Battery Aluminum Foil is used as a current collector for lithium-ion batteries. Typically, the lithium-ion battery industry uses rolled aluminum foil as the positive current collector. Lithium batteries usually have two types of cylindrical and square shapes. The interior of the battery adopts a spiral wound structure and is formed by a very fine and highly permeable polyethylene film separator material between the positive and negative electrodes.
Rolled foil thicknesses vary from 10 to 50 microns. Commonly used lithium battery pure aluminum foil has various alloy grades such as 1060, 1050, 1145, 1235, etc., and has states such as -O, H14, -H24, -H22, -H18.
Aluminum foil products for automotive power batteries have the characteristics of thin thickness, high strength, small thickness deviation, excellent plate shape, and clean surface.
