Tóm tắt

Silicon-based anode materials experience significant volume changes and low conductivity during the lithiation process, which severely hinders their successful application in lithium-ion batteries. Reducing the size of silicon particles and effectively combining them with carbon-based materials are considered the main strategies to enhance the lithium-ion storage performance of silicon-based anodes. In this study, we employed a "bottom-up" strategy to synthesize Si@C anode materials by cross-linking octa-aminopropyl polyhedral oligomeric silsesquioxane (NH
