Abstract
The invention discloses an anti-short-circuit lithium battery electrode lug. The anti-short-circuit lithium battery electrode lug comprises a strap-shaped flat conductor. Insulating membranes are arranged on the two sides of the strap-shaped flat conductor respectively. The lower end edge of the insulating membrane on one side is longer than the lower end edge of the insulating membrane on the other side by 1 mm or more. The portion, going beyond the lower edge of the insulating membrane on the other side, of the lower end edge of the insulating membrane on one side is located at the bent position of an outer wrapping electrode lug when the electrode lug is bent. According to the anti-short-circuit lithium battery electrode lug, the lower end edges of the two insulating membranes located on the two sides of the strap-shaped flat conductor are not aligned, the lower end edge of the insulating membrane on one side is longer than the lower end edge of the insulating membrane on the other side by 1 mm or more, the portion, going beyond the lower edge of the insulating membrane on the other side, of the lower end edge of the insulating membrane on one side is located at the bent position of the outer wrapping electrode lug when the electrode lug is bent, the situation that the conductive part is exposed after the electrode lug is bent can be avoided, short-circuit accidents are reduced, and meanwhile the bonding faces of the strap-shaped flat conductor and the insulating membranes can be enlarged so that the insulating films can be not prone to falling.
Description
Technical field
The present invention relates to field of lithium, particularly relate to a kind of against short-circuit lithium battery pole ear.
Background technology
With reference to Fig. 1, lithium battery pole ear is generally by a ribbon metal 1, and the dielectric film 2 being pasted onto strip metal 1 two sides respectively forms.Existing lithium battery pole ear is when producing; dielectric film 2 is generally that symmetry is pasted onto strip metal 1 both sides; when the length of two panels dielectric film 2 is not identical; limit, the lower end alignment of two panels dielectric film 2 is pasted onto strip metal 1 both sides; when lug bending is arranged on lithium battery; dielectric film 2 makes it not contact with lithium battery coiling core for the protection of strip metal 1, as shown in Figure 2, to reduce the danger of short circuit.But with reference to Fig. 2, owing to aliging in the limit, dielectric film 2 lower end of existing lithium battery pole ear, after lug bending, strip metal 1 exposes in bending place, easily causes short circuit; Dielectric film 2 is stressed in bending place simultaneously, and the dielectric film causing dielectric film 2 lower end to be sticked on easily departs from strip metal 1.
With reference to Fig. 3, existing another kind of lithium battery pole ear is linked together by two different strip metal and forms, and two ribbon metals are preferably nickel strap 3 and aluminium strip 4, and dielectric film 2 is arranged on both junction.The dielectric film that after this lithium battery pole ear exists bending equally, strip metal exposes, dielectric film 2 lower end is sticked on easily departs from the problem of strip metal.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind of against short-circuit lithium battery pole ear, the current-carrying part solving lithium battery pole ear generation after bending is installed exposes, the problem be easily short-circuited.
The present invention is the technical scheme solving the employing of its technical problem:
A kind of against short-circuit lithium battery pole ear, comprise strip-like flat conductors, described strip-like flat conductors both sides are respectively provided with a slice dielectric film, and wherein the limit, dielectric film lower end of side is than dielectric film lower end more than the length of side 1mm of opposite side, grow part when lug bending, in the bending place of outer cladding lug.
As the further improvement of technique scheme, described strip-like flat conductors is a ribbon metal.
As the further improvement of technique scheme, described strip-like flat conductors is that two ribbon metals couple together, and described dielectric film is arranged on the junction of two ribbon metals.
The invention has the beneficial effects as follows:
Against short-circuit lithium battery pole ear of the present invention, the limit, two panels dielectric film lower end being positioned at strip-like flat conductors both sides does not line up, wherein the limit, dielectric film lower end of side is than dielectric film lower end more than the length of side 1mm of opposite side, grow part when lug bending in the bending place of outer cladding lug, the current-carrying part conductor caused after can avoiding lug bending exposes, reduce the generation of short circuit accident, the bonding plane of strip-like flat conductors and dielectric film can be increased simultaneously, make dielectric film difficult drop-off.
