Abstract
The utility model discloses connecting structure with pole ears and a cover cap. The connecting structure with the pole ears and the cover cap comprises pole pieces. At least two or more blank spaces are arranged on the pole pieces, wherein each of the blank spaces is respectively connected in welded mode with the pole ears and a gummed paper is pasted on each pair of the pole ears. The connecting structure with the pole ears and the cover cap is characterized in that the pole ears on the blank spaces is connected in a welded mode with one end of an aluminum belt by means of the laser welding connection, the other end of the aluminum belt is connected with the cover cap in a welded mode. The connecting structure with the pole ears and the cover cap has the advantages of being simple in structure, convenient to connect in a welded mode, capable of reducing the spaces for connecting the pole ears and the cover cap, and meanwhile reducing the internal resistance of cell so as to improve the discharging ability of the cell.
Description
Technical field
The utility model relates to the syndeton of a kind of lithium ion battery parts and parts, is specifically related to a kind of have a plurality of lugs and block syndeton.
Background technology
In recent years, also more and more higher to the discharge performance requirement of lithium ion battery along with the fast development of electric tool and IT information products, but present lithium ion battery all is difficult to reach the discharge capability that self carries; Effect and the lug of lithium-ion electric tank discharge have close relationship, and when a plurality of lug of welding, it is even to be conducive to electric current, reduces internal resistance, thereby improves discharge capability.The lithium ion battery that a plurality of lugs are also arranged in the market because the area of cell cover is limited, is connecting the fixing of very difficult realization lug and loam cake, thereby is often causing the sealing-off because of lug and loam cake, causes battery to damage.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, convenient welding, can reduces lug and block connection space, can also reduce the internal resistance of cell simultaneously, thereby improve the lithium ion battery with a plurality of lugs of battery discharge ability.
Have a plurality of lugs and block syndeton, comprise pole piece, at least be provided with two or more the white area of staying on the described pole piece, wherein each stays and welds respectively a lug on the white area, paste gummed paper on each lug, described pole piece is behind coiling, and lug and lug are mutually handed over to frustrate and drawn close, it is characterized in that: describedly stay the lug on the white area to be welded on an end of aluminium strip by the mode of laser welding, its other end then is welded on the block.
The white area of staying on the described pole piece equates with staying the distance between the white area.
The beneficial effects of the utility model are: simple in structure, convenient welding is covering by the tab welding of aluminium strip with two or more, thereby reduces the bonding area of loam cake, can reduce the internal resistance of battery simultaneously, thereby improves the battery discharge ability.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model pole piece coiling structural representation;
Fig. 3 is the utility model pole piece and the location diagram that stays the white area.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As Figure 1-3: have a plurality of lugs and block syndeton, comprise pole piece 1, what be provided with at least two or more on the pole piece 1 stays white area 2, wherein each stays and welds respectively a lug 3 on the white area 2, paste gummed paper 4 on each lug 3, pole piece 1 is behind coiling, lug 3a and lug 3b mutually hand over to frustrate and draw close, stay lug 3 on the white area 2 to be welded on an end of aluminium strip 5 by the laser welding mode, its other end then is welded on the block 6, take aluminium strip 5 as bridge two or more lug 3 is welded on the block 6, thus the bonding area of minimizing block 6, can reduce simultaneously the internal resistance of battery, thereby improve the battery discharge ability.
The white area 2 of staying on the pole piece 1 equates with staying the distance between the white area 2.
Be welded on the block 6 by the lug 3 of aluminium strip 5 with two or more,
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
