Polymer-derived carbon, which offers numerous sites for lithium storage, has emerged as a promising alternative to meet the increasing demand for high-energy density batteries. In this study, we investigated polymer pyrolyzed carbon and nano-silicon composites prepared through three methods: liquid-phase mixing (SiC-L), ball mill blending (SiC-S), and further milling with graphite (SiCG). By optimizing the silicon-to-carbon ratio (1:9, 2:8, 3:7, and 4:6), core–shell structured composites Si<sub>20</sub>C<sub>80</sub>-L and Si<sub>20</sub>C<sub>80</sub>-S with an optimal 2:8 ratio were obtained. The Si<sub>20</sub>C<sub>80</sub>-S anode delivered a reversible capacity of 471 mAh g<sup>−1</sup> after 200 cycles with a 56% expansion rate. Incorporation of flake graphite produced a hierarchical silicon–carbon–graphite composite (Si<sub>20</sub>C<sub>60</sub>G<sub>20</sub>), achieving 500 mAh g<sup>−1</sup> after 200 cycles and reducing the expansion rate to 34%. The improved performance arises from carbon matrix confinement of silicon and an optimized conductive network that enhances structural integrity and lithium storage. This study provides a feasible route toward scalable fabrication of high-stability silicon-based anodes for next-generation lithium-ion batteries.","PeriodicalId":12574,"journal":{"name":"Fullerenes, Nanotubes and Carbon Nanostructures","volume":"34 6","pages":"600-612"},"PeriodicalIF":0.0,"publicationDate":"2026-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147914752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
