Currently, ether- and carbonate-based electrolytes have been extensively studied for applications in harsh conditions; however, it is difficult to develop a suitable electrolyte system that compatible with both high low temperatures. Herein, the first time, cyclic sulfite-based formulated successfully achieve wide-temperature operation of sodium-ion batteries (SIBs) from -60 60 °C. By precisely modulating ion-dipole interactions, dominant ion coordination states are screened directionally accelerate desolvation process simultaneously maintain sufficient electrostatic constraints, laying foundation high- low-temperature compatibility. And coordinated anions additives synergistically decompose enable inorganic-rich interphases robustness favorable diffusion, extending voltage window temperature range. As result, Na3V2(PO4)2O2F demonstrates 58 mA h g-1 at -50 °C while stably cycling 300 cycles 80% capacity retention. Additionally, Na3V2(PO4)3 NaFe1/3Ni1/3Mn1/3O2 cathodes also exhibit discharge specific capacities 50 65 Eventually, Ah-class pouch cell displays 0.64 A 56% retention -40 In short, introduced formulation enhances wide SIBs, shedding light on development all-weather systems.
