Technical advantages

The project adopts the unique and innovative GCL-PHY method to synthesize lithium iron phosphate materials. Compared to the traditional wet iron phosphate process, the GCL-PHY synthesis process has no liquid raw materials, no waste water or waste gas, which breaks through the pain points of the traditional lithium iron phosphate production and manufacturing process. At the same time, the GCL-PHY method has made exclusive innovations in process technology: changing raw materials, improving processes, and improving equipment, making the process simpler, the raw materials cheaper, the monomer capacity larger, and the degree of automation higher. It has great core competitiveness in the industry and has become GCL's new "black technology".

Mixing & Milling

Utilizing high-speed rotation, shear, and compression forces of raw materials and high-density zirconia grinding media within the milling chamber to mix materials more uniformly and grind them into impurity-free, near-spherical nanometer-scale particles. This can effectively reduce the primary particle size of the subsequently produced LFP and enhance its electrical performance.

Spray Drying

Utilizing the centrifugal force generated by a high-speed rotating atomizing disc to throw out and atomize the slurry, allowing the slurry to come into contact with hot air in the drying chamber and rapidly vaporize moisture. This process directly dries solutions or emulsions into powder or granular products, thereby eliminating the evaporation process.

High-Temperature Sintering

The core process of LFP production where high-purity nitrogen is introduced to maintain an inert environment to prevent product oxidation. Using graphite saggers as carriers, automated loading, constant-velocity heating sintering, cooling, and discharging cycles are carried out through a roller hearth kiln automated line. Benefiting from customized heating curves, its production capacity is increased by more than 40% compared to conventional equipment, and costs are effectively reduced.

Jet Milling & Packaging

Breaking up the agglomerates and cakes formed during the sintering process of LFP through jet milling to regulate a proper particle size distribution. Sealed packaging is conducted in a low-humidity environment to prevent moisture and oxidation, meeting the requirements of downstream battery cell enterprises for LFP materials.
