Abstract
This utility model provides a kind of copper plastic film of improvement, including the hot sealing layer of the protective layer, middle layers of copper and internal layer of outer layer, and the two sides of the layers of copper is electroplated or is covered with aluminium lamination, and the aluminium lamination of the layers of copper both sides is combined with protective layer and hot sealing layer respectively by binding agent.Intermediate layer of the present utility model is layers of copper, and using the aluminum plastic film of aluminium lamination, structural strength is higher, is less prone to the damaged situation of encapsulation；And the two sides of the layers of copper is electroplated or is covered with aluminium lamination; as passivation layer is easily formed on aluminium lamination; so the layers of copper of this copper plastic film just can be firm with protective layer and hot sealing layer bonding well by aluminium lamination; so that layers of copper is difficult exposure in the electrolytic solution, it is ensured that the security performance of the lithium battery for manufacturing.
Description
Technical field
This utility model is related to lithium battery production technical field, the copper plastic film of more particularly to a kind of improvement.
Background technology
Lithium ion battery has had more than 20 to application Zi research and development so far as a most widely used rechargeable battery
Year history.As other batteries, lithium ion battery is also by positive pole, negative pole, barrier film, electrolyte, collector and outer package
Housing is constituted.The chemical property of lithium ion battery effective ingredient is all very active, is placed in air the even blast that is easy to catch fire,
Thus the packaging shell of lithium ion battery should have certain corrosion resistance and very excellent barrier, the packaging commonly used at present
Mainly there are box hat, aluminum hull and high molecular aluminium plastic film.Battery is packed using aluminum-plastic composite membrane, have the advantages that it is lightweight,
The specific energy of battery can significantly be lifted.And laminated aluminum film film has very big flexibility, can effectively reduce electricity
Pond it is intrinsic pressure, be not in explosion danger.
The ductility of metal current aluminum is good not as Cu, and after the thickness of aluminium foil is thinning, deflection is not enough.The aluminum plastic film thing of making
Rationality can be not so good as the copper plastic film of condition of equivalent thickness.For the problems referred to above, there is part businessman to propose a kind of copper plastic film, but this copper is moulded
The surface of the layers of copper in film is not easily formed passivation layer, causes all bonding and layers of copper and hot sealing layer between layers of copper and protective layer
It is insecure, easily come off, electrolyte is easily contacted with copper, a series of problems, such as so as to cause battery short circuit, battery flatulence, sternly
Fire explosion can more be produced during weight, irremediable security incident is easily caused.
Utility model content
Disappearance of this utility model for prior art presence, there is provided the copper plastic film of a kind of improvement, during which can make copper plastic film
Layers of copper and protective layer and hot sealing layer all it is bonding firmly, make electrolyte be difficult to contact with copper, it is ensured that the lithium battery for manufacturing
Security performance.
For achieving the above object, this utility model is using such as purgation technical scheme：
A kind of copper plastic film of improvement, including the hot sealing layer of the protective layer, middle layers of copper and internal layer of outer layer, the layers of copper
Two sides is electroplated or is covered with aluminium lamination, and the aluminium lamination of the layers of copper both sides is combined with protective layer and hot sealing layer respectively by binding agent.
Used as a kind of preferred version, the thickness of the aluminium lamination is 2-5 μm.
Used as a kind of preferred version, the surface of the aluminium lamination is provided with passivation layer.
Used as a kind of preferred version, the protective layer is PA layers or pet layer.
Used as a kind of preferred version, the thickness of the protective layer is 5-50 μm.
Used as a kind of preferred version, the hot sealing layer is CPP layers.
Used as a kind of preferred version, the thickness of the hot sealing layer is 10-100 μm.
Used as a kind of preferred version, described adhesive is maleated polypropylene.
This utility model compared with prior art, with advantages below and advantage, specifically, the intermediate layer of this copper plastic film
For layers of copper, the two sides of the layers of copper is electroplated or is covered with aluminium lamination, forms passivation layer due to easy on aluminium lamination, so this copper
The layers of copper of plastic film just can be firm with protective layer and hot sealing layer bonding well by aluminium lamination, so that layers of copper is difficult to be exposed to electrolysis
In liquid, it is ensured that the security performance of the lithium battery for manufacturing；On the other hand, metallic copper compares metallic aluminium, and intensity is higher, makes
Copper plastic film encapsulate when be less prone to breakage situation.
More clearly to illustrate architectural feature of the present utility model, technological means and its specific purposes for being reached and work(
Can, below in conjunction with the accompanying drawings with specific embodiment being described in further detail to this utility model：
Description of the drawings
Fig. 1 is the assembly structure diagram of the embodiment of this utility model.
Accompanying drawing identifier declaration：
1- protective layers, 2- layers of copper, 3- hot sealing layers, 4- binding agents, 5- aluminium laminations, 6- passivation layers.
Specific embodiment
As shown in figure 1, a kind of copper plastic film of improvement, including the heat-sealing of the protective layer 1, middle layers of copper 2 and internal layer of outer layer
Layer 3, the plating of the two sides of the layers of copper 2 or is covered with aluminium lamination 5, the aluminium lamination 5 of 2 both sides of the layers of copper by binding agent 4 respectively with guarantor
Sheath 1 and hot sealing layer 3 are combined.The thickness of the aluminium lamination 5 is 2-5 μm.The surface of the aluminium lamination 5 is provided with passivation layer.The protection
Layer 1 is PA layers or pet layer.The thickness of the protective layer 1 is 5-50 μm.The hot sealing layer 3 is CPP layers.The thickness of the hot sealing layer 3
Spend for 10-100 μm.Described adhesive 4 is maleated polypropylene.
The above, is only preferred embodiment of the present utility model, not to limit this utility model, thus it is every
Any modification, equivalent substitution and improvements actually made to above example according to technology of the present utility model etc., still fall within this
In the range of utility model technical scheme.
