Abstract
The invention discloses an anti-puncture aluminum plastic film for encapsulating a lithium battery. The aluminum plastic film comprises an outer film layer, an anti-puncture layer, an inner film layer, an aluminum foil layer and a heat-seal layer which are sequentially arranged from outside to inside, wherein the outer film layer, the anti-puncture layer, the inner film layer, the aluminum foil layer and the heat-seal layer are bonded and compounded by glue; the outer film layer is a polyfluorinared ethylene propylene film, the inner film layer is a polyester film, the anti-puncture layer is formed by interweaving warps and wefts, the warps are aramid yarns, and the wefts are nylon yarns. Therefore, the anti-puncture aluminum plastic film is simple and reasonable in structure, and has better puncture resistance.
Description
Technical field
The present invention relates to encapsulating material technical field, particularly relate to a kind of puncture resistant lithium battery encapsulation aluminum plastic film.
Background technology
Gas is the most easily discharged for current rigid pack lithium battery, pressure increase causes explosion issues, start that novel flexible packing material-aluminum plastic film occurs on the market, soft package lithium battery structurally uses laminated aluminum film, split occurring soft package lithium battery in the case of potential safety hazard the most only air-blowing, and can explode unlike box hat aluminum hull battery core.Existing this aluminum plastic film puncture resistance is not good enough.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of puncture resistant lithium battery encapsulation aluminum plastic film, simple and reasonable, has preferable puncture resistance.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of puncture resistant lithium battery encapsulation 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, described theca externa, puncture resistant layer, theca interna, compound by glue bonding between aluminium foil layer and hot sealing layer, described theca externa is polyfluorinated ethylene membrane, described theca interna is mylar, described puncture resistant layer is interwoven by warp and parallel, described warp is aramid yarn, and described parallel is nylon yarn.
In a preferred embodiment of the present invention, described warp thread is merged twisting by three aramid fibers and forms.
In a preferred embodiment of the present invention, the fineness of described aramid fiber is 3 ~ 5D.
In a preferred embodiment of the present invention, described weft yarn is merged twisting by three nylon fibers and forms.
In a preferred embodiment of the present invention, the fineness of described nylon fiber is 3 ~ 5D.
The invention has the beneficial effects as follows: puncture resistant lithium battery encapsulation aluminum plastic film of the present invention, simple and reasonable, there is preferable puncture resistance.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of puncture resistant lithium battery encapsulation aluminum plastic film one preferred embodiment of the present invention.
In accompanying drawing, the labelling of each parts is as follows: 1, theca externa, and 2, puncture resistant layer, 3, theca interna, 4, aluminium foil layer, 5, hot sealing layer.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of puncture resistant lithium battery encapsulation aluminum plastic film, including: the theca externa 1 set gradually from outside to inside, puncture resistant layer 2, theca interna 3, aluminium foil layer 4 and hot sealing layer 5, described theca externa, puncture resistant layer, theca interna, it is combined by glue bonding between aluminium foil layer and hot sealing layer, described theca externa is polyfluorinated ethylene membrane, described theca interna is mylar, described puncture resistant layer is interwoven by warp and parallel, described warp is aramid yarn, described parallel is nylon yarn, aramid yarn and nylon yarn are respectively provided with higher Resisting fractre intensity, the puncture resistant layer of braiding, intensity is higher, it is difficult to be the worse for wear.
Preferably, described warp thread is merged twisting by three aramid fibers and forms, and the fineness of described aramid fiber is 3 ~ 5D, and intensity is high, not easy fracture.
Preferably, described weft yarn is merged twisting by three nylon fibers and forms, and the fineness of described nylon fiber is 3 ~ 5D, and intensity is high, not easy fracture.
The invention has the beneficial effects as follows: puncture resistant lithium battery encapsulation aluminum plastic film of the present invention, simple and reasonable, there is preferable puncture resistance.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in the scope of patent protection of the present invention.
