Description
Technical field
The utility model relates to lithium battery packing technique field, specially a kind of lithium battery composite packing film.
Background technique
It by lithium metal or lithium alloy is negative electrode material, using the battery of non-aqueous electrolytic solution that lithium battery, which is a kind of,.Due to
The chemical characteristic of lithium metal is very active, so that the processing of lithium metal, preservation, use, very high to environmental requirement.So lithium
Battery is not applied for a long time.With the development of science and technology, present lithium battery has become mainstream.
Lithium battery uses aluminum-plastic composite membrane as packaging material at present, and the packaging material is wear-resisting, poor flame retardant properties, causes
There are major safety risks for lithium battery, therefore, it is necessary to improve.
Utility model content
The purpose of this utility model is to provide a kind of lithium battery composite packing films, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the utility model provides the following technical solutions: a kind of lithium battery composite packing film, including
Basement membrane, the basement membrane lower surface bonds anti-corrosion film layer, the anti-corrosion film layer lower surface bonds flame-retardant layer, the flame-retardant layer outside are set
Adhesive layer is set, the basement membrane upper surface is bonded enhancement layer, and wear-resisting film layer is arranged in the enhancement layer outer surface.
Preferably, the wear-resisting film layer includes composite glass fiber layer, strength glue-line, metallic diaphragm and PET film layer, described compound
Fiberglass layer is interwoven by glass composite yarn, and the composite glass fiber layer passes through strength glue-line bonded metal film layer, the PET film layer
It is arranged on the outside of metallic diaphragm.
Preferably, the anti-corrosion film layer uses furane resins composite anti-corrosive film.
Preferably, the enhancement layer uses BON biaxially oriented nylon film.
Preferably, the adhesive layer uses no-solvent polyurethane adhesive.
Preferably, the flame-retardant layer uses polyvinylidene chloride film layer.
Compared with prior art, the utility model has the beneficial effects that
(1) the utility model novel in structural design has the advantages that good resistance to compression, fire-retardant, high temperature resistant, wear-resisting, effectively
Protection lithium battery, no security risk.
(2) the utility model use wear-resisting film layer have excellent intensity and toughness, surface abrasion resistance with higher,
Extend the service life of composite membrane.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is the wear-resisting film layer cross-sectional view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole

Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of lithium battery composite packing film, including base
Film 1, the 1 lower surface bonds anti-corrosion film layer 2 of basement membrane, the 2 lower surface bonds flame-retardant layer 3 of anti-corrosion film layer, outside the flame-retardant layer 3
Adhesive layer 4 is arranged in side, and 1 upper surface of basement membrane is bonded enhancement layer 5, and wear-resisting film layer 6 is arranged in 5 outer surface of enhancement layer.
Wherein, anti-corrosion film layer 2 uses furane resins composite anti-corrosive film；Enhancement layer 5 uses BON biaxially oriented nylon film, tool
There is the characteristics of puncture-resistant, resistance to wrinkle；Adhesive layer 4 uses no-solvent polyurethane adhesive, and the adhesive layer adhesive property is good, but also
Have the advantages that fire-retardant；Flame-retardant layer 3 uses polyvinylidene chloride film layer.
In the utility model, wear-resisting film layer 6 includes composite glass fiber layer 7, strength glue-line 8, metallic diaphragm 9 and PET film layer 10,
The composite glass fiber layer 7 is interwoven by glass composite yarn, and the composite glass fiber layer 7 passes through 8 bonded metal film layer of strength glue-line
9, the setting of PET film layer 10 is in 9 outside of metallic diaphragm.The wear-resisting film layer that the utility model uses has excellent intensity and tough
Property, surface abrasion resistance with higher extends the service life of composite membrane.
In conclusion the utility model novel in structural design, with good resistance to compression, fire-retardant, high temperature resistant, wear-resisting excellent
Lithium battery, no security risk is effectively protected in point.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
