How is Spherical Graphite C Powder produced?
Spherical graphite is produced through fine grinding, purification and sterilization. It is made of flake graphite concentrate produced from graphite ore.
Generally, flake graphite is shaped into a spherical shape by a mechanical grinding process. The round shape of graphite allows particles to be more efficiently accumulated in the LiB anode, thereby increasing the energy and charging capacity of LiB.
Then the spheroidized graphite is purified to eliminate harmful elements, including SiO2, Fe, S and other metal elements. Various purification techniques are used. These measures include the use of hydrofluoric acid for active acid purification and the use of high-temperature furnaces for thermal purification. Both methods have their advantages and disadvantages.
Active acid purification is a means and an effective purification method, but due to the nature of the acids used (including hydrofluoric acid), there are toxic and dangerous working environments and environmental management challenges. Thermal purification is an electric heating process. Compared with acid purification, it is very expensive, but it is very safe and does not affect the environment.
After purification, please use purified spherical graphite to help improve the surface area and surface area of the particles. Many LiB manufacturers use their own proprietary technology for coating.
The purified spherical graphite is then packaged into the anode shape required for LiB batteries.
