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; 

Set up in 2000, Henso Ltd is specialized in producing and selling graphite and carbon materials, as well as other related products. Our plant is located in Pingdu city, and we have about 300 staff and tens of technicains. Our products include natural crystalline graphite, graphite flakes, ultra fine graphite powder, expandable graphite, nano graphite powder, amorphous graphite, synthetic graphite, graphite rods and carbon powder, etc. Till 2002, Henso has grown into one of the leading supplier of natural graphite in China. The total production capacity is 20000mt per year.

We are ISO9001 certified company, and quality is the first, which is our guideline.
