Stacking and Winding: Our stacking and winding technologies guarantee fast and precise assembly of battery electrodes. Whether pouch, prismatic, or cylindrical cells, our automated systems are highly accurate and efficient and reach the highest yield rates.

Can and Lid Production: ANDRITZ Schuler’s expertise in deep drawing and impact extrusion makes battery case production more efficient. Our automated lines produce high-quality prismatic and cylindrical cans, minimizing material waste while optimizing production line space and labor.

Electrolyte Filling: For electrolyte filling, our fully automated solutions ensure uniform distribution with minimal waste, enhancing battery consistency, safety, and overall functionality. The process maintains high accuracy even when handling large volumes, ensuring cleanliness throughout.

Complete assembly lines for lab & pilot scale: ANDRITZ Sovema provides comprehensive assembly lines for laboratory and pilot-scale applications, designed for pouch, prismatic, and cylindrical cells. These assembly lines are compatible with all major advanced cell chemistries, including specialized applications such as Li-Metal solid-state cell production. We offer high-precision manual lines for developing new advanced cells, flexible semi-automatic lines for validation in small batches, and fully automated lines for pilot production confirmation.

Shredding: Discharged batteries are either disassembled or directly fed into the ANDRITZ battery shredding tower, which includes a rotary shear pre-shredder and a granulator fine shredder. The system maintains an inert atmosphere using nitrogen to prevent fires or explosions, leveraging ANDRITZ's experience from fridge recycling.

Drying and Solvent Recovery: Shredded material undergoes vacuum drying below 80°C using Duesenfeld's patented low-temperature drying process to evaporate low-boiling solvents. A cooling system is employed to reclaim solvents and minimize environmental impact.

Off-Gas Treatment: The off-gas treatment system uses activated carbon filters to remove volatile organic compounds (VOCs) and other contaminants, ensuring compliance with environmental standards.

Separation and Sorting: The process involves multiple steps to separate heavy and light fractions, including black mass, electrode foils from aluminum and copper, and separator foils. This ensures high-quality output fractions.
