Nevertheless, porous Si prepared via conventional reduction methods commonly undergoes structural shrinkage and uncontrollable pore configuration. Herein, a novel iron\u2010driven internal percolation mechanism is proposed to fabricate porous Si@C composites (p\u2010Si@C) through the ion exchange between Fe\u2010based Prussian blue templates and silicate anions, followed by low\u2010temperature molten\u2010salt aluminothermic reduction. The in\u2010situ formed Fe network acts as an electronic highway to accelerate the reduction of SiO\n                    <jats:sub>2<\/jats:sub>\n                    , while functioning as a sacrificial template to maintain a non\u2010shrinking topological framework with interconnected pores. Moreover, iron species catalyze the growth of graphitized carbon shells, inducing the formation of a LiF\u2010rich solid electrolyte interphase. Benefiting from the optimized structure, the p\u2010Si@C anode delivers a high reversible capacity of 605 mAh g\n                    <jats:sup>\u22121<\/jats:sup>\n                    at 8 A g\n                    <jats:sup>\u22121<\/jats:sup>\n                    , and the full cell paired with LiFePO\n                    <jats:sub>4<\/jats:sub>\n                    retains 95% of its capacity after 550 cycles. This work develops an innovative fabrication strategy for controllable porous Si based on the metal\u2010driven internal percolation mechanism, which can be extended to the rational design of other porous electrode materials.\n                  <\/jats:p>","DOI":"10.1002\/smtd.70951","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T09:39:16Z","timestamp":1786700356000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Iron\u2010Driven Internal Percolation Enables Topological Construction of 3D Interconnected Porous Si@C Anodes"],"prefix":"10.1002","volume":"10","author":[{"given":"Yanpeng","family":"Wang","sequence":"first","affiliation":[{"name":"Key Laboratory of Marine Equipment Materials and Protection of Shandong Province School of Materials Science and Engineering Ocean University of China  Qingdao Shandong P.
