Description
Technical field
The utility model relates to the anode ear technical field of lithium battery, specially a kind of lithium battery anode ear.
Background technique
Tab is a kind of raw material of lithium ion polymer battery product, such as the battery of mobile phone used in our lives,
Bluetooth battery, Notebook Battery etc. require to use tab, and battery divides positive and negative anodes, and tab is exactly from battery core by positive and negative anodes
The metallic conductor extracted, the popular ear for saying battery positive and negative polarities are the contact points when carrying out charge and discharge, this connects
Contact be not we have seen that battery appearance that copper sheet, but a kind of connection of inside battery.
Existing lithium battery anode ear aluminium flake is more difficult when welding with nickel sheet, weld it is unstable and welding precision compared with
It is low, easily occur the phenomenon that tab fracture during aluminium-to-nickel.
Utility model content
The purpose of this utility model is that: in order to solve existing lithium battery anode ear aluminium flake when welding with nickel sheet more
Difficulty, weld it is unstable and welding precision it is lower, easily occur the problem of the phenomenon that tab fracture during aluminium-to-nickel, mention
For a kind of lithium battery anode ear.
To achieve the above object, the utility model provides the following technical solutions: a kind of lithium battery anode ear, including aluminium flake,
One end of the aluminium flake is provided with welding ends, and the surface of the welding ends is provided with welding groove, the outside setting of the welding ends
There is nickel sheet, gel is provided on the outside of the nickel sheet, the nickel sheet is provided with card slot close to one end of aluminium flake.
Preferably, the quantity of the welding groove is multiple, and the nickel sheet and welding ends pass through laser welding.
Preferably, the card slot matches with aluminium flake.
Preferably, the gel is located at the contact position of nickel sheet and aluminium flake.
Compared with prior art, the utility model has the beneficial effects that the utility model is by the card slot of setting by aluminium flake
Welding ends insertion card slot in, avoid welding when there is the skew of nickel sheet so that welding it is more steady, improve welding precision conjunction
Welding efficiency can be avoided the phenomenon that turning tab easy fracture in nickel process by multiple welding grooves of setting, pass through the pole of setting
Aluminium flake is formed an entirety together with nickel sheet sealing by ear glue, improves the stability of connecting portion.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the main view of the utility model；
Fig. 3 is the structural schematic diagram of the utility model nickel sheet.
In figure: 1, aluminium flake；2, welding ends；3, welding groove；4, nickel sheet；5, gel；6, card slot.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3, a kind of lithium battery anode ear, including aluminium flake 1 are please referred to, one end of aluminium flake 1 is provided with welding ends 2, welding
The surface at end 2 is provided with welding groove 3, and the outside of welding ends 2 is provided with nickel sheet 4, and the outside of nickel sheet 4 is provided with gel 5, nickel sheet
4 are provided with card slot 6 close to one end of aluminium flake 1.
In this implementation: the welding ends 2 of aluminium flake 1 being inserted into card slot 6 by the card slot 6 of setting, avoids nickel occur when welding
The skew of piece 4 improves welding precision and closes welding efficiency so that welding is more steady, can by multiple welding grooves 3 of setting
The phenomenon that turning tab easy fracture in nickel process is avoided, is formed aluminium flake 1 together with the sealing of nickel sheet 4 by the gel 5 of setting
One entirety, improves the stability of connecting portion.
Please emphatically refering to fig. 1, the quantity of welding groove 3 be it is multiple, nickel sheet 4 and welding ends 2 pass through setting by laser welding
Multiple welding grooves 3 can be avoided the phenomenon that turning tab easy fracture in nickel process, reduce defect rate, reduce production cost.
It please focus on refering to Fig. 3, card slot 6 matches with aluminium flake 1, by the way that the welding ends 2 of aluminium flake 1 is inserted into card slot 6 by card slot 6
It is interior, it avoids the skew of nickel sheet 4 occur when welding, so that welding is more steady, improves welding precision and close welding efficiency.
Please be emphatically referring to Fig.2, gel 5 be located at the contact position of nickel sheet 4 and aluminium flake 1, gel 5 is by aluminium flake 1 and nickel
The sealing of piece 4 forms an entirety together, improves the stability of connecting portion.
Working principle: when welding, the welding ends 2 of aluminium flake 1 is inserted into card slot 6 by card slot 6, by laser in welding groove 3
Cooperation under welded, avoid welding when there is the skew of nickel sheet 4 so that welding it is more steady, improve welding precision conjunction
Aluminium flake 1 is formed an entirety together with the sealing of nickel sheet 4 by gel 5, improves the firm of connecting portion by welding efficiency
Property, it can be avoided the phenomenon that turning tab easy fracture in nickel process, reduce defect rate, reduce production cost.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
