We report the easy synthesis of interconnected carbon spheres by a polymerization reaction between <em>p</em>-benzaldehyde and 2,6-diaminopyridine. The synthesis involves adjusting the mass ratio of the copolymer and KOH activator to achieve increased charge storage ability and high energy output, which are attributed to the high ion-accessible area provided by the large number of micropores, high N/O contents and rapid ion diffusion channels in the porous structure. At a PMEC∶KOH mass ratio of 1∶1, the high electrolyte ion-adsorption area (2599.76 m<sup>2</sup> g<sup>−1</sup>) and the N/O dopant atoms of the conductive framework of a typical carbon electrode produce a superior specific capacity (303.2 F g<sup>−1</sup>@0.5 A g<sup>−1</sup>) giving an assembled symmetric capacitor a high energy delivery of 11.3 Wh kg<sup>−1</sup>@250 W kg<sup>−1</sup>. This study presents a simple strategy for synthesizing microporous carbon and highlights its potential use in KOH-based supercapacitors.</div><div><span><figure><span><img><ol><li><span><span>Download: <span>Download high-res image (53KB)</span></span></span></li><li><span><span>Download: <span>Download full-size image</span></span></span></li></ol></span></figure></span></div></div>","PeriodicalId":19719,"journal":{"name":"New Carbon Materials","volume":"40 1","pages":"Pages 231-242"},"PeriodicalIF":5.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143610532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
