Abstract Covalent organic frameworks (COFs) hold great potential in sodium‐ion battery cathodes. However, most reported COF‐based electrodes show unsatisfying capacity and rate performance due to their limited redox site density, low crystallinity, poor conductivity. Herein, a highly crystalline robust donor‐acceptor type COF with abundant active sites is developed by the polymerization of donor unit benzo[1,2‐b:3,4‐b″:5,6‐b″']trithiophene‐2,5,8‐tricarbaldehyde) (BTT) acceptor s‐indacene‐1,3,5,7(2H,6H)‐tetrone (ICTO) (denoted as BTT‐ICTO) for cathodic Na + storage. The BTT‐ICTO‐graphene composites (BTT‐ICTO@G) synthesized situ growth have loose sheet structure rough surfaces, contributing improved conductivity utilization BTT‐ICTO. Benefiting from robustness BTT‐ICTO linked ethylene bonds, BTT‐ICTO@G cathodes exhibit high 325 mAh g −1 at 0.1 A 80%, excellent 190 5.0 , exceptional cycle performances 196 over 10 000 cycles 2.0 only 0.0015% decay per cycle.

Abstract Covalent organic frameworks (COFs) hold great promise as cathode materials for lithium‐ion batteries (LIBs), but their limited conductivity has hindered broader application. In this study, a novel metallosalen COF (Cu‐TH‐COF) is introduced, synthesized via one‐pot method, incorporating redox‐active Cu ions into N 2 O pockets and creating an extended π‐d conjugated structure. This design merges inorganic active sites, enabling efficient multi‐electron transfer improving the utilization of sites in LIBs. The conjugation significantly enhances electronic conductivity, resulting improved rate performance. As result, Cu‐TH‐COF delivers impressive discharge capacity 300 mAh g −1 at 50 mA retains 174 4000 , outperforming its Cu‐free counterpart. study demonstrates first time potential COFs high‐performance opens up new strategy next‐generation
