Description
Technical field
The invention belongs to lithium battery manufacturing technology fields, are related to a kind of metal-coated membrane applied to lithium battery.
Background technique
The packaging of lithium battery is gradually changed to soft aluminizer outer packing from hard steel shell, the aluminum hull of low and middle-end, using plating
After aluminium film, realize that lithium battery aluminum amount is few, the aluminizer on both sides is separated by plastic foil, causes resistance to increase, the conducting energy of electric current
Power decline.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, propose a kind of applied to the gold-plated of lithium battery
Belong to film, be equipped with micro-hole, micro-hole is full of when metal-coated membrane, so that the two panels metal film separated by PET film can be with intercommunication conduction.
Object of the invention can be realized by the following technical scheme: a kind of metal-coated membrane applied to lithium battery, special
Sign is, including is located at middle layer, and middle layer both sides are surface-treated layer, and the outer surface of surface-treated layer is coated with metal layer, institute
Stating middle layer is PET film, and surface-treated layer is rough rough layer or the high adhesive layer of attachment fastness, the metal layer are
Aluminium film or copper film are covered with micro-hole in the middle layer.
Further, the rough layer is sandblasting layer.
Further, the adhesive layer is using sided corona treatment, electric spark processing, plasma treatment, plating NI processing, plating
The one or more such as ALO processing, chemical treatment coating, NAOH immersion.Adhesive layer increases between aluminizer, copper plating film and PET film
Attachment fastness.
Further, the aluminium film is with a thickness of 0.3-2.5 microns；
Further, the copper film thickness is 0.2-1.2 microns；
Further, the adhesive layer is with a thickness of 0.005-0.05 microns.
Further, the diameter of the micro-hole is 10-100 microns, 0.5-1 millimeters of spacing.
Compared with prior art, the metal-coated membrane that should be used for lithium battery has the advantage that
1. being provided with micro-hole, the conducting effect of enhancing tow sides metal layer electric current reduces resistance；
2. being provided with micro-hole, enhance the binding strength of tow sides metal layer and film；
3. aluminium film, copper film tensile strength is high, ductility is good, density is small, the weight of lithium battery is reduced；
4. middle layer is PET film, realize that lithium battery aluminum amount is few, final products safety is promoted；
5. subsequent can increase types of functionality substance on metal film base material, increase application range.
