Silicon (Si) holds promise as an anode material for next-generation lithium-ion batteries due to its high theoretical capacity. However, practical applications are impeded by structural damage from volume expansion. Here, we designed a novel Si/CNFs/C integrating mesoporous Si particles, carbon nanofibers (CNFs), and quantum dots into three-dimensional (3D) architecture via one-step magnesiothermic reduction process. This design significantly enhances both electron ion conductivity, alleviates the expansion of ensures mechanical stability during battery operation. Consequently, with exhibit reversible capacity 1,172.4 mAh g-1 after 200 cycles at 0.1 A maintain 1,107.7 1,000 1 g-1. Notably, current density g-1, remains nearly comparable that 100 attributed significant pseudocapacitive characteristics facilitate performance under elevated densities. Furthermore, employed distribution relaxation times analysis alongside other electrochemical techniques investigate changes in transport pathways evolving role energy storage Our provide valuable insights optimizing 3D conductive architectures understanding dynamic mechanisms Si-based anodes, advancing development high-performance batteries.
