Spherical Graphite - Graphite

The spherical graphite is made from high quality graphite flakes. Its shape is like potato under microscope. This graphite has low specific surface area and high tap density. The tap density is above 1.0g/cc, while the SSA(BET) is from 3.5-8m2/g. Owning special characters, Spherical Graphite is mainly used as anode materials for Lithium ion rechargeable battery. The discharge capacity is above 360mAh/g, and cycle life is excellent.

Application:
i) negative materials for lithium ion battery;
ii) electrical conductive agent in carbon brush;
iii) pore former in ceramic membrane;
iv) heat-spreading materials;
v) filler for carbon and resin composite materials;
