corrosion resistant Aluminum battery foil

12μm Mill finish aluminum foil serves as a current collector for lithium-ion and sodium-ion batteries. It can be deployed directly with NMC and NCA cathodes, as well as cathodes and anodes for sodium-ion batteries. This aluminum foil offers a high-quality substrate for advanced surface treatment processes to meet the performance specifications of next-generation batteries. Our precision slitting lines guarantee consistent and accurate foil widths covering 200mm to 1,700mm, catering to a wide range of customer application requirements.
