| Abstract Scope |
Silicon Oxycarbide, a polymer-derived ceramic, a promising anode material for Li-ion batteries because of their thermal stability, tunable microstructure, and electrochemical performance compared to conventional graphite anodes. However, its broader application is limited by low electrical conductivity, low coulombic efficiency, and first cycle losses. Doping SiOC presents an effective strategy to address these limitations by enabling precise control over its microstructural, electrical and chemical properties. In this work, we investigate how dopant engineering and compositional modifications influence the structure, morphology, and electrochemical behavior of SiOC using structural characterization, electrochemical testing, and x-ray microscopy to analyze a series of modified SiOC anode composite. The results are expected to show that chemical modification through doping may enhance electrical conductivity and electrochemical performance, leading to improved cycle stability, higher coulombic efficiency, and reduced first-cycle losses. This study provides design insight into how modified SiOC anodes can be optimized for advanced Li-ion battery applications. |
