Expanded graphite


Lithium battery field

As a kind of high purity carbon material, spherical graphite has good deintercalation, electrical conductivity and chemical stability, so it is widely used in the field of lithium batteries. At present, spherical graphite has become one of the main raw materials for the manufacture of anode materials. Compared with traditional natural graphite and artificial graphite, spherical graphite has the advantages of uniform particle size, large specific surface area and high particle roundness, which makes it have a wide range of applications in the field of lithium batteries.

Precision casting field

Spherical graphite has been widely used in the field of precision casting because of its excellent lubrication performance, high wear resistance and no adhesion. In the casting process, the use of the lubrication characteristics of spherical graphite can reduce thermal cracking and deformation, and improve the quality and forming rate of the product. At present, spherical graphite has become a common additive for cast steel and cast iron.
