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

With the increasing application of lithium batteries, the demand for raw materials has skyrocketed, and higher requirements have been placed on the safety of lithium batteries. In the three-layer structure of aluminum-plastic composite film, aluminum foil is used as the middle layer. Generally, 8021 aluminum foil and 8079 aluminum foil are used to prevent the infiltration of water vapor from the outside of the battery and the leakage of the internal electrolyte. The performance of the aluminum foil is good or bad. It determines the safety and service life of the product.
