Graphex has expertise in the production and distribution of coated spherical graphite (CSG), used to form the Li-Ion battery anode. CSG is SG which has been further processed to enhance its cycle rate. The process includes pitch coating, carbonization, and demagnetization.
Our range of CSG is suitable for both electric vehicle power battery and 3C applications. Our CSG material is characterised by high specific capacity and coulombic efficiency.
