Nano spherical conductive graphite

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.
