Outer packing.Plastic-aluminum packaging film has flexibility as the outer packaging bag of lithium battery, can discharge lithium battery and anticipate in use
The supercharging that outer release gas generates, prevents battery explosion.The membrane material usually have the aluminium foil of high water vapor rejection with good resistance to
Chemically, heat sealability and flexible plastic foil are combined.
Lithium battery encapsulation is used for cell package with aluminum plastic film, overcomes the peace that the battery of hard material encapsulation for a long time is brought
Full hidden danger：Battery explosion caused by inflatable.All the time, lithium battery only focuses on the cold of material with aluminum-plastic membrane used for packaging research and development producer and adds
Work performance does not pay attention to the perishable drawback of aluminum plastic film outer layer, causes the electricity accidentally dripped during noting electrolyte
It solves liquid to corrode aluminum plastic film outer layer, reduces the barrier property and dielectric coefficient of battery entirety, and influence the beauty of battery, together
When, more likely there is bulge or explodes in battery under the shock by external force.
Utility model content
In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of with table
The aluminum plastic film of the corrosion-resistant function of layer can effectively solve existing aluminum plastic film in the presence of easy by electrolytic corrosion and easy explosion
Problem.
To achieve the above object, the utility model is using following technical solution：
A kind of aluminum plastic film with the corrosion-resistant function in surface layer, includes black plastic film matrix, the first adhesive linkage, aluminium foil
Layer, the second adhesive linkage, polyethylene low ratio foamed film and polytetrafluoroethylene film layer；The black plastic film substrate layer and laminate aluminium foil
It is located at together, the centre of the aluminium foil layer and black plastic film matrix is coated with the first adhesive linkage, and the lower surface of the aluminium foil layer applies
Equipped with the second adhesive linkage, lower surface and the polyethylene low ratio foamed film of second adhesive linkage are bonded together, and the polytetrafluoroethylene (PTFE) is thin
Film layer is folded to be located on the lower surface of polyethylene low ratio foamed film.
As a preferred embodiment：The thickness of the black plastic film substrate layer is 10-30 μm.
As a preferred embodiment：First adhesive linkage and the second adhesive linkage are polyurethane glue-line, and thickness is 3 μ

The utility model has clear advantage and advantageous effect compared with prior art, specifically, by above-mentioned technology
Known to scheme：
By using polytetrafluoroethylene film in outer layer, during electrolyte is injected in encapsulation, aluminum plastic film surprisingly contacts drop
Be not in be set additionally, due to the Reasonable Parameters of aluminium foil and polyethylene low ratio foamed film the phenomenon that being corroded after the electrolyte fallen
It sets, enhances the slipping and explosion-proof performance of aluminum plastic film.
More clearly to illustrate the structure feature and effect of the utility model, come below in conjunction with the accompanying drawings with specific embodiment pair
The utility model is described in detail.
