Application of spherical graphite in the battery industry


What’s spherical-graphite?

Spherical graphite

This graphite product is made from high-quality natural flake graphite. The graphite is modified using advanced technology to make graphite products of different shapes and fineness, such as ellipses.


Spherical graphite


Spherical graphite has excellent electrical conductivity, good crystallinity and low costs. It also exhibits high theoretical lithium insert capacity and low charge and discharge potential. It plays an important role in the production of lithium-ion lithium battery batteries. Material replacement products. It is very good at electrical conductivity, chemical stability, high charging and discharge capability, as well as environmental protection.


Spherical graphite Preparation


The graphite dry concentrate must be first crushed and trimmed in order to make the initial product, which is spherical. It then goes through magnetic separation in the spherical diagramite workshop, where it will become high purity spherical.


The battery industry uses spherical Graphite


As the world transitions to clean energy, including electric cars (motor vehicle, passenger, and heavy transport), and home energy storage, global demand for energy storage options that are cost-effective continues to drive graphite flake’s growth.


Spherical graphite

This is crucial for efficient operation of LiB lithium-ion batteries. Spherical graphite, which is essential for the LiB’s anode to function properly, would be the missing component.

Spherical graphite is historically derived from synthetic graphite. It’s a more expensive alternative to natural flake graphite.

Flake graphite typically has a cylindrical shape that is formed by mechanical attrition. Spherical Graphite has a rounded shape that allows particles to be packed in a LiB, increasing the anode’s energy and recharge capacity.

LiB will require different Spherical Graphite sizes, as Spherical Graphite’s particle size affects the LiB performance. i.e. If a LiB has fast-charging requirements and a smaller Spherical Graphite component, d50 (10 microns), it would use it. A LiB battery with large power needs would need a bigger Spherical Graphite part, d50 (20 microns).

To remove any harmful elements, such as SiO2, Fe, S and other metals, the graphite spheroid is purified. There are many methods of purification. You can choose from aggressive acid purification by hydrofluoric acid or thermal purification that uses high-temperature ovens. These methods each have advantages and disadvantages.

Once purified, the Purified

The particles are coated in order to increase their surface area. Many LiB companies used their own coating technology.

Once the Spherical Graphite has been coated and purified, the material is packed in the form of anodes for LiB-battery batteries.

Spherical graphite’s suitability for Lithium-Ion Battery (LiB), applications has been confirmed by test work.
