The latest research in the lithium ion battery industry has found that by etching and roughening the surface of the aluminum (Al) alloy foil used as the positive electrode collector of the lithium ion rechargeable battery, the charge and discharge characteristics of the battery can be improved. Compared with the aluminum foil without surface treatment, the bonding strength of the aluminum foil after the surface roughening treatment and the active material has significantly improved the charge and discharge characteristics of the battery. This has an important role in the development of rechargeable batteries for hybrid and electric vehicles, as well as rechargeable batteries for power storage of wind power and solar power.
