Description

A kind of anode ear of polymer Li-ion battery
Technical field
The utility model relates to technical field of lithium batteries, particularly relates to a kind of anode ear of polymer Li-ion battery.
Background technology
When using aluminum plastic film material as the lithium ion battery packed, the lug that all will to use with flexible glue be joint filling material is as the conductive current collector of battery core, and the welding performance of this kind of lug current-carrying part metal material directly has influence on the production efficiency of finished product lithium ion battery and produces excellent rate.When producing or using lithium ion battery, the battery core of lithium ion battery is all needed to weld with protective circuit plate or electric wire, by lithium ion battery just, negative pole lug welding is on protective circuit plate or electric wire, the anode ear of current lithium ion battery generally all adopts aluminum material to make, because aluminum material is poor with metallic tin affinity, be not easy directly to carry out soldering on the anode ear of aluminum, so lithium ion battery needs to weld one section of nickel strap or aluminium nickel composite band (namely turning nickel) by Laser Welding or supersonic welding in use on anode ear bared end make easily soldering between itself and protective circuit plate or electric wire, but turn nickel troublesome poeration, process is complicated, turn nickel inefficiency, have impact on the production efficiency that anode ear turns nickel speed and lithium ion battery producer greatly, in addition, turn very easily sealing-off and the frangibility of the anode ear after nickel, thus the normal service life of the impact rate of finished products of producing and product.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art; there is provided a kind of anode ear of polymer Li-ion battery, one end of its anode ear, without the need to welding nickel strap or copper strips again, just can directly be welded with route protection plate; not only save time, can also reduce costs.
The utility model realizes like this, a kind of anode ear of polymer Li-ion battery, comprise aluminium nickel composite band and be arranged on the insulation colloid in described aluminium nickel composite band, described aluminium nickel composite band comprises an aluminium lamination and and is arranged on nickel dam on described aluminium lamination one surface, and the end on described another surface of aluminium lamination is provided with a nickel sheet for welding with wiring board.
Further, described insulation colloid is coated with described aluminium nickel composite band and described insulation colloid extends the both sides of described aluminium nickel composite band respectively along the both sides of described aluminium nickel composite band Width.
Further, the width of described nickel sheet is identical with the width of described aluminium lamination.
Further, the thickness of described nickel sheet is identical with the thickness of described nickel dam.
Further, the upper surface of described nickel sheet is formed with multiple hole shape structure.
Further, the end that the lower surface of described nickel dam welds with described wiring board is formed with multiple hole shape structure.
Further, the thickness of described aluminium nickel composite band is 0.1mm, and the thickness of described aluminium lamination is 0.05mm, and the thickness of described nickel dam is 0.05mm, and the thickness of described nickel sheet is 0.05mm.
