Description

One important factor that could affects the Lithium-ion batteries and fuel cells production, is the slitting quality of their components such as electrode materials and PEM (Polymer Electrolyte Membrane / Proton Exchange Membrane). The slitting process must be precise, accurate and clean to avoid damaging the coating, the foil and the membrane.

Present on converting equipment manufacturing since 1955, Spoolex through its CALEMARD Machinery division gained a strong expertise in slitting and rewinding technology especially for sensitive materials. Our equipment allows to precisely slit wide web for producing strips of electrode and MEA components. Then, these strips are carefully rewound with no strip and material alteration, but also with straight wall and burr-free to ensure a highly productive and consistent production process for optimal performance batteries and fuel cells.

Materials slit on our flexible and reliable equipment:

🔋 Lithium-Ion Battery: Coated Aluminum Cathode | Coated Copper Anode | Copper Foil | Aluminum foil

🔋 Fuel Cell: Polymer Electrolyte Membrane – Proton Exchange Membrane | Carbon Fiber Non-woven or felt | PET foil

Thanks to our integrated R&D and Engineering department, we also offer 4.0 solutions for monitoring and productivity improvement processes, but also, fully or semi-automated solutions for loading/conveying/unloading operations.
