8μm Uncoated Bright Aluminum Foil

8μm Uncoated Bright Aluminum Foil is designed for use as a current collector in lithium-ion and sodium-ion batteries. It can be directly applied to NMC and NMA cathodes, as well as sodium-ion battery cathodes and anodes. The foil also serves as an excellent substrate for advanced surface treatments to meet the performance requirements of next-generation batteries. Our precision slitting lines ensure accurate and consistent aluminum foil widths from 200 mm to 1,700 mm to meet diverse customer requirements.
