Aluminum-plastic film is the packaging material for soft-pack lithium batteries. It is a multi-layer film composed of outer nylon layer/adhesive/middle aluminum foil/adhesive/inner heat sealing layer. Aluminum-plastic film has high barrier properties It has the characteristics of good cold stamping formability, puncture resistance, electrolyte stability, high temperature resistance and strong insulation.

As lithium batteries are used more and more widely, the demand for raw materials has skyrocketed, and at the same time, higher requirements have been placed on the safety of lithium batteries. In the three-layer structure of the aluminum-plastic composite film, aluminum foil is used as the middle layer. Generally, 8021 aluminum foil and 8079 aluminum foil are used. It mainly prevents the penetration of water vapor outside the battery and prevents the leakage of internal electrolyte. The performance of aluminum foil is good or bad. Determines the safety and service life of the product.
