However, the larger ionic radii and greater mass of Na\n                    <jats:sup>+<\/jats:sup>\n                    and K\n                    <jats:sup>+<\/jats:sup>\n                    ions often result in lower specific capacity, unsatisfactory rate performance, and diminished cycling stability. The advent of covalent organic frameworks (COFs) as electrode materials offers a promising avenue to address these challenges, given their robustness, uniform 1D nanochannels, and high structural designability. This review specifically summarizes the design principles for incorporating such dense redox\u2010active sites into COFs. We explore a diverse range of COFs featuring multiple redox units, including carbonyl (C\u2550O), imine (C\u2550N), and \u03c0\u2010extended aromatic electroactive centers, while correlating their structural characteristics with key electrochemical performance metrics such as capacity, kinetics, and cyclability in SIBs and PIBs. Moreover, we place particular emphasis on contributions from our own research group in this advancing field. Finally, we discuss the remaining challenges and propose potential solutions for the continued development of high\u2010capacity COF electrodes for SIB and PIB applications.\n                  <\/jats:p>","DOI":"10.1002\/chem.70934","type":"journal-article","created":{"date-parts":[[2026,3,25]],"date-time":"2026-03-25T13:17:17Z","timestamp":1774444637000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Packing Dense Redox\u2010Active Centers in Covalent Organic Framework Electrodes for High\u2010Performance Sodium\u2010 and Potassium\u2010Ion Batteries: A Review"],"prefix":"10.1002","volume":"32","author":[{"given":"Rui","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Materials and Chemical Engineering China Three Gorges University  Yichang Hubei P.
