8021 Aluminum Foil Contributes a lot to Battery Safety

With the upgrading of electronic products, as well as the consumption of new energy vehicles led, the demand for polymer lithium batteries is increasing. Electronic products and new energy vehicles have gradually increased the requirements for battery safety, storage capacity, weight, etc., and also stimulated the consumption of aluminum plastic film materials - aluminum foil.

Aluminum foil is an important part of aluminum-plastic composite film, usually use 8021 aluminum foil, 8079 aluminum foil material as the intermediate layer, the aluminum foil mainly serves to prevent the infiltration of moisture outside the battery and to prevent the leakage of the internal electrolyte. The use of aluminum plastic film as the battery casing does not cause problems such as battery leakage, explosion, etc. The product is safer, lighter and thinner, and the specific capacity and weight of the battery are greatly improved.
The safe operation of lithium batteries has high requirements for aluminum foil performance:

1, Extremely high barrier properties;

2, good cold stamping formability;

3, puncture resistance and high stability.
