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

In order to make spherical, graphite processing possible, the dry graphite concentrate must first be crushed and trimmed. Then it is magnetically separated by the spherical diagramite workshop, where it will become the original product, spherical, after purification at high temperatures.

The battery industry uses spherical Graphite

The global market for graphite flake continues to expand as more people realize the benefits of energy storage.

Spherical graphite

This is crucial for efficient operation of LiB lithium-ion batteries. The key ingredient of LiB’s anode is sphere graphite. A LiB without it would cease to function.

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 the recharge capacity.

LiB will require different Spherical Graphite sizes, as Spherical Graphite’s particle size affects the LiB performance. i.e. A tiny Spherical Graphite atom, d50 10 microns, could be used for a LiB which has fast-charging requirements. But, a LiB batteries with large power needs would need a bigger Spherical Graphite atom, 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 purifying the graphite. 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

Spherical Graphite

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.
