Abstract
The invention discloses a kind of negative electrode for lithium ion battery lug assistor, including square nickel sheet and rectangle high temperature gummed tape, square hollow out is offered on the high temperature gummed tape, the small 2mm of the length of side of the side ratio nickel sheet of the square hollow out, four sides of the nickel sheet are adhered on the high temperature gummed tape at square hollow out edge.The advantage is that：Cost of the present invention is relatively low, simple structure, and the negative copper foil lug of fragility can be aided in complete ultra-sonic welded, reduces the possibility of lug tear, the process of outside lug insulation is completed simultaneously, the step of reducing individually winding adhesive tape, reduces technological process, reduces production cost.
Description
Technical field
The present invention relates to technical field of lithium ion, particularly a kind of negative electrode for lithium ion battery lug assistor.
Background technology
Attention with the continuous developing development of new energy field and country to lithium ion battery industry, lithium ion battery
Technology has obtained significant progress, and various lithium ion battery suppliers also arise at the historic moment.Lithium-ion electric common on the market at present
Pond can be divided into column lithium ion battery, rectangular lithium ion battery and soft bag lithium ionic cell by shape.Wherein square lithium from
Sub- battery is favored because PACK assemblings are easy to by numerous suppliers.
With reference to preparation technology and battery performance, it is common lithium electricity that the lithium battery with multi pole ears being made is wound after laser die cutting
Pond battery core.Although the method technological process is simple, battery performance is high, it is necessary to use ultrasound during prepared by battery
Solder technology welds together multi pole ears.Negative lug is Copper Foil, and Copper Foil is softer thin, orlop pole during lug ultra-sonic welded
Easily there are the abnormal conditions such as tear, be broken in ear.Also need to wind adhesive tape at negative lug when shell is entered simultaneously, prevent negative pole
Lug is connected with aluminum hull when bending into shell and causes battery short circuit.In view of production cost, either lug tear is still prevented
Short circuit winding adhesive tape, will all increase material cost and cost of labor.
The content of the invention
The cost brought it is an object of the invention to provide a kind of particularity that can solve the problem that negative lug is added in problem, can carry
Negative lug ultra-sonic welded effect is risen, the negative electrode for lithium ion battery lug assistor of the possibility of lug tear is reduced.
The technical scheme adopted by the invention to solve the technical problem is that：
A kind of negative electrode for lithium ion battery lug assistor, including square nickel sheet and rectangle high temperature gummed tape, its innovative point exist
In：Offer square hollow out on the high temperature gummed tape, the length of side small 2mm of the side ratio nickel sheet of the square hollow out is described
Four sides of nickel sheet are adhered on the high temperature gummed tape at square hollow out edge.
Further, the nickel sheet is located at the surface of square hollow out.
Beneficial effects of the present invention are as follows：
Cost of the present invention is relatively low, simple structure, and the negative copper foil lug of fragility can be aided in complete ultra-sonic welded, reduces lug and tears
The possibility split, while completing the process of outside lug insulation, reduces the step of individually winding adhesive tape, reduces technological process,
Reduce production cost.
Brief description of the drawings
The present invention is described in further details with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the invention.
In figure：1 nickel sheet, 2 high temperature gummed tapes, 3 square hollow outs.
Specific embodiment
A kind of negative electrode for lithium ion battery lug assistor, including square nickel sheet 1 and rectangle high temperature gummed tape 2, high temperature
Square hollow out 3, the small 2mm of the length of side of the side ratio nickel sheet 1 of square hollow out 3, the four sides adhesion of nickel sheet 1 are offered on adhesive tape 2
In on the high temperature gummed tape 2 at the edge of square hollow out 3, and middle hollow out is without adhesive tape.When lithium ionic cell cathode ear pole is welded, auxiliary
Below negative lug, the viscosity that assistor passes through adhesive tape is bonded in orlop negative lug device pad, the both sides of high temperature gummed tape 2
Wide 2mm more each than negative lug, nickel sheet 1 is in negative lug lower end end；Ultrasonic bond contact in the surface of nickel sheet, so in ultrasound
During welding, the bottom pad of negative lug Copper Foil has gone up one layer of nickel sheet 1, reduces the possibility of lug tear；Weld simultaneously after the completion of,
Turned on high temperature gummed tape 2, enwind the effect that negative lug reaches outside lug insulation.The assistor can aid in the negative pole copper of fragility
Paper tinsel lug completes ultra-sonic welded, reduces the possibility of lug tear, while completing the process of outside lug insulation, reduces and individually twines
The step of around adhesive tape, technological process is reduced, reduce production cost.
The above is the preferred embodiment of the present invention, it is impossible to the interest field of the present invention is limited with this.Should refer to
Go out, for those skilled in the art, technical scheme is modified or equivalent, all
Protection scope of the present invention is not departed from.
