Production Process Overview
Mining
Graphite is extracted from natural deposits through surface or underground mining. The raw ore is typically mixed with other materials, requiring further processing.
Flotation
The mined graphite ore undergoes froth flotation, where water and chemicals separate the graphite from impurities. This results in a concentrate containing higher graphite purity.
Chemical Purification
The graphite concentrate is chemically treated (often with acids) to remove remaining impurities. This step increases purity to 99.95% or higher, required for battery-grade graphite.
Micronization
The purified graphite is ground into fine particles to meet the size specifications for battery applications. This improves the material's suitability for further processing.
Spheronization
The graphite particles are shaped into spherical forms to increase packing density and improve conductivity in the battery anode. Spheronization enhances the material's electrochemical performance.
Coating
The spherical graphite is coated with a carbon layer, which enhances its conductivity and stability during battery cycling. This coating also protects the graphite from side reactions.
Thermal Purification
In a high-temperature furnace, any remaining impurities are vaporized, achieving ultra-high purity (>99.99%). This step ensures the graphite meets stringent quality requirements for battery applications.
