Abstract
The utility model provides a lug of a lithium battery. The lug comprises a lug body, the lug body is composed of a lug head, a lug tail, and a lug middle part arranged between the lug head and the lug tail, the lug middle part is respectively connected with the lug head and the lug tail, and the width of the lug middle part is smaller than the width of the lug head and the width of the lug tail. The lug of the lithium battery has the beneficial effect that when the outside of the battery has short circuit, and the current is too large, the lug body can fuse as a fuse wire so as to disconnect the contact between the anode and the cathode of the battery, thereby ensuring that the battery cannot burst into flames, even explode.
Description
Technical field
The utility model relates to lithium battery, relates in particular to the lug of lithium battery.
Background technology
Existing cell positive pole ear all is up and down with wide, if under the situation that outside batteries is short-circuited, lug is difficult for fusing, and can't play the effect of protecting battery.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of lug of lithium battery.
The utility model provides a kind of lug of lithium battery; Comprise the lug body; Said lug body is made up of lug head, lug afterbody and the middle part of the lug between said lug head and said lug afterbody; Said lug middle part links to each other with said lug afterbody with said lug head respectively, and said lug middle part width is less than said lug head width and said lug tail width.
As the further improvement of the utility model, said lug middle part width is the 5%-95% of said lug body width.
As the further improvement of the utility model, said lug body is a positive pole ear.
As the further improvement of the utility model, said lug body is processed by aluminum.
The beneficial effect of the utility model is: when short circuit appears in outside batteries, under the excessive situation of electric current, this lug body can fuse as fuse, and the contact between the battery plus-negative plate is broken off, thereby guarantees that battery can catching fire, even blast.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model.
Embodiment
As shown in Figure 1; The utility model discloses a kind of lug of lithium battery; Comprise lug body 1; Said lug body 1 is made up of lug head 2, lug afterbody 3 and the middle part of the lug between said lug head 2 and said lug afterbody 35, and said lug middle part 5 links to each other with said lug afterbody 3 with said lug head 2 respectively, and said lug middle part 5 width are less than said lug head 2 width and said lug afterbody 3 width.
Said lug middle part 5 width are 5%-95% of said lug body 1 width.
Said lug body 1 is a positive pole ear, and said lug body 1 is processed by aluminum.
When short circuit appears in outside batteries, under the excessive situation of electric current, this lug body 1 can fuse as fuse, and the contact between the battery plus-negative plate is broken off, thereby guarantees that battery can catching fire, even blast.
Because the positive pole ear material of battery battery core is an aluminium; And the fusing point of aluminium is lower; We are cut into lug the shape of lug body 1 before soldering polar ear, by lug body 1 alteration of form the sectional area of lug, limited the handling capacity of electric current; When battery generation external short circuit, this lug body 1 can fuse.Simultaneously; During the battery operate as normal, the electric current that lug body 1 also has passes through, and the temperature of lug body 1 is raise; Ability to bear when the electric current during for assurance battery operate as normal passes through with 1 pair of temperature rising of lug body; Should not the 1 sectional area cutting of lug body is narrow, so in the utility model, said lug middle part 5 width are 5%-95% of said lug body 1 width.
When outside batteries is short-circuited; Battery can produce powerful electric current through lug body 1, can produce high temperature simultaneously, and the utility model has limited the handling capacity of electric current; When powerful electric current passes through positive pole ear; The high temperature that is produced can fuse lug body 1 narrow place, is about to depressed part 5 fusing, thus protection battery pack and external equipment.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection range of the utility model.
Claims (4)
1. the lug of a lithium battery; It is characterized in that: comprise the lug body; Said lug body is made up of lug head, lug afterbody and the middle part of the lug between said lug head and said lug afterbody; Said lug middle part links to each other with said lug afterbody with said lug head respectively, and said lug middle part width is less than said lug head width and said lug tail width.
2. lug according to claim 1 is characterized in that: said lug middle part width is the 5%-95% of said lug body width.
