8021 Aluminum Foil for Aluminum Composite Film High Barrier, High Elongation, High Stability
Soft pack batteries are made of aluminum foil (8021 aluminum foil), plastic film, and special glue bonded together, commonly known as aluminum-plastic film. Soft pack batteries in the structure of the aluminum foil packaging, in the event of a security risk, soft pack batteries at best will only be puffed and cracked, unlike the steel shell aluminum shell battery cells will not explode, security has been improved.
In the three-layer structure of aluminum-plastic composite film, aluminum foil, as the middle layer, mainly plays a role in preventing the penetration of water vapor outside the battery, while preventing the seepage of the internal electrolyte. In order to ensure the long-term stable and safe operation of the battery, the aluminum foil used in the aluminum-plastic film needs to have high barrier properties, good cold press formability, puncture resistance and stability.
The 8021 aluminum foil for aluminum composite film for flexible pack batteries has good elongation, good electrolyte corrosion resistance, and high heat sealing strength, and is commonly used in deep-drawn packaging materials, such as lithium soft pack batteries, lithium polymer batteries, and many other types of lithium batteries.
