What is spherical carbon?
Spherical graphite
It is made from high-quality, high-carbon flake graphite. A modern processing technique is used to change the surface of graphite in order to produce products with different shapes and fineness.
Applications of spherical graphite
Spherical graphite is characterized by its good electrical conductivity. It is an essential part of lithium ion battery negative material. It is used in the production of lithium ion batteries both domestically and internationally. Material replacement products. It is highly durable, has a long life cycle, a high rate of charge and discharge, and excellent electrical conductivity.
Preparation of Spherical Graphite
After high-temperature separation, the graphite is purified to spherical (high purity) graphite after it has been crushed, trimmed, magnetically separated, and spherical.
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. Anode components of LiBs are made of spherical Graphite. Without it, LiBs would not work.
Spherical Graphite is historically derived using synthetic graphite. It’s a much more expensive option than flake natural graphite.
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 purifications using high-temperature ovens. Both methods have their own advantages and drawbacks.
Purified after purification
Spherical Graphite
Coating is done to increase the surface and size 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 molded into the form of anodes for LiB Batteries.
Spherical Graphite (SGP) has proven itself to be a good material for Lithium-Ion Battery Applications.
