The thickness range of 8021 aluminum foil production is 0.018mm-0.2mm, and the width can be controlled within 100-1650mm according to customer requirements. 8021 aluminum foil has good deep drawing performance, good electrolyte corrosion resistance, and high heat seal strength. It is a battery The preferred aluminum material for soft-clad aluminum foil.
The battery soft pack foil is used in various types of lithium batteries such as soft pack lithium batteries and polymer lithium batteries. The battery soft pack foil is a polymer shell covered with a liquid lithium ion battery.
The soft pack battery is made of plain aluminum foil (8021 alloy 0.04mm thickness), plastic film, and special glue. It is called aluminum-plastic film, and the plain aluminum foil (1235/1060/1070 pure aluminum 0.012-0.016mm thickness) is coated on the surface. There are ternary materials of lithium iron phosphate and lithium manganate, which are made into the inner core of the soft pack battery, and the finished inner core is placed in the finished aluminum-plastic film to make the battery for the electronic products that everyone uses every day. Many lead-acid batteries are what we call lithium batteries. The soft pack battery is structured with aluminum foil packaging. In the event of a safety hazard, the soft pack battery will only swell and crack at most, unlike the steel shell aluminum shell battery cell that will explode.
