However, its practical utilization is limited by its low intrinsic electrical conductivity and significant volume expansion during lithiation. To address these challenges, substantial efforts have been dedicated to developing silicon/carbon composites. Herein, we report a solvent-free approach for encapsulating nano Si in nitrogen-doped carbon (Si@NC). The nitrogen-doped carbon coating significantly improves the electrical conductivity and effectively accommodates the volume fluctuation of nano Si. The resulting Si@NC composite manifests an impressive reversible capacity of 915 mAh g –1 with decent cyclability. This scalable, cost-effective, and environment-benign synthesis, which is solvent-free and flammable gas-free, offers a viable approach for the construction of high-performance silicon/carbon anodes.
