Spherical Graphite
Using flake graphite as raw material,taking unique shaping and grading technology, the product size range can be narrowed and the pages can be concentrated. Advanced screening and mixing technology can be used to control the foreign matter in the product to ensure the stability, uniformity and consistency of the product. Spherical graphite is the main raw material for lithium ion battery anode materials.
Product performance: high tap density, round surface, good sphericity, close to potato shape. The quality is stable and the particle size distribution is narrow, SSA=2.4-2.8.
