Sodium-ion batteries (SIBs) are potential alternatives in the postlithium electrification era. However, developing practical Na + storage devices that offer temperature resilience, high capacity, superior rate performance, and durability remains a significant challenge. Herein, a poly( p -benzoquinono)diimidazole-linked covalent organic framework (COF; named CityU-36), prepared through polycondensation between 2,3,5,6-tetraaminobenzoquinone (TABQ) and 4,4′,4″-(1,3,5-triazine-2,4,6-triyl)tribenzaldehyde (TFPT), showcases significant advantages in pushing up the ability of Na + storage and wide-temperature operability in SIBs. Thanks to its dense redox-active centers, structural robustness, uniformed porosities, and large surface area, CityU-36 exhibits an ultrahigh reversible capacity of 552 mAh g –1 at 0.1 A g –1, outstanding rate performance of 369 mAh g –1 at 8.0 A g –1, and exceptional long-term cyclability with 546 mAh g –1 at 5 A g –1 over 2900 cycles when used as an anode in SIBs. More importantly, the Na//CityU-36 device demonstrates all-weather working potential and exhibits wide temperature adaptability from −40 °C (321 mAh g –1 @0.03 A g –1 ) to 60 °C (357 mAh g –1 @10 A g –1 ). These attributes position CityU-36 as a superior candidate among advanced forthcoming practical SIBs.
