Aluminum foil is a key material for heat dissipation in power battery manufacturing. This lightweight material has multiple functions in EV battery systems, resulting in a significant increase in demand for aluminum foil in recent years.
In the construction of electric vehicles, the battery is the most critical part. Aluminum foil, especially aluminum foil used as cathode material for lithium-ion batteries, that is, aluminum foil for current collectors in lithium batteries, is an important part of the battery. The main alloy component of this finishing aluminum foil product is pure aluminum 1XXX series, the thickness is between 0.010 and 0.020mm, and the state is H18. This high-purity, ultra-thin aluminum foil can increase the energy density of the battery and enhance the performance of the battery, so it plays an irreplaceable role in power battery manufacturing.
Aluminum foil is also widely used in other parts of electric vehicles, such as aluminum-plastic films for battery soft packages and tabs. In order to meet the special needs of the new energy vehicle market, new aluminum foil products such as carbon-coated foil and electro-etched foil have also been developed.
