Spherical graphite

Spherical graphite also known as battery-grade graphite, is the product that is consumed as an anode in lithium-ion batteries.

Description

All graphite grades and types for any solutions and any industries

Flake graphite concentrate is processed into ultra-high-purity (>99.95% C), microscopic (15 to 5 microns) spheres, which are used as a battery anode material.

This decreases the surface area, to allow more graphite into a smaller volume thus creating a smaller, lighter, more efficient anode product for the battery. It also increases the rate at which the cell can be charged.
