Abstract
The invention relates to a multifunctional aluminum film applied to a polymer lithium ion battery. The aluminum film sequentially comprises a functional layer, a nylon and polypropylene co-extrusion layer, a first adhesive layer, an aluminum foil layer, a second adhesive layer and a non-tape-casting polypropylene layer from outside to inside. The outer layer of nylon is coated by a layer of multifunctional paint so that abrasion resistance of the nylon layer can be effectively improved; by means of the characteristic of a nylon and polypropylene co-extrusion product, the barrier property of the nylon layer and adhesion strength of the inner layer can be effectively improved, layering resistance of the aluminum film is improved, and the aluminum film is an outer package aluminum film material capable of being applied to the polymer lithium ion battery.
Description
Technical field
The present invention relates to battery packaging material field, particularly to a kind of polymer Li-ion battery application Mobyneb aluminum
Plastic film.
Background technology
Polymer battery have than liquid lithium ionic cell more weight amount, voltage is high, capacity is big, the life-span is long, self discharge is low,
More advantage such as memory-less effect and safety, in recent years along with it is in the extensive application of the 3C products such as iPhone, iPad, Ultrabook, in addition the exploitation of lithium ion battery electric automobile, the application of polymer Li-ion battery the most quickly increases, owing to aluminum plastic film is the important housing material of lithium ion battery flexible package, the most also drive the quick growth of aluminum plastic film demand.
The fluorinated materials such as hexafluorophosphoric acid aluminum are had due to the electrolyte in lithium ion battery, these fluorochemicals have the strongest sensitivity to water, electrolyte is met water and is readily generated severe corrosive Fluohydric acid. and other gases, the heat-sealing of aluminum plastic film and material will be caused corrosion by it, have a strong impact on cycle-index and the service life of battery, causing battery rapid failure, therefore aluminum plastic film need to have the barrier property of excellence, intercepts the factor destructions to electrolyte such as the steam of external environment, oxygen.Meanwhile, the aluminum plastic film outer layer of battery needs resist in cell processing course to fall the destruction caused, and needs aluminum plastic film outer layer to have the anti-wear performance of excellence.It addition, the heat sealability of aluminum plastic film and ductility and chemical stability are the most extremely important to the prolonged application of battery.How improving the anti-wear performance of aluminum plastic film, barrier property and other correlated performances to promoting polymer Li-ion battery quality is the most crucial matter of science and technology.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides a kind of polymer Li-ion battery application Mobyneb aluminum plastic film, and this aluminum plastic film has the multiple protection battery functi ons such as barrier property and the anti-wear performance of excellence.
The technical scheme is that a kind of polymer Li-ion battery application Mobyneb aluminum plastic film.This aluminum plastic film includes functionalization layer, nylon and polypropylene coextruded layer, adhesive layer, aluminium foil layer, adhesive layer, non-cast polypropylene layer, and it is followed successively by functionalization layer, nylon and polypropylene coextruded layer, adhesive layer, aluminium foil layer, adhesive layer, non-cast polypropylene layer from outside to inside.
The preparation method of a kind of polymer Li-ion battery application Mobyneb aluminum plastic film, comprises the steps: the outer layer coating functions coating of alkene coextruded layer, dries, obtains aluminum plastic film.1) nylon forms co-extrusion thing with polypropylene fusion co-extrusion；
2) co-extrusion thing and aluminium foil, non-cast polypropylene material are carried out being laminated by adhesive, bond, are dried, finished film at the beginning of obtaining；3) at nylon and the outer layer coating functions coating of polypropylene coextruded layer of first finished film, dry, obtain aluminum plastic film.
After using technique scheme, beneficial effects of the present invention: first, by multi-functional nylon outer layer coating one layer
Coating, can be effectively improved the wearability of nylon layer；Secondly, nylon and polypropylene are co-extrusion thing, can be effectively improved nylon layer barrier property and with the adhesion strength of internal layer, improve aluminum plastic film resist delamination ability.
