Abstract
The utility model discloses a battery tab, which comprises a conducting sheet with two concave-convex surfaces. Compared with the prior art, the battery tab effectively lengthens the path of electrolyte penetration after battery packaging and changes the direction of electrolyte penetration by the aid of the conducting sheet with the concave-convex surfaces, thereby being capable of effectively reducing the risk of electrolyte penetration, improving tightness of battery packaging and prolonging the service life of the battery.
Description
Technical field
The utility model relates to a kind of battery pole ear, especially a kind of flexible-packed battery lug with good seal performance.
Background technology
At present, the electric core of flexible-packed battery and electrolyte are generally by the encapsulation of encapsulation paper tinsel, the battery packaging structure that is disclosed for No. 200410098136.7 as Chinese invention patent application on November 4th, 2004 application, it will encapsulate folding, the bonding back of paper tinsel by certain mode and form a seal cavity, electricity core and electrolyte are sealed in the seal cavity, the positive and negative lug of electricity core then exposes to outside the encapsulation paper tinsel, so that be the external circuits power supply.
See also shown in Figure 1ly, be the cutaway view of existing battery pole ear, this lug comprises straight conducting strip 10 and is adhered to the fluid sealant 12 on conducting strip 10 two sides.During packaged battery, electric core places in the encapsulation seal cavity that paper tinsel surrounded, and the fluid sealant 12 of lug is fitted with the tack coat of encapsulation paper tinsel, heats the latter two and is melted in together, and lug stretches out outside the encapsulation paper tinsel.
But there is following defective at least in above-mentioned existing battery pole ear: because the conducting strip 10 of battery pole ear and the contact-making surface between the fluid sealant 12 are flat face, electrolyte oozes out from contact-making surface sometimes, causes battery to reduce useful life.
In view of this, necessaryly provide a kind of battery pole ear that can address the above problem.
The utility model content
The purpose of this utility model is: a kind of flexible-packed battery lug with good seal performance is provided.
To achieve these goals, the utility model provides a kind of battery pole ear, and it comprises conducting strip, and the two sides of conducting strip all is a male and fomale(M﹠F).
As a kind of improvement of the utility model battery pole ear, the two sides of described conducting strip all is bonded with fluid sealant.
As a kind of improvement of the utility model battery pole ear, the two sides of described conducting strip all is provided with projection.
As a kind of improvement of the utility model battery pole ear, the two sides of described conducting strip all is provided with depression.
As a kind of improvement of the utility model battery pole ear, the one side of described conducting strip is provided with depression, and another side is provided with projection.
With respect to prior art, the utility model battery pole ear adopts has the non-flat conducting strip of facing directly, effectively prolonged the permeation pathway of electrolyte after the cell package, changed the infiltration direction of electrolyte, therefore can effectively reduce the risk of electrolyte sepage, improve the sealing of cell package, prolong the useful life of battery.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model battery pole ear and useful technique effect thereof are elaborated, wherein:
Fig. 1 is the cross-sectional schematic of existing battery pole ear.
Fig. 2 is the cross-sectional schematic of the utility model battery pole ear first execution mode.
Fig. 3 is the cross-sectional schematic of the utility model battery pole ear second execution mode.
Embodiment
See also shown in Figure 2ly, first execution mode of the utility model battery pole ear comprises conducting strip 20 and is adhered to the fluid sealant 22 on conducting strip 20 two sides.Wherein, the two sides of conducting strip 20 all is provided with some protruding 200, and the contact-making surface of conducting strip 20 and fluid sealant 22 is non-flat facing directly.Compare with existing battery pole ear, the battery with the encapsulation of the utility model battery pole ear can not only prolong the path of electrolyte permeability, and can change the direction of electrolyte permeability, therefore can effectively reduce the risk of electrolyte sepage, improve the sealing of cell package, prolong the useful life of battery.
See also shown in Figure 3ly, be the cross-sectional schematic of the utility model battery pole ear second execution mode, wherein, the two sides of conducting strip 20a all is provided with some depression 200a, and the contact-making surface of conducting strip 20a and fluid sealant 22a is non-flat facing directly.
Certainly, in other alternate embodiments of the present utility model, the conducting strip of battery pole ear can also simultaneously be provided with depression, another side is provided with projection, and shape, quantity, the size of depression and projection can be adjusted according to actual needs; Also other shapes can be directly conducting strip made,, the purpose of this utility model can be realized as long as the contact-making surface of conducting strip and two sides fluid sealant is not a flat face.
In other execution modes of the present utility model, battery pole ear also can only comprise conducting strip and not establish fluid sealant that conducting strip is directly bonding with the tack coat of encapsulation paper tinsel during encapsulation, at this moment, as long as the two sides of conducting strip is non-flat facing directly, can realize the purpose of this utility model equally.
Through test, compared with prior art, use the flexible-packed battery of the utility model battery pole ear encapsulation, improved 2～7 times its useful life.
Be understandable that, because structure of the present utility model both can be applicable to positive pole ear, also can be applied to negative lug, as long as the material and the lug polarity of the conducting strip of selecting adapt, these all are that those of ordinary skills are easy to realize, so this specification no longer specifies the material of lug polarity and conducting strip.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the utility model just for convenience of description.
