Technical field
A kind of relevant soft package lithium battery encapsulating material of the present invention, particularly it is a kind of have high degree adherence, be not easy to burst,
High temperature resistant, erosion-resisting ultrathin aluminum plastic film package material, make soft package lithium battery volume thinner and can extend service life, lifting
The efficiency of lithium battery.
Background technology
With the evolution and development of mobile communication equipment, the trend of intelligent mobile phone towards thin type strides forward at present, therefore,
Soft Roll poly-lithium battery can also turn at present on the market by thin slice positive and negative electrode connecting communication equipment to provide power supply
Battery used in main flow communication apparatus, and iPhone, iPad and other communication apparatus are widely used in, it is larger with displacement thickness
Ni-MH battery (Ni-MH), iron lithium phosphate (LiFePO4), three elements (lithium cobalt nickel-based battery Li (NiCo) O2), lithium cobalt
(LiCoO2), lithium manganese (LiMno2) battery；Therefore, to meet the mobile communication equipment of thin type, lithium battery encapsulation equipment vendors
The program researched and developed and tested for the aluminum plastic film with encapsulation function.
However, often there is the situation that expansion is damaged in lithium battery at present, due to abnormal chemical inside poly-lithium battery
During generated reactive gas, after outer packing gassy, battery bulging makes soft-package battery that swelling state be presented, what is more, will be outer
Packaging struts explosion, battery is formed explosive event and injures user；Lithium battery expansion reason is caused at present as follows：Envelope
Fill bad；Pocket surface fractures；Angle position is damaged；Battery interior moisture content is exceeded；It is abnormal to be melted into flow mistake；SEI films are not
It is stable；Excessive charge and discharge；External short circuit；Internal short-circuit；Caused by the reasons such as corrosion and vacuum suction are abnormal, trigger lithium battery
Expansion causes running gear to damage.
Soft package lithium battery often because top sealing, side seal and vacuum degassing, formed three bandings fill it is bad caused by,
Encapsulate the bad moisture in air that easily causes to enter inside battery, trigger electrolyte decomposition to produce gas, or due to encapsulating sheet
Piece is damaged, angle position is damaged or above-mentioned other factors cause soft package lithium battery formation expansion even to burst, and causes user injured
Or battery is damaged, at present polymer lithium-ion battery flexible packing material be by aluminium foil, a variety of plastic cement and a variety of adhesives (including
Binding resin) composite soft packaging material that is formed, because interior packing has tool mobility, permeability, corrosivity, deliquescent
Electrolyte, therefore, soft package lithium battery outer enclosure become the problem extremely paid attention to for relevant manufactures.
At present common aluminum plastic film be largely with an outer layer, one first solid, an intermediate layer, one second solid and
One hot sealing layer, the first solid combine outer layer inner face and an intermediate layer, and the second solid is by among hot sealing layer inner face and one
Layer makees the structure that combines so that ultrathin aluminum plastic film in packaging can frivolous facility, but on covering property and explosion-proof equipment
Damage is easily caused, causes the damage of battery；Therefore, just there is related dealer to research and develop a kind of aluminum plastic film, its structure include an outer layer,
One first following layer, one first priming coat, an intermediate layer, one second priming coat, one second following layer, a hot sealing layer, its is main
Purpose is in that by one first priming coat and one second priming coat, is functional processing layer, has and hinders wet, choke structure,
First priming coat is to be modified acrylic (PMMA), and polyvinyl alcohol, conditioning agent, nano silicon oxide, coupling agent, tackifier and water group
Into, conditioning agent is the mixture of methanol and ethanol, and coupling agent is made up of amino silane, alcohol metatitanic acid fat, alcohol alkoxy titanates,
Tackifier are polyethylene；Mainly with functional processing layer, handle inside multilayer composite film, as protection intermediate layer and barrier
Pattern handling, for improve the outer layer, intermediate layer and seal interlayer viscosity, be that coupling agent and increasing are added in priming coat
Stick ... etc., but the thickness of aluminum plastic film is also therefore added, therefore, stickiness intensity and reduction thickness are become for related dealer
The problem studied intensively.
The content of the invention
The conventional aluminum plastic film encapsulating material of soft package lithium battery just needs to have light, thin, high temperature resistant, anticorrosive, anti-puncture ...
Correlation properties, therefore, aluminum plastic film common at present are generally multi-functional comprising an external protection, a middle aluminium foil layer and an internal layer
Layer is formed, and the external protection is mainly that good protective effect, in-between aluminium foil layer are played to intermediate layer to oxygen or other streams
Body should can produce absolute iris action, and making gas or other fluid percent of pass, the internal layer Multifunctional layered must then have close to zero
For good chemical stability, good puncture resistant properties, high temperature resistant and seal not short-circuit and guarantee sealing-strength, this crime
A person of good sense's just each continuous research and development of layer for more than, develop finally a kind of extremely light, very thin, high temperature resistant, it is anticorrosive, anti-puncture and
The extremely strong ultrathin aluminum plastic film encapsulating structure of sticky limit.
A kind of relevant ultrathin aluminum plastic film of the present invention, sequentially include a top layer, a P process layers, an adhesion coating, at an OC
Manage layer, an aluminium foil layer, an OC process layers, an adhesion coating, a P process layers and a hot sealing layer；Wherein, the top layer is less than 15 μm,
Formed with polyamide；The P process layers, between the top layer, adhesion interlayer and hot sealing layer, adhesion interlayer, include acetic acid second
Ester, polyimides and hardener component, the top layer, adhesion interlayer and hot sealing layer, adhesion coating is set to possess the last one adhesion strength；Adhesion
Layer, content mixing addition is waited comprising optics anacidity glue, curing agent, assistants and additives ..., intermediate layer is aluminium foil layer, and thickness is situated between
Between 20 μm~25 μm, there is the architectural characteristic of isolation light, air and moisture, an OC is provided with aluminium foil layer and adhesion interlayer
Process layer, the OC process layers include silica and cadmium, the adhesive force between adhesion coating and aluminium foil layer can be improved, in adhesion coating
Part simplify technique, coupling agent and tackifier are removed, and be packaged using the mode of double sandwich, form it into and one surpass
The plastic-aluminum membrane structure thin, stickiness is extremely strong.
