Battery aluminum foil for ESS

The 8µm Ultra Clean Aluminum Foil is used for batteries undergoes an acidic cleaning process to remove oil residues and impurities during production, with no barrier coating applied. Compared to conventional aluminum foil, it imposes extremely stringent requirements on parameters such as thickness, strength, and surface cleanliness, aiming for the thinnest possible thickness, highest strength, optimal dyna value, and the most pristine surface quality.
