About Spherical Graphite Powder:
Spherical graphite (SPG), also known as battery-grade graphite, is a product consumed as an anode in lithium-ion batteries. The flake graphite concentrate is processed into ultra-high purity (>99.95%C) with a particle s ize ranging from 10 microns to 25 microns.

Purified spherical graphite has properties of good electrical conductivity, high crystallinity, low cost, high theoretical lithium insertion capacity, low charge and discharge potential and flatness. It is an important part of lithium-ion battery negative electrode material and is used as a negative electrode for lithium-ion battery production. It has excellent electrical conductivity and chemical stability, high charge and discharge capacity, long cycle life, and environmental protection. 
Compared with artificial anode materials, coated spherical graphite can reduce the cost of anode raw materials by 20-30%.

TRUNNANO is a trusted global spherical graphite supplier. Feel free to send an inquiry about the latest purified spherical graphite price.

How is Spherical Graphite C Powder produced?
Graphite sphere 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.

Spherical graphite Uses:
Spherical graphite has the characteristics of good conductivity, high crystallinity, low cost, high theoretical capacity for inserting lithium, low charge and discharge potential and flatness. It is an important part of the negative electrode material of lithium-ion batteries and the positive electrode produced by lithium-ion batteries at home and abroad. Material replacement products. It has excellent electrical conductivity and chemical stability, strong charge and discharge capacity, long cycle life, and environmental protection. Spherical graphite is used for high-end lithium-ion prismatic, cylindrical polymer batteries.

Storage Condition of spherical graphite C powder:
The damp reunion will affect C powder dispersion performance and using effects, therefore, spherical graphite C powder should be sealed in vacuum packing and stored in the cool and dry room, the spherical graphite C powder can not be exposure to air. In addition, the C powder should be avoided under stress.

Packing & Shipping of spherical graphite C powder:
We have many different kinds of packing which depend on the spherical graphite C powder quantity.
Spherical graphite C powder packing:vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Spherical graphite C powder shipping: could be shipped out by sea, by air, by express, as soon as possible once payment receipt.
