We can provide Battery Aluminum foils for Automotive vehicle, Bus, Cell phone, Electric tools &Apparatus etc. With a minimum thickness of 9 microns. Also we can do carbon coating on the surface of the Battery Aluminum Foil. The tensile strength of our high strength battery aluminum foil can reach 300N/mm2, with an elongation of more than 4%. Also the surface wettability can be more than 32dyne, surface flatness variation is less than 10I, both meet the industry highest standard.

Battery aluminum foil is used as a collector for lithium-ion batteries. Typically, the lithium ion battery industry uses rolled aluminum foil as a positive collector. The latest research of lithium ion battery industry found that the surface of aluminum (Al) alloy which is used as the positive collector of lithium ion rechargeable battery can be etched and roughened to improve the charge-discharge characteristics of the battery. Compared with the aluminum foil without surface treatment, the bonding force between aluminum foil and active substance after surface roughness treatment significantly improved the charge-discharge characteristics of the battery. This will play an important role in the development of rechargeable batteries for hybrid and electric vehicles, as well as rechargeable batteries for wind and solar power storage.
