However, the synthesis of COFs with abundant active sites, excellent stability, and increased conductivity remains a challenge. Here, chemically stable fully sp<jats:sup>2<\/jats:sup> carbon\u2010conjugated COFs (sp<jats:sup>2<\/jats:sup>c\u2010COFs) with multiple active sites are designed by the polymerization of benzo[1,2\u2010b:3,4\u2010b\u2032:5,6\u2010b\u2032\u2032]trithiophene\u20102,5,8\u2010tricarbaldehyde) (BTT) and s\u2010indacene\u20101,3,5,7(2H,6H)\u2010tetrone (ICTO) (denoted as BTT\u2010ICTO). The morphology and structure of the COF are precisely regulated from \u201cbutterfly\u2010shaped\u201d to \u201ccable\u2010like\u201d through an in situ controllable growth strategy, significantly promoting the exposure and utilization of active sites. When the unique \u201ccable\u2010like\u201d BTT\u2010ICTO@CNT is employed as lithium\u2010ion batteries (LIBs) cathode, it exhibits exceptional capacity (396\u2005mAh\u2009g<jats:sup>\u22121<\/jats:sup> at 0.1\u2005A\u2009g<jats:sup>\u22121<\/jats:sup> with 97.9\u2009% active sites utilization rate), superb rate capacity (227\u2005mAh\u2009g<jats:sup>\u22121<\/jats:sup> at 5.0\u2005A\u2009g<jats:sup>\u22121<\/jats:sup>), and excellent cycling performance (184\u2005mAh\u2009g<jats:sup>\u22121<\/jats:sup> over 8000\u2005cycles at 2.0\u2005A\u2009g<jats:sup>\u22121<\/jats:sup> with 0.00365\u2009% decay rate per cycle). The lithium storage mechanism of BTT\u2010ICTO is exhaustively revealed by in situ Fourier transform infrared, in situ Raman, and density functional theory calculations. This work provides in\u2010depth insights into fully sp<jats:sup>2<\/jats:sup>c\u2010COFs with multiple active sites for high\u2010performance LIBs.<\/jats:p>","DOI":"10.1002\/anie.202412334","type":"journal-article","created":{"date-parts":[[2024,7,24]],"date-time":"2024-07-24T12:29:48Z","timestamp":1721824188000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":68,"title":["Fully sp<sup>2<\/sup> Carbon\u2010Conjugated Covalent Organic Frameworks with Multiple Active Sites for Advanced Lithium\u2010Ion Battery Cathodes"],"prefix":"10.1002","volume":"63","author":[{"given":"Ning","family":"Fu","sequence":"first","affiliation":[{"name":"School of Chemical and Environmental Engineering Anyang Institute of Technology  Anyang 455000 P.
