However, the high solubility, poor electrical conductivity, and long activation time limit the development of organic materials in practice. Herein, two stable covalent organic materials with alkynyl linkage between benzene rings and benzothiadiazole groups with different amounts of fluorine atoms modification (defined as BOP\u20100F and BOP\u20102F), are designed for lithium\u2010ion batteries. Both BOP\u20100F and BOP\u20102F can achieve superior reversible capacities of \u2248719.8 and 713.5\u2005mAh\u2009g<jats:sup>\u22121<\/jats:sup> over 100\u2005cycles on account of the redox activity of alkynyl (two\u2010electron involved) and benzothiadiazole units (five\u2010electron involved) in these organic materials. While BOP\u20102F electrodes exhibit much more stable cycling performance than BOP\u20100F electrodes, especially without pronounced capacity ascending during initial cycling. It can be assigned to the synergy effect of alkynyl linkage and fluorine atom modification in BOP\u20102F. The lithium storage and activation mechanism of alkynyl, benzothiadiazole, and fluorine groups have also been deeply probed by a series of material characterizations and theoretical simulations. This work could be noteworthy in providing novel tactics for the molecular design and investigation of high\u2010efficiency organic electrodes for energy storage.<\/jats:p>","DOI":"10.1002\/anie.202316208","type":"journal-article","created":{"date-parts":[[2023,11,22]],"date-time":"2023-11-22T11:37:17Z","timestamp":1700653037000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Dendritic sp Carbon\u2010Conjugated Benzothiadiazole\u2010Based Polymers with Synergistic Multi\u2010Active Groups for High\u2010Performance Lithium Organic Batteries"],"prefix":"10.1002","volume":"63","author":[{"given":"Yingnan","family":"Cao","sequence":"first","affiliation":[{"name":"Department of Chemical Engineering School of Environmental and Chemical Engineering Shanghai University  99 Shangda Road 200444 Shanghai P.\u2005R.
