Whatever your unique requirements for spray drying lithium battery materials, GEA has the solution

GEA delivers advanced atomization technologies tailored to the evolving needs of the battery industry, focusing on materials such as Lithium Iron Phosphate (LFP) for cathodes, silicon and graphite-based compounds for anodes. With a focus on energy efficiency, precise particle size control and scalability, GEA ensures consistently high-quality material production.

Rotary atomization for cathodes

GEA’s Rotary Atomizer is the go-to solution for cathode materials, such as LFP. It handles high feed rates with low energy use, making it ideal for large-scale production. Designed to process abrasive feedstocks common in cathode material processing, the Rotary Atomizer also minimizes maintenance and enhances equipment lifespan.

Benefits include:

• Versatility: Handles various feed types and particle sizes in both open and closed cycle designs.
• Cost-effective: Ideal for producing quality powder in standard applications like LFP battery materials.
• Energy efficient: Uses less energy than other methods for small particle production.
• Robust design: Abrasive-resistant wheel reduces metal contamination, ensuring high-quality powder.
• Scalable: Test data supports easy scale-up for different production capacities.

COMBI-NOZZLE® technology for anodes

The COMBI-NOZZLE® system, a hybrid of pressure and two-fluid nozzles, is ideal for producing uniform particles essential for high-performance anode materials like silicon and graphite-based compounds. It achieves target particle sizes directly, minimizing the need for post-processing. The result is a highly efficient, energy-saving solution that delivers excellent uniformity and performance for demanding lithium battery applications.

Key benefits include:

• High particle quality: Smaller particle size and narrow particle size distribution for better battery performance.
• Energy efficient: Despite its high energy consumption, it is more efficient than other nozzles for small particle production.
• Cost-effective for high-end use: Delivers performance for premium battery materials.
• Versatile: Handles various feeds and particle sizes for flexible production.

Two-Fluid Nozzle for fine particles

For applications requiring smaller particle size, GEA offers the Two-Fluid Nozzle for producing the fine powders needed in both cathode and anode material production. The Two-Fluid Nozzle offers precision and uniformity – perfect for when smaller particle sizes are required in smaller capacities.

Benefits include:

• High particle quality: Produces smaller, denser particles for better battery performance.
• Cost-effective for high-end use: Supports high-performance battery material production.
• Versatile: Adapts to various feeds and particle sizes for flexible output.
