Using high-quality natural flake graphite as raw material, it is produced through the following processes: (milling-shaping-grading-chemical purification-pure water washing-drying-screening-average mixing-fine screening-demagnetization-packaging). The products have good stability, good potato shape, and contaminations are fully under control. The finished products can achieve high capacity and good cycle performance.

Classified by purity：95-97 series natural spherical graphite, 99-998 series natural spherical graphite, >=99.95 high purity spherical graphite series.

Classified by size：SG20-SG25 large-diameter spherical graphite series, SG15-SG19 medium-diameter spherical graphite series, SG11-SG14 small-diameter spherical graphite series, and SG8-SG10 ultra-fine spherical graphite series.
