Constructing All-Climate Hybrid Sodium Ion/Metal Batteries through Intersolvent Synergistic Effect
Rechargeable sodium ion batteries (SIBs) under extreme conditions are still limited by sluggish Na+ transport/desolvation kinetics and unstable electrode/electrolyte interface, thus leading to rapid capacity decay and a short lifespan. Herein, electrolyte engineering is proposed via solvent–solvent hydrogen bonding interaction between dimethyl sulfite (DMS) and glutaronitrile (GN) solvents for wide-temperature SIBs. The formed hydrogen bonding between DMS and GN solvents not only enhances the antioxidative ability of DMS but also simultaneously promotes the formation of a loose solvation structure by distancing DMS from Na+ ions, facilitating Na+ transport/desolvation kinetics. The well-designed electrolyte exhibits wide-temperature application from −55 to 60 °C in NaNi0.33Fe0.33Mn0.33O2 ||Na half cells, while the improved cycling stability with preactivated hard carbon anode is also obtained from −40 to 45 °C. This work sheds light on intersolvent synergistic effect for wide-temperature electrolyte design, specializing in regulating electrolyte thermodynamic and kinetic behavior.
