Battery Aluminum Foil

　　Aluminum and aluminum alloy battery foils are current collectors for lithium-ion batteries. Usually, the lithium-ion battery industry uses rolled aluminum foil as the positive electrode of the battery aluminum foil as the negative electrode collector. 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.
