In this work, a simple and cost-effective two-step ball-milling method was proposed to fabricate Si/SiOx/C composites by using commercial SiO and graphite carbon as raw materials. The two-step ball-milling synthesis of the Si/SiOx/C composites can avoid the generation of an inert SiC phase and realize the uniform dispersion of Si/S
