Soft packaging material for lithium battery-aluminum foil

The soft packaging lithium-ion battery uses an aluminum-plastic composite film, which is similar to a polymer lithium-ion battery, as a battery shell, replacing a steel or aluminum shell of a common lithium ion battery. Soft packaging material for lithium battery Includes aluminum foil.

Lithium-ion battery aluminum-plastic film

Lithium-ion battery aluminum-plastic film can be divided into three layers: the inner layer is adhesive layer, the use of polyethylene or polypropylene material, achieving the sealing effect. The intermediate layer is an aluminum foil, which prevents penetration of the outside water of the battery while preventing the internal electrolyte from leaking. The outer layer is the protective layer, using high melting point of polyester or nylon material, which has a strong mechanical properties to prevent external damage to the battery, playing the role of protecting the battery.

As a liquid soft packaging lithium-ion battery shell, the aluminum-plastic composite film is no longer just a simple packaging of the battery, but also an indispensable and important part of liquid soft packaging lithium-ion battery.

The aluminum foil for lithium-ion battery

The aluminum foil of aluminum-plastic film intermediate layer is mainly 1050 aluminum foil, 1060 aluminum foil, 1235 aluminum foil etc., and the temper is O, H14, H24, H22, H18. Mingtai aluminum produces aluminum foil special for lithium battery, having cooperative relations with many companies.
