Spherical graphite
This graphite product is made with high-quality natural flake graphite. It also contains advanced processing technology that allows for graphite products to be produced with different levels of fineness and elliptical shape. Spherical graphite has the properties of high electrical conductivity and high crystallinity.
Spherical graphite The processing principle is: First, you need to pulverize natural flake graphite powder to a size that can be used for particle size. Then, de-angularize the material so that it becomes ellipsoid, or spherical. The fine powder that is removed during this process can be separated and the normal distribution for spherical Graphite can then be obtained.
Selection criteria
spherical graphite, raw materials
The particle size of the spherical graphite material should be suitable. Too fine a particle size results in higher costs. A smaller particle size can affect the yield of spherical graphite. Additionally, too many auxiliary items will increase the price of raw materials. Study have shown that it is easier to use spherical-graphite-making raw materials with a particle size between -100 and -100 mesh.
A very important aspect of spherical-graphite raw materials is their carbon content. The carbon content of spherical graphite raw materials is a key factor. However, the more expensive the raw materials are, the lower the carbon contents. In turn, this will lead to an increase in purification passes and a higher total cost. It is composed of 95%-96% of raw materials and has the lowest comprehensive cost after practice and accumulation.
Selection criteria for spherical-graphite processing equipment
The airflow vortex-pulverizer is more used in the spherical processing. This has both the performance for pulverization as well as the ability to de-angularize. It is important to consider the quality of the equipment when selecting grading equipment.
Graphite anode material for lithium-ion batteries must be at least 99.95%. Purification is an essential part of the production process. Chemical purification is the most common method of producing high-purity, spherical graphite. Since the chemical raw materials used in the production process are strong acids, the purification equipment must be resistant to acid and corrosion. Chemical purification must be completed at a particular temperature. The equipment should also have a high resistance to heat.
After the chemical reactions, the impurities within the spherical graphite are dissolved into the reaction solution. Only then can the impurities be removed by washing. The most common washing equipment in this process is the filter press and centrifuge. The filter press offers many benefits, such as a higher recovery rate, low running material, low labor intensity and safety. However, it has a limited washing effect and can leave dead corners behind that cannot be washed. While the centrifuge offers more washing power and a more effective wash, it also has some drawbacks. Combining them works well.
The spherical Graphite after being washed is dried to remove moisture. It is also controlled below 0.5%. The most common problem with drying is secondary pollution. That is, after the spherical carbonite has been washed, it is dried to remove moisture. It is then dried to reduce the moisture level below 0.5%. Drying equipment such as the drying furnace, microwave dryer, and drying kiln are all used.
