Description
Technical field
The utility model relates to technical field of lithium batteries, in particular to a kind of lithium battery tab.
Background technique
Tab is a kind of raw material of lithium ion polymer battery product.Battery divides positive and negative anodes, and tab is exactly from electricity
The metallic conductor for extracting positive and negative anodes in core, the popular ear for saying battery positive and negative polarities are connecing when carrying out charge and discharge
Contact, when lithium battery large-scale use, the security performance of tab is then badly in need of paying close attention to, and therefore, invents a kind of lithium battery tab
It is necessary to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of lithium battery tabs, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions: a kind of lithium battery tab, including tab master
Body, the tab main body middle part are equipped with head end tab, the metal tape other side through metal tape, the metal tape side is equipped with
Equipped with tail end tab, fuse metal silk, the circular fuse metal silk are uniformly provided between the head end tab and tail end tab
It is set on the outside of metal tape, the head end tab and tail end tab are wrapped around equipped with isolation film, and the isolation film wraps around
Equipped with insulation film, the insulation film is wrapped around equipped with fireprotection layer, and plastic-aluminum packaging film is equipped on the outside of the fireprotection layer.
Preferably, the head end tab and tail end tab are made of copper plating nickel material.
Preferably, the isolation film is made of sulfur hexafluoride material.
Preferably, the insulation film is mixed by melanin, polyethylene and thermoplastic resin.
Preferably, the fireprotection layer is set as fireproof gum, and the fireproof gum is uniformly applied to insulation film in aluminum-plastic packaged
Between film.
Preferably, the head end tab, tail end tab and isolation film are integration setting.
The technical effect and advantage of the utility model: head end tab and tail end pole are made by using copper plating nickel material
Ear, it is stronger that copper plates nickel material acid corrosion-resistant, and peeling force, much higher than tab made of script fine copper, use scope is more extensive,
By being equipped with fuse metal silk, when short-circuit conditions occur, then fuse metal silk fuses when temperature is higher than fuse metal silk fusing point,
Avoid because temperature is excessively high cause cells burst even explode the phenomenon that, play preferable protecting effect, by be equipped with fireprotection layer
And isolation film, isolation film are made of sulfur hexafluoride material, have excellent thermal stability and chemical stability, while fireproof gum can
To play good flame retardant effect, whole flameproof effect is improved, to ensure that whole stability.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the part A sectional view of the utility model；
In figure: 1 tab main body, 2 metal tapes, 3 head end tabs, 4 tail end tabs, 5 fuse metal silks, 6 isolation films, 7 insulation
Film, 8 fireprotection layers, 9 plastic-aluminum packaging films.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of lithium battery tab as shown in Figs. 1-2, including tab main body 1, the tab
Through metal tape 2 is equipped in the middle part of main body 1,2 side of metal tape is equipped with head end tab 3, and 2 other side of metal tape is equipped with tail
Tab 4 is held, fuse metal silk 5 is uniformly provided between the head end tab 3 and tail end tab 4, the fuse metal silk 5 is set to
2 outside of metal tape, the head end tab 3 and tail end tab 4 are wrapped around equipped with isolation film 6, and the isolation film 6, which wraps around, to be set
There is insulation film 7, the insulation film 7 is wrapped around equipped with fireprotection layer 8, equipped with plastic-aluminum packaging film 9 on the outside of the fireprotection layer 8.
The head end tab 3 and tail end tab 4 are made of copper plating nickel material, and copper plating nickel material acid corrosion-resistant is stronger, and
Peeling force is much higher than tab made of script fine copper, and use scope is more extensive, and the isolation film 6 is by sulfur hexafluoride material system
At with excellent thermal stability and chemical stability, the insulation film 7 is mixed by melanin, polyethylene and thermoplastic resin
Conjunction is made, and the fireprotection layer 8 is set as fireproof gum, the fireproof gum be uniformly applied to insulation film 7 in plastic-aluminum packaging film 9 it
Between, fireproof gum can play good flame retardant effect, whole flameproof effect is improved, thus ensure that whole stability, institute
Head end tab 3, tail end tab 4 and isolation film 6 are stated as integration setting.
This practical working principle: head end tab 3 and tail end tab 4 are made of copper plating nickel material, and it is acidproof that copper plates nickel material
Corrode stronger, and peeling force, much higher than tab made of script fine copper, use scope is more extensive, when short-circuit conditions occur,
Then fuse metal silk 5 voluntarily fuses when temperature is higher than 5 fusing point of fuse metal silk, avoids causing cells burst very because temperature is excessively high
