This product is designed for high-capacity lithium battery applications, particularly in the 3C sector, where it serves as an anode material with a specific capacity of 450 mAh/g. The silicon carbon alloy features excellent processing performance and low cycle expansion, addressing common challenges in silicon-based anodes. To optimize electrochemical stability and cycling performance, it is recommended to incorporate 0.5–2% CNT into the formula, increase the electrolyte additive dosage relative to graphite anodes, and use specialized PAA-series binders. These measures help mitigate the poor SEI film formation typical of silicon anodes. Suitable for high-capacity polymer and cylindrical batteries, this material is intended for both research and practical application in advanced lithium-ion systems.
