Using the highest quality imported artificial graphite developed

Processing process of Spherical Graphite Powder:

In the process of Spherical Graphite Powder processing, firstly, the dry graphite concentrate is processed in the Spherical Graphite Powder workshop to form the initial product Spherical Graphite Powder through rough crushing, dressing, magnetic separation and other processes, and then enters the purification workshop to become Spherical Graphite Powder (high purity) after high-temperature purification.

Applications of spherical graphite:
Spherical Graphite Powder material has good conductivity, high crystallinity, low cost, high theoretical lithium intercalation capacity, low and flat charge-discharge potential and other characteristics. It is an important part of lithium ion battery anode material and a replacement product of lithium ion battery cathode material at home and abroad. It has excellent conductivity and chemical stability, high charge-discharge capacity, long cycle life and environmental protection. Used for high-end lithium ion prismatic, cylindrical polymer battery.
