In this work, presents an approach to the utilization of agro-industrial and mining and metallurgical waste to obtain anode materials for lithium-ion batteries.Amorphous silicon dioxide (SiO₂) was synthesized from metallurgical waste by alkaline leaching, and highly porous activated carbon (AC) was obtained from rice husks by carbonization and activation with KOH.Based on these components, SiO₂/C composites with a developed texture and uniform structure were formed.Structural and morphological studies (XRD, SEM/EDS, nitrogen adsorption-desorption) confirmed the amorphous
