performance at low temperatures (LTs). This review introduces solvation structures and their impact, discussing how these structures promote fast desolvation processes and contribute to the improvement of battery performance. Additionally, various solvent strategies are highlighted to refine solvation chemistry at LTs, including the use of linear and cyclic ethers/esters, as well as the role of functional groups within these solvents. The review also summarizes the impact of lithium salts containing organic/inorganic anions on solvation chemistry. Characterization techniques for solvent chemistry are discussed, providing a comprehensive analysis that offers valuable insights for developing next‐generation electrolytes to ensure reliable battery performance across a wide temperature range.
