Abstract
The invention discloses a kind of explosion-proof lug of lithium battery, including lithium battery and fix the lug being connected with lithium battery, described lug one end electrically connects with lithium battery interior, the other end of lug is connected with lithium battery external electrode metal, described lug constitutes a complete loops with lithium battery, outer member, offering fracture on the sheet metal of described lug, the metal portion of lacking of described fracture side connects whole loop.The explosion-proof lug of a kind of lithium battery of the present invention, as one hole of punching on the bonding jumper of battery pole ear or breach, control lug metal and lack the width in portion, as desired to design hole and the size of breach, make it can only be by a certain size electric current, when current is excessive, metal lacks portion and will be blown as protective tube, when in cell production process or when short circuit occurring during use, the electric current flowing through lug exceedes design load, will disconnect, it is to avoid the accident that blast is hurted sb.'s feelings occurs, promote the market application of lithium battery.
Description
Technical field
The present invention relates to lithium battery pole ear technical field, be specially a kind of explosion-proof lug of lithium battery.
Background technology
The life appearing as we mankind of battery, entertain and work and provide important power supply guarantee;Along with society
Development and the progress of human civilization, one-shot battery gradually will be by due to the shortcoming such as low to pollution, the capacity of environment, to use the time short
Eliminating, the substitute is the secondary cell of the advantages such as pollution-free, capacity big, length in service life, wherein lithium battery is distinctive certainly
Body structure and performance are widely applied to every field, as notebook computer, portable power source, electric tool etc. are exactly therein
Represent.
Lithium ion battery is a kind of secondary cell (rechargeable battery), and it relies primarily on lithium ion and moves between a positive electrode and a negative electrode
Move work.In charge and discharge process, Li+ between two electrodes come and go embed and deintercalation: during charging, Li+ from positive pole deintercalation,
Embedding negative pole through electrolyte, negative pole is in rich lithium state;During electric discharge then on the contrary, battery typically uses the material containing elemental lithium
As electrode, it it is the representative of modern high performance battery;Lithium system battery is divided into lithium battery and lithium ion battery, mobile phone and notebook electricity
What brain used is all lithium ion battery, and usual people's custom is called lithium battery, and real lithium battery is big due to danger, seldom
It is applied to day electronic product;To this end, develop a kind of explosion-proof lug of lithium battery.
Summary of the invention
It is an object of the invention to provide a kind of explosion-proof lug of lithium battery, with asking of solving to propose in above-mentioned background technology
Topic.
For achieving the above object, the present invention provides following technical scheme: a kind of explosion-proof lug of lithium battery, including lithium battery with
And the lug being connected is fixed with lithium battery, described lug one end electrically connects with lithium battery interior, the other end of lug and lithium battery
Outer electrode metal connects, and described lug constitutes a complete loops, on the sheet metal of described lug with lithium battery, outer member
Offering fracture, the metal portion of lacking of described fracture side connects whole loop.
Further, described fracture is breach or punching, and fracture one side of breach type has metal and lacks portion, punching hole type
Fracture dual-side is respectively provided with metal and lacks portion.
Further, the flow conductivity that the width of described fracture lacks portion according to metal is configured.
Further, described breach correspondence metal lacks portion's width is that punching correspondence metal lacks the 1/2 of portion's width.
Compared with prior art, the invention has the beneficial effects as follows:
The explosion-proof lug of a kind of lithium battery of the present invention, as one hole of punching on the bonding jumper of battery pole ear or breach,
Control lug metal and lack the width in portion, as desired to design hole and the size of breach so that it is can only be by a certain size electricity
Stream, when current is excessive, metal lacks portion and will be blown as protective tube, when going out in cell production process or during using
During existing short circuit, the electric current flowing through lug exceedes design load, will disconnect, it is to avoid the accident that blast is hurted sb.'s feelings occur, and has promoted lithium electricity
The market application in pond.
Accompanying drawing explanation
Fig. 1 is lithium battery pole ear structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described,
Obviously, described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based in the present invention
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all
Belong to the scope of protection of the invention.
A kind of explosion-proof lug of lithium battery, including lithium battery 1 and the lug 2 that be connected fixing with lithium battery 1, described lug 2
One end is internal with lithium battery 1 to be electrically connected, and the other end of lug 2 is connected with lithium battery 1 outer electrode metal, described lug 2 and lithium
Battery 1, outer member constitute a complete loops, and the sheet metal of described lug 2 offers fracture 3, described fracture 3 side
Metal lacks portion 4 and connects whole loop.
Described fracture 3 is breach or punching, and fracture one side of breach type has metal and lacks portion 4, the fracture two of punching hole type
Side is respectively provided with metal and lacks portion 4.
The flow conductivity that the width of described fracture 3 lacks portion 4 according to metal is configured.
It is that punching correspondence metal lacks the 1/2 of portion 4 width that described breach correspondence metal lacks portion 4 width.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, permissible
Understand and these embodiments can be carried out multiple change without departing from the principles and spirit of the present invention, revise, replace
And modification, the scope of the present invention be defined by the appended.
