Significant volume expansion and limited electrical conductivity pose substantial challenges to the practical application of silicon (Si). Herein, nanoparticles are incorporated into a dual‐carbon matrix co‐doped with nitrogen sulfur (N/S Si/G/C) using method that combines ball milling carbonization. The Si uniformly distributed between graphite layers encapsulated by an amorphous carbon layer N/S generated from pyrolysis pitch thiourea. This three‐dimensional structure not only effectively mitigates but also significantly enhances material's ionic electronic conductivity. Even at current density 1 A g −1 , capacity remains 625.87 mAh after 500 cycles, demonstrating exceptional cycling stability. When assembled full battery LiFePO 4 retains 158.9 200 corresponding retention 95.6%. In addition, is simple operate, highly adaptable versatile in function, does involve any toxic or harmful chemical substances, providing new idea for industrial production silicon–carbon anode materials.
