Abstract
This utility model relates to the glued membrane of lithium battery pole ear, and its cross section is layer structure, and its cross section structure includes the new function bonding resin layer of internal layer, is close to HOPP layer on the downside of new function bonding resin layer；It is provided with co-polypropylene layer at homo-polypropylene layer outer layer.This utility model homo-polypropylene layer adds in HOPP ceramics, the insulating properties of glued membrane can be greatly improved, and also be able to improve the heat resistance of glued membrane, when preventing battery from using discharge superheat, cause glued membrane to melt, it is provided that battery safety in utilization.
Description
Technical field
This utility model relates to the clad technical field of lithium battery pole ear, in particular to the glued membrane that lithium battery pole ear carries out sealed insulation.
Background technology
Lug, is parts of lithium ion polymer battery product.The battery of mobile phone such as used in our life, Bluetooth battery, Notebook Battery etc. is required for using lug.Battery is a point both positive and negative polarity, and lug is exactly the metallic conductor extracted by both positive and negative polarity from battery core, and the popular ear saying battery positive and negative polarities is the contact point when carrying out discharge and recharge.This contact point is not that copper sheet of the battery appearance that we have seen that, but a kind of connection of inside battery.Lug is divided into three kinds of materials, and the positive pole of battery uses aluminum (Al) material, and negative pole uses nickel (Ni) material, and negative pole also has copper nickel plating (Ni Cu) material, and they are all to be composited by film and metal tape two parts.Film is the part of insulation on lug, prevents from being short-circuited between metal tape and aluminum plastic film when its effect is cell package, and is bonded together is prevented leakage by heating (about 140 DEG C) and aluminum plastic film hot-melting sealed when encapsulating.One lug is clipped in the middle metal tape by two panels film.
The film of existing market lug cladding has black glue, white glue and three kinds of monolayer glue.Conventional black film is three-decker: melanin, fusing point 66 DEG C；PE, fusing point 105 DEG C；PP, fusing point 137 DEG C.Film to lug cladding currently on the market, its insulating properties is poor, and thermostability is poor, is thus likely to cause battery short circuit, causes electric leakage, even causes the blast of whole battery, causes security incident.
Utility model content
The purpose of this utility model is to overcome weak point of the prior art, it is provided that the glued membrane of the lithium battery pole ear of a kind of thermostability.
For achieving the above object, this utility model adopts the following technical scheme that:
The glued membrane of lithium battery pole ear, its cross section is layer structure, and its cross section structure includes the new function bonding resin layer of internal layer, is close to HOPP layer on the downside of new function bonding resin layer；It is provided with co-polypropylene layer at homo-polypropylene layer outer layer.
Described co-polypropylene layer thickness is 5-15 micron, and the thickness of homo-polypropylene layer uses 50-120 micron, and novel adhesion resin (AD) thickness is 5-15 micron.
The beneficial effects of the utility model are: add ceramics in this utility model homo-polypropylene layer in HOPP, the insulating properties of glued membrane can be greatly improved, and also be able to improve the heat resistance of glued membrane, when preventing battery from using discharge superheat, glued membrane is caused to melt, it is provided that battery safety in utilization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with each specific embodiment and Figure of description, the utility model is described in further detail:
The glued membrane of the lithium battery pole ear of thermostability disclosed in this utility model, its cross section is layer structure, its cross section structure includes the new function bonding resin layer 1 of internal layer, and heat resistance can reach 100 ° of C, is close to homo-polypropylene layer 2 on the downside of new function bonding resin layer 1；It is provided with co-polypropylene layer 3 at homo-polypropylene layer 2 outer layer.
Described co-polypropylene layer 3 thickness is 5-15 micron, and the thickness of homo-polypropylene layer 2 uses 50-120 micron, and novel adhesion resin (AD) thickness is 5-15 micron.The glued membrane of this thickness, has more preferable ruggedness, has preferably thermostability and insulating properties.
In a word, this utility model homo-polypropylene layer 2 can be greatly improved the insulating properties of glued membrane, and also is able to improve the heat resistance of glued membrane, when preventing battery from using discharge superheat, causes glued membrane to melt, it is provided that battery safety in utilization.
The above is only to preferred embodiment of the present utility model; not scope of the present utility model is defined; therefore on the premise of without departing from this utility model design spirit; the equivalence that structure described in the utility model, feature and principle are done by this area ordinary skill technical staff changes or decoration, all should fall in the protection domain that this utility model is applied for a patent.
Claims (2)
1. the glued membrane of lithium battery pole ear, its cross section is layer structure, it is characterised in that: its cross section structure includes the new function bonding resin layer of internal layer, is close to homo-polypropylene layer on the downside of new function bonding resin layer；It is provided with co-polypropylene layer at homo-polypropylene layer outer layer.
The glued membrane of lithium battery pole ear the most according to claim 1, it is characterised in that: described co-polypropylene layer thickness is 5-15 micron, and the thickness of homo-polypropylene layer uses 50-120 micron, and novel adhesion resin (AD) thickness is 5-15 micron.
