Description
Technical field
The present invention relates to encapsulating material technical fields, more particularly to a kind of puncture resistant lithium battery encapsulation aluminum plastic film.
Background technology
Gas is easily discharged in use for current rigid pack lithium battery, and pressure increase leads to explosion issues, city
Start novel flexible packing material-aluminum plastic film occur on face, soft package lithium battery uses laminated aluminum film in structure, and safety is occurring
Soft package lithium battery at most only understands air-blowing and splits in the case of hidden danger, can explode like that rather than box hat aluminum hull battery core.It is existing
This aluminum plastic film puncture resistance it is not good enough.
Invention content
The invention mainly solves the technical problem of providing a kind of puncture resistant lithium battery encapsulation aluminum plastic film, conjunctions simple in structure
Reason has preferable puncture resistance.
In order to solve the above technical problems, one aspect of the present invention is：A kind of puncture resistant lithium battery envelope is provided
Dress aluminum plastic film, including：Theca externa, puncture resistant layer, theca interna, aluminium foil layer and the hot sealing layer set gradually from outside to inside, it is described
Bonded by glue between theca externa, puncture resistant layer, theca interna, aluminium foil layer and hot sealing layer it is compound, the theca externa be poly- perfluor
Second Polypropylene film, the theca interna are polyester film, and the puncture resistant layer is interwoven by warp and weft, and the warp is virtue
Synthetic fibre yarn, the weft are nylon yarn.
In a preferred embodiment of the present invention, the warp thread is twisted by three aramid fiber merging.
In a preferred embodiment of the present invention, the fineness of the aramid fiber is 3 ~ 5D.
In a preferred embodiment of the present invention, the weft yarn is twisted by three nylon fiber merging.
In a preferred embodiment of the present invention, the fineness of the nylon fiber is 3 ~ 5D.
The beneficial effects of the invention are as follows：Puncture resistant lithium battery encapsulation aluminum plastic film of the present invention, it is simple and reasonable, have compared with
Good puncture resistance.
Description of the drawings
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, wherein：

The label of each component is as follows in attached drawing：1, theca externa, 2, puncture resistant layer, 3, theca interna, 4, aluminium foil layer, 5, heat-sealing
Layer.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
All other embodiment that technical staff is obtained without making creative work belongs to the model that the present invention protects
It encloses.
Referring to Fig. 1, the embodiment of the present invention includes：
A kind of puncture resistant lithium battery encapsulation aluminum plastic film, including：Theca externa 1, the puncture resistant layer set gradually from outside to inside
2, theca interna 3, aluminium foil layer 4 and hot sealing layer 5 pass through between the theca externa, puncture resistant layer, theca interna, aluminium foil layer and hot sealing layer
Glue bond it is compound, the theca externa be polyfluorinated ethylene membrane, the theca interna be polyester film, the puncture resistant layer by
Warp and weft are interwoven, and the warp is aramid yarn, and the weft is nylon yarn, and aramid yarn and nylon yarn are equal
With higher Resisting fractre intensity, puncture resistant layer made of braiding, intensity is higher, is not easy to be the worse for wear.
Preferably, the warp thread is twisted by three aramid fiber merging, and the fineness of the aramid fiber is 3 ~ 5D, by force
Degree is high, not easy to break.
Preferably, the weft yarn is twisted by three nylon fiber merging, and the fineness of the nylon fiber is 3 ~ 5D, by force
Degree is high, not easy to break.
The beneficial effects of the invention are as follows：Puncture resistant lithium battery encapsulation aluminum plastic film of the present invention, it is simple and reasonable, have compared with
Good puncture resistance.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
