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 graphite’s surface and produce products of different shapes and fineness.


Application of spherical graphite


Spherical graphite is characterized by its good electrical conductivity. It is a vital component of lithium-ion cell negative electrode materials and is widely used in the production of lithium-ion cells at home and overseas. Material replacement products. It is highly durable, has a long life cycle, and has environmental protection.


Preparation spherical of graphite


After high-temperature separation, the graphite is purified to become spherical (high-purity) graphite.


Use of spherical carbon graphite for the battery industry


As the world moves towards a clean energy-based economy, encompassing electric vehicles for motor vehicles, heavy and passenger transport, and home energy storage systems, the demand for cost effective energy storage solutions is driving 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.

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 better recharge.

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 d50 values 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 by high-temperature ovens. Both methods have 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 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.
