Mill Finish Aluminum Foil for Lithium Battery

9μm Mill Finish Aluminum Foil is engineered to act as a current collector for lithium-ion and sodium-ion batteries. It is directly applicable to NMC and NCA cathodes, together with both cathodes and anodes of sodium-ion batteries. Additionally, the foil functions as an outstanding substrate for advanced surface modification treatments, satisfying the performance demands of next-generation batteries. Equipped with precision slitting equipment, we deliver aluminum foil with stable, precise widths ranging from 200 mm to 1,700 mm to accommodate varied customer specifications.
