Poly( p -benzoquinono)diimidazole-Linked Covalent Organic Framework as An Efficient Anode Endues Sodium-Ion Batteries with High Performance and Wide Temperature Adaptability

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…
