Determination of Sulfur and Carbon in Graphite and Carbon-Based Battery Materials

<p>The electrical conductivity of an anode material is closely linked to its Carbon content and structural purity. In particular, high-purity graphite (typically with a Carbon content exceeding 99.95 %) is preferred due to its superior electronic conductivity and consistent performance characteristics. Impurities within the graphite matrix, especially Sulfur, can significantly degrade conductivity and overall battery efficiency. Sulfur is commonly present in raw mined graphite and must be effectively removed during the refining process to ensure material quality. As such, precise determination of both Carbon and Sulfur content is essential for quality control, as these parameters directly influence the electrochemical performance and reliability of Carbon-based anode materials in lithium-ion batteries. </p>
