China aluminum foil 1050 manufacturers can supply qualified aluminum foil for lithium batteries. Aluminum foil for lithium batteries is commonly used in current collectors for lithium batteries. In general, manufacturers of lithium batteries mostly use aluminum foil roll as the current collector. The thickness of the aluminum foil for lithium batteries ranges from 10 to 50 microns. The commonly used battery aluminum foil is mainly composed of 1000 series and 3000 series. The alloy grades mainly include 1060, 1050, 1235 and 3003 aluminum foils, etc., and the alloy state is O, H14, H18, H22, H24.
Why do lithium-ion batteries use aluminum foil as the positive electrode of the battery instead of copper foil? Both copper foil and aluminum foil can be used as current collectors. If aluminum foil 1050 is used as a negative electrode, aluminum is preferred to consume aluminum foil when it is discharged. This will destroy the battery and reduce the battery life. If the aluminum foil is used as the positive electrode of the battery, the lithium electronic battery can be protected, so the aluminum foil lithium battery has great advantages. China aluminum foil 1050 manufacturers provide high precision battery foil with clean surface and low tolerance, what’s more, the cost of 1050 aluminum foil is low and can save the cost of battery factory without any influence on the battery quality.
