Abstract
The utility model is related to a kind of electronic component, and specially lithium battery disc type turns nickel anode ear.Lithium battery disc type turns nickel anode ear, including aluminium strip, nickel strap；Nickel strap is welded on aluminium strip, and the aluminium strip that the two ends of nickel strap are exposed is respectively preceding aluminium strip, rear aluminium strip；Aluminium strip is identical with nickel strap width, described preceding aluminium strip one end, and nickel strap and aluminium strip are got ready to form the first aluminium nickel overlay region using laser welding, and described rear aluminium strip is got ready to form the second aluminium nickel overlay region with the nickel strap other end using laser welding；Have the wide tabs of 4.5mm at the edge of the second aluminium nickel overlay region, tab is PP white glue, using high frequency welding technology by PP white glue weldings on aluminium strip, 0.2 0.5mm in the nickel strap insertion tab of the second aluminium nickel overlay region.The lithium battery disc type that the utility model is provided turns nickel anode ear, the process for cancelling patch 3M glue and folding lug, greatlys save cost of labor, and ensures the planarization on closedtop side, and super thick at anode ear will not be caused to PACK folded plates technique, reduces battery core internal resistance itself.
Description
Technical field
The utility model is related to a kind of electronic component, and specially lithium battery disc type turns nickel anode ear.
Background technology
It is in 3.5- by nickel metal tape and tab position length in reserve that lithium battery disc type anode ear, which turns nickel, on the market at present
4mm, then in back segment process by the way of patch 3M glue rolls over lug again, patch 3M glue is to be rolled over to fix metal tape after lug on top
Edge sealing will not move and be broken aluminium strip.Existing lug mode must be set up two processes, patch 3M glue process and folding lug work
Sequence, generates larger cost of labor, roll over lug when easily produce it is bad, such as lug fracture, lug centre-to-centre spacing deflection it is bad
Etc..And closedtop side out-of-flatness after lug is rolled over, anode ear wants the thickness (i.e. 0.3mm) of thick 3 layers of metal tape, to PACK techniques
Folded plate mode have a significant impact.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of lithium battery disc type and turns nickel anode ear.
Specifically technical scheme is：
Lithium battery disc type turns nickel anode ear, including aluminium strip, nickel strap；Described nickel strap is welded on aluminium strip, the two ends of nickel strap
The aluminium strip exposed is respectively preceding aluminium strip, rear aluminium strip；Described aluminium strip is identical with nickel strap width, described preceding aluminium strip one end, nickel strap
Get ready to form the first aluminium nickel overlay region using laser welding with aluminium strip, described rear aluminium strip uses laser welding with the nickel strap other end
Get ready to form the second aluminium nickel overlay region；There are the wide tabs of 4.5mm at the edge of the second aluminium nickel overlay region, tab is that PP is white
Glue, using high frequency welding technology by PP white glue weldings on aluminium strip, the nickel strap insertion tab of described the second aluminium nickel overlay region
Interior 0.2-0.5mm.
The lithium battery disc type that the utility model is provided turns nickel anode ear, the process for cancelling patch 3M glue and folding lug, saves significantly
Cost of labor has been saved, and has ensured the planarization on closedtop side, super thick at anode ear will not be caused to PACK folded plates technique, reduces battery core
Internal resistance itself.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is described with reference to the drawings.
As shown in figure 1, lithium battery disc type turns nickel anode ear, including aluminium strip, nickel strap 3；Described nickel strap 3 is welded on aluminium strip
On, the aluminium strip that the two ends of nickel strap 3 are exposed is respectively preceding aluminium strip 1, rear aluminium strip 6；Described aluminium strip is identical with the width of nickel strap 3, described
The one end of preceding aluminium strip 1, nickel strap 3 and aluminium strip use the first aluminium nickel overlay region 2 of laser welding formation, described rear aluminium strip 6 and nickel strap 3
The other end is got ready to form the second aluminium nickel overlay region 4 using laser welding；There is 4.5mm wide at the edge of the second aluminium nickel overlay region 4
Tab 5, tab 5 be PP white glue, using high frequency welding technology by PP white glue weldings on aluminium strip, the second described aluminium nickel weight
0.2-0.5mm in the nickel strap insertion tab in folded area 4.
Nickel strap 3 is 4mm, and is embedded in tab 0.2mm, nickel strap 3 is welded on aluminium strip, and nickel strap 3 is embedded in into lug
0.2mm in glue 5, when tab 5 is fused on metal tape, tab 5 can outwards overflow 0.5mm or so, therefore nickel strap 3 has embedding
Enter to tab 5 and reach 0.2-0.5mm, nickel strap 3 can be completely fixed, because reducing its length, so also reducing well
The internal resistance of battery in itself, and save back segment patch double faced adhesive tape and electrode lug folding procedure.
Tab 5 is that white glue is softer, and lug bending process is run among production process, and white glue and then can slightly be bent,
Therefore a bending arc-shaped is played, so aluminium pole ears will not be caused to be broken.
