What is spherical carbon? Spherical graphite It is produced from high-quality natural flake graphite with high carbon content as the raw material. A modern processing technique is then used to modify its surface in order to create graphite products of different finenesses and shapes, such as ellipses.
Spherical graphite application
The flatness of spherical material graphite is a good combination of electrical conductivity and crystallinity. It has low cost, high theoretical insertion capacity and low charge potential. It is a key component of the negative electrodes for lithium ion batteries and is used in both domestic and international production. Material replacement products. It has excellent electrical and chemical conductivity, high charge-and-discharge capacity, long cycling life, and environmental protection.
Preparation spherical of graphite
After high-temperature separation, the spherical Graphite is produced by crushing, trimming, and magnetic separation in the spherical Graphite Workshop.

Use of spherical carbon graphite for the battery industry
As the world moves towards a clean energy-based economy, the demand for energy storage solutions that are cost-effective continues to drive growth in the graphite flakes market.
Spherical graphite The lithium-ion battery (LiB) is not able to function properly without this ingredient. Anodes of LiBs are made of spherical Graphite.
Spherical Graphite is historically derived using synthetic graphite. It’s a much more expensive option compared to natural flake.
A mechanical attrition is usually used to form flake graphite in a rounded and spherical shape. Spherical Graphite is packaged more efficiently in a LiB’s anode due to its rounded shape. This allows the LiB to have a higher energy capacity and recharge rate.
LiB requires different Spherical Graphite Particle Sizes as the Spherical Graphite Particle Size impacts the LiB’s performance targets. i.e. In a LiB which has a higher charging rate, a Spherical Graphite with a d50 value of 10 microns is used, while a LiB having a high power requirement would require a larger Spherical Graphite with a d50 value of 20 microns.
After purification, the spheroid is cleaned to remove any unwanted elements, such as SiO2, Fe or S. There are several purification methods. These include hydrofluoric and aggressive acid purifications, as well as thermal purification using high temperature furnaces. Both methods have advantages and drawbacks.
After purification the Purified Spherical Graphite Coating is done to increase the surface area of the particles. Many LiB producers used their proprietary technology to coat the particles.
The Spherical Graphite, which has been purified and coated, is then packed in the form of anodes for LiB Batteries.
Spherical Graphite (SGP) has proven itself to be a good material for Lithium-Ion Battery Applications.
