8021 8079 Battery Pouch Foil

       Aluminum plastic film and aluminum foil material for pouch battery

　　Benefiting from the development of consumer electronics and new energy automobile industries, the demand for soft pack batteries continues to rise. As a kind of power battery, the pouch battery is packaged with aluminum-plastic film. It has the characteristics of large capacity, light weight, high density, less heat generation, and low internal resistance, and is welcomed by the market.

　　8021 Battery Pouch Foil

　　In pouch batteries, battery pouch is a critical and technically difficult material. The battery pouch is mainly composed of nylon layer, aluminum foil layer, heat-sealing layer and adhesive. Aluminum foil is the core material. 8021 aluminum foil is commonly used, and the thickness is in the range of 0.035-0.055mm. The material has a strong barrier ability, which mainly prevents the penetration of water vapor from the outside of the battery and prevents the seepage of the internal electrolyte.

　　Advantages and applications of pouch batteries

　　The structure of the pouch battery is packaged with aluminum-plastic film. In the event of a safety hazard, the pouch battery will at most only blow up and crack, and will not explode. Compared with lithium batteries, it has many advantages such as small size, light weight, high specific energy, high safety, and flexible design.

　　At present, soft-pack lithium batteries are mainly used in the 3C field. The main electronic products in my country’s consumer electronics market, such as notebook computers, mobile phones, cameras, etc., have relatively mature market development, and the demand for soft-pack lithium batteries remains stable. In addition, the penetration rate of soft-pack lithium batteries in the field of power batteries is also increasing.
