Sulfite-Based Electrolyte Chemistry with Ion–Dipole Interactions and Robust Interphase Achieves Wide-Temperature Sodium-Ion Batteries

at -60 °C. Eventually, the Ah-class pouch cell displays 0.64 A h with 56% capacity retention at -40 °C. In short, the introduced electrolyte formulation enhances the wide temperature operation of SIBs, shedding light on the development of all-weather systems.
