Aluminum Laminated Film For Pouch Cell Case

Laminated aluminum film is a material in which multiple layers of aluminum foil are stacked together and laminated by hot pressing. It has high strength, electrical conductivity and corrosion resistance, and is widely used in electronics, electricity, communications and other fields. The manufacturing process of laminated aluminum foil is relatively complex and requires multiple processes, such as gluing, lamination, hot pressing, etc. During the manufacturing process, factors such as the thickness, surface quality, and amount of glue applied on each layer need to be controlled to ensure the performance and reliability of the final product.

Laminated aluminum film for pouch cell case offers a range of excellent properties.

1. It has extremely high barrier properties, which can effectively block moisture, oxygen and other harmful substances in the external environment, and protect the electrochemical system inside the battery.
2. Laminated aluminum foil has good formability and electrolyte resistance, can adapt to various complex battery shapes, and can maintain stable performance during battery use.
3. It also has the characteristics of high temperature resistance and puncture resistance, which can improve the safety performance and service life of the battery.

In pouch batteries, laminated aluminum film is mainly used as a structural layer to protect and isolate the internal materials of the battery. It can provide good mechanical protection and thermal stability, and can block harmful substances in the external environment. At the same time, the surface quality, thickness, glue coating amount and other factors of the laminated aluminum foil will affect its barrier performance and sealing performance, so these parameters need to be strictly controlled during the manufacturing process.
