The spherical graphite process reduces the graphite raw material cost and improves negative anode performance. It is especially important in the context of the global transition to electric vehicles (EVs). The graphite anode is one of the most critical parts of a lithium-ion battery and represents up to 40% of its total cost, depending on the source. Coated Spherical Purified Graphite (CSPG) cuts the cost of this raw material by up to 20% and improves its electrochemical performance for lithium-ion batteries.

( Tech Co Ltd) has been in the field of spherical graphite for more than 12 years, and has been successfully developing spherical graphite processing technologies. Based on these technologies, the company has developed a spherical graphite production line and equipment systems that are fully automated, safe, economical, efficient and environmentally friendly.

The spherical graphite processing system consists of two pulverizer units that micronize and spheroidize the natural flake graphite. It also contains a multiple classification device and drying equipment. The multiple classification device can obtain five kinds of specification product (25,20,15,10,5 m m) and it has the characteristic of short preparation cycle, high finished products yield height, compact processing unit design, safety and environmental protection. The spherical graphite that has been classified is sent back to the Highefficientpulverizer for nodularization and multiple stage treatment. The mean residence time is 2-5 minutes, and it can obtain the spherical graphite with normal distribution (D50 3-35 m m). After that, it will pass through the efficient classification device for continuous classification so that the spherical graphite is enriched.
