what is spherical graphite：
Spherical graphite is obtained from high-quality natural graphite through specific processes and processing. It has the characteristics of high purity, high crystallinity, high sphericity, uniform particle size, excellent conductivity, high charge and discharge capacity, long cycle life, and good safety performance. It is widely used in batteries, electronics, capacitors, semiconductors, aerospace, military, and other fields.
The production process of spherical graphite mainly includes mineral processing, purification, modification, molding, and other steps. Among them, beneficiation and purification are key steps to ensure the purity and quality of graphite, and modification is an important link to improve the oxidation resistance, high-temperature resistance, and chemical stability of graphite. During the modification process, the graphite surface is coated with a layer of organic matter, which can effectively improve graphite's oxidation and high-temperature resistance. At the same time, by controlling the modification process parameters, the thickness and density of the coating layer on the graphite surface can be adjusted, thereby controlling the chemical stability of graphite.
Spherical graphite has high conductivity and charge and discharge capacity, which can effectively improve battery energy density and cycle life. At the same time, it has high safety and will not produce harmful gases or burn, or other safety issues. Therefore, spherical graphite is an important part of the anode material for lithium-ion batteries and is also one of the important directions for future battery development.

Other fields: Besides the above application fields, spherical graphite is widely used to manufacture sealing materials, bearings, brake pads, pencil leads, etc. In these applications, spherical graphite's excellent performance and versatility are fully demonstrated.
Storage of spherical graphite：
1) spherical graphite should be stored in a dry, ventilated place where there is no other sources of pollution (recommended: temperature ≤ 45 ° C, humidity ≤ 85%);
2) spherical graphite should be neatly stacked, and the production batch number, date and other signs should be clearly identified;
3) spherical graphite should be carefully Handled during transportation to avoid the damage of the packaging; products that leak out of the package must not be returned to the box.
