Published: July 29, 2024

Sodium-ion batteries (SIBs) with abundant sodium resources have been considered to be competitive candidates for large-scale energy storage systems. However, undesirable instability of the electrode/electrolyte interface (EEI) at electrode surface in a commercial ester-based electrolyte results unsatisfactory electrochemical performance SIBs. Herein, robust sulfur-containing inorganic-rich EEI is simultaneously constructed on both Prussian blue (PB) cathode and hard carbon (HC) anode via film-forming additive, named sulfolane (SL). SL largely participates inner Na+ sheath, weakening coordination Na+-solvent accelerated desolvation inducing additive-derived interfacial chemistry. These merit improved reversible capacity, rate performance, cycling stability HC||PB full cell SL-containing electrolyte.

Abstract Sodium‐ion batteries (SIBs) hold tremendous potential in next‐generation energy storage. However, no SIB has yet achieved simultaneous support for high voltage, rapid charging, and all‐climate adaptability due to electrolyte limitations.
