Cathode Material
GCL Tech's innovative and independently developed GCL-PHY One-step Physical Dry Process has achieved a breakthrough of utilizing no liquid raw materials and generating zero wastewater and waste gas during the synthesis of LFP materials. While resolving the environmental pain points of the traditional wet-process iron phosphate technology, the GCL-PHY process establishes core competitive advantages of a simpler process, lower cost, larger single-unit capacity, and higher degree of automation through the optimization of raw materials, processes, and equipment. This helps GCL Tech accelerate its stride toward a globalized, multi-product new energy materials platform.
Technical Advantages
The entire production process can be monitored in real-time through an intelligent MES system in the core central control room of the production workshop. The digitalized MES system can collect real-time production data from control points in various sections on-site to achieve centralized display, data organization, and analysis. It also implements loop control, parameter regulation, and signal alarming for process equipment in each section, making it an effective management tool for current LFP production workshops.
Mixing and Grinding
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.
Protective 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.
Crushing and 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.
