Central-Atom-Differentiated Solvent Chemistry Enables Anion-Reinforced Solvation for Ultra-Long Cycling Ah-Level Sodium-Ion Pouch Cells.
Conventional carbonate-based electrolytes for sodium-ion batteries (SIBs) provide high salt solubility and high-voltage compatibility. However, their inherent Na+ solvation behavior and interfacial reactions remain largely governed by carbon-centered carbonate motifs, making it difficult to concurrently achieve rapid N...
