In above-described technical solution of the present invention, the thickness that is in the nickel coating of lug lamellar body one side (front or reverse side) can be the 0.5-3.0 micron.
In above-described technical solution of the present invention, the lower end of set nickel coating does not exceed the lug lamellar body of lug PP film lower end institute corresponding position.
The invention also discloses production method a kind of as described polymer of above technical scheme or liquid flexible packing lithium ion electric core usefulness anode ear, be characterized in, it is base material with the aluminium foil, adopt chemical plating or electric plating method to carry out in an end of aluminium foil all or topical nickel galvanization, form packaging type or tow sides formula or one plane type nickel coating in an end of aluminium foil; Then the aluminium foil after the nickel plating is cut into aluminum strip by the specification of lug, aluminum strip after will cutting again carries out integral body or local corrosion-resistance treatment (can be undertaken by disclosed any corrosion-resistance treatment technology in the prior art), at last lug PP film is located on the aluminum strip, promptly with the compound mode of hot pressing.
The invention also discloses another kind as the described polymer of above technical scheme or liquid flexible packing lithium ion electric core production method with anode ear, be characterized in, it is base material with the aluminium foil, aluminium foil is cut into aluminum strip by the specification of lug, it is compound with the hot pressing of lug PP film that aluminum strip is carried out corrosion-resistance treatment (can be undertaken by disclosed any corrosion-resistance treatment technology in the prior art) back, adopt chemical plating or electric plating method to carry out in an end of aluminium foil all or topical nickel galvanization one end of aluminum strip at last, end at aluminium foil forms packaging type or tow sides formula or one plane type nickel coating, promptly.
In above-described production method of the present invention, the width of described aluminum strip can be selected on demand, is generally the 1-60 millimeter.
Compared with prior art, polymer Li-ion electricity core (or flexible packing lithium ion electric core) lug of the present invention is a kind of nickel anode ear of exempting to change, and it is simple in structure, and nickel coating can be operated by the mode of chemical plating or plating.Polymer of the present invention or liquid flexible packing lithium ion electric core can be directly with anode ear and protective circuit weld; reduced the bending number of times of lug; make lug be not easy to fracture; can not cause the problem of sealing-off (being that solder joint comes off) yet; improve the quality of product effectively, improved the rate that manufactures a finished product, prolonged the useful life of product; and the operation that one aluminium pole ears that has reduced electric core production firm changes nickel has shortened the production cycle.
