상세 정보

This graphite material is developed for high-rate fast-charging applications in advanced lithium-ion battery research. As an anode-grade product, it exhibits a D50 particle size of approximately 9.0 µm with a narrow distribution, a BET specific surface area below 1.5 m²/g, and a tap density exceeding 1.0 g/cm³, supporting efficient electrode compaction. Electrochemical testing demonstrates an initial reversible capacity of 362.2 mAh/g and a first-cycle Coulombic efficiency of 92.7%, indicating good capacity retention and low irreversible loss. Low magnetic impurity levels (Fe+Cr+Ni+Zn at 0.06 ppm) further enhance its suitability for high-performance cell assemblies. The material is supplied as a black powder, vacuum-sealed in aluminum-plastic film, and should be stored in a cool, dry environment. It is commonly used in experimental studies focusing on fast-charging anode formulations and high-rate battery performance evaluation.
