Description：
It is produced from high-quality natural flake graphite as raw material through a process of (crushing - shaping - classification - chemical purification - pure water washing - drying - sieving - uniform mixing - fine sieving - demagnetization - packaging). The product has good stability, good sphericity, and effective control measures for impurities and foreign substances. The finished product can achieve high capacity and good cycle performance.
Variety:SG8 SG10 SG12 SG15 SG16 SG17 SG20 SG23 SG25
Performance: Strong chemical stability, high charge and discharge capacity, long cycle life, and good safety performance.
Usage: Mainly used in lithium-ion secondary batteries.
Classified by purity: 95-97 series natural spherical graphite, 99-998 series natural spherical graphite, 99.95 high-purity spherical graphite series.
Classified by particle size: SG20-SG25 large particle size spherical graphite series, SG15-SG19 medium particle size spherical graphite series, SG11-SG14 small particle size spherical graphite series, SG8-SG10 ultra-fine particle size spherical graphite series.
Advantage：
The product quality stability is high, and the error of the particle size result for 20 tons is within ± 0.2.
The specific surface area of products of the same level is relatively low, but the coating effect is better.
Excellent foreign matter control process, magnetic substances <0.1ppm.
It has stable chemical properties, high charge and discharge capacity, good cycle performance and excellent safety performance.
Application field：
Negative electrodes for ordinary capacity mobile phone batteries and small power tool batteries.
Negative electrode materials for power vehicle batteries.
The field of high-end high-density refractory bricks.
Technical indicators：
Products of purity 95-97-99 series can be produced according to customer requirements. It can also be customized according to the individual requirements of customers.
