Determination of Moisture and Ash in Carbon-Based Battery Materials

Graphite is the most widely used anode material in Lithium-ion batteries due to its low cost and favorable energy density. However, researchers continue to explore alternative Carbon-based materials and additives to enhance conductivity and overall performance. Traditionally, quality control has focused on ensuring that Carbon-based battery materials have minimal moisture and ash content. Excess moisture can severely degrade battery performance, reducing cycle life and discharge capacity. Elevated ash levels often indicate the presence of impurities, including metals introduced during mining or processing. Both parameters are critical for maintaining electrochemical performance and ensuring consumer safety.
