Scalable synthesis of SiOx/Spherical graphite composite via thermal plasma and ball milling for high-performance Lithium-ion battery anodes

Abstract In this study, SiOx/spherical graphite (SiOx/SG) composites were successfully prepared as high-performance anode materials for lithium-ion batteries through the combination of thermal plasma and ball milling approach. The thermal plasma method enabled the production of SiOx nanoparticles with controlled morphology and particle size, ensuring high purity and homogeneity. These nanoparticles were then uniformly dispersed into spherical graphite (SG) via ball milling, forming a composite with enhanced structural stability and electrochemical performance. The resulting SiOx/SG composite exhibited superior electrochemical properties, including high specific capacity, excellent cycling stability, and improved rate capability. This synergistic approach offers an efficient, scalable, and industrially viable route for developing advanced anode materials for next-generation lithium-ion batteries.
