This study dedicated to a novel method for synthesizing silicon-carbon (Si/C) and silicon dioxide-carbon (SiO2/C) nanocomposite anodes for lithium-ion batteries, utilizing industrial copper slags from the Almalyk Mining and Metallurgical Complex as a cost-effective source of SiO2. The synthesized nanocomposites address key challenges in lithium-ion battery anodes, including the volumetric expansion of silicon and its low conductivity, by leveraging the high lithiation capacity of silicon combined with the structural stability and conductivity of carbon. Amorphous SiO3 was extracted from copper slags via ammonium fluoride (NH4F) treatment and subsequently reduced to metallurgical-grade silicon through carbothermal reduction. The resulting SiO2/C and Si/C composites were thoroughly characterized using SEM, XRD, and electrochemical analyses, demonstrating improved electrochemical performance, favorable particle size distribution, and stability. This approach not only reduces material costs but also promotes environmental sustainability by repurposing industrial waste, offering promising candidates for high-performance lithium-ion battery anodes.
