Abstract
The utility model discloses a lithium battery electrode leading structure comprising an electrode mast, a sealing gasket, an anti-rotation gasket and an electrode leaking piece, wherein the anti-rotation gasket is provided with an electrode hole matched with the electrode mast. The lithium battery electrode leading structure is characterized in that the electrode hole is radially provided with 5-8 outward grooves, and the electrode mast penetrates through the electrode hole to be fixedly connected with the anti-rotation gasket. In the lithium battery electrode leading structure, since the electrode hole of the anti-rotation gasket is radially provided with a plurality of outward grooves, while mounting the structure, the anti-rotation gasket is connected with the electrode mast in a riveting expansion manner, and the anti-rotation effect is realized; and the lithium battery electrode leading structure has simple processing technology and low cost.
Description
Technical field
The utility model relates to a kind of lithium battery, relates in particular to a kind of lithium battery extraction electrode structure.
Background technology
In present dynamic lithium battery industry, the battery overwhelming majority is a metal shell, and the electric core in the housing is by positive pole, electrolyte, barrier film, negative pole interval range upon range of composition; Pole piece is provided with lug, and positive pole ear is made up of aluminium foil, and negative lug is made up of Copper Foil; Housing is provided with two electrode fairleads; Be connected with anodal and negative electrode deriving structure respectively, positive and negative electrode drawn shell, so that battery connection in groups.
In the electrode deriving structure, when being connected with lug, electrode column need use the anti-rotation pad, be arranged between brace and the insulating washer, to avoid causing the short circuit in the battery because of the rotation of outside.In the prior art, general anti-rotation pad has two kinds: ⑴ adopts oblate structure, and is as shown in Figure 4; Utilize oblate a pair of straight flange as the anti-rotation face, but actual situation about using is the anti-rotation poor effect; Electrode column is receiving under the bigger external force effect; The electrode column twisting still occurs and drive inner lug distortion, location dislocation will be prone to cause battery to open circuit and short circuit, have potential safety hazard; ⑵ adopt square structure, as shown in Figure 5, i.e. cooperating of square opening and square column, the anti-rotation effect is good, but production cost is high, and processing technology is complicated, needs to change the shape of electrode column, also just improved the production cost of entire cell.
Summary of the invention
The goal of the invention of the utility model provides a kind of lithium battery extraction electrode structure, through the improvement of structure, has good anti-rotation effect, improved safety in utilization, and the processing technology letter is suitable, and is with low cost.
For reaching the foregoing invention purpose; The technical scheme that the utility model adopts is: a kind of lithium battery extraction electrode structure; Comprise electrode column, be sheathed on gasket seal, anti-rotation pad and electrode lead-out tablet on the electrode column, said anti-rotation pad is provided with the electrode hole that matches with said electrode column, and said electrode hole radially outward is provided with 5～8 grooves; Said electrode column is interspersed in this electrode hole, is fixedly connected with said anti-rotation pad.
In the technique scheme, prior art is adopted with being connected of lug in said electrode column bottom, can or be spirally connected through riveted joint; Be provided with gasket seal between lug and the battery container, between gasket seal and the electrode lead-out tablet anti-rotation pad be set, in the utility model; The electrode hole that the power supply pole interts on the said anti-rotation pad radially is being provided with 5～8 grooves of outwards dispersing, and forms as 6 jiaos plum blossom hole etc., when encapsulation; Through the riveting electrode column; Clamp-on in the groove after electrode column is expanded, be crowded with entire electrode holes, to reach the purpose of anti-rotation.This fit need not to change the shape of electrode column, simplified processing technology, and the anti-rotation effect is good, even the electrode column fracture can not rotated yet.
In the technique scheme, said electrode column is through said electrode hole and anti-rotation pad riveted and fixed, and said electrode hole internal diameter cooperates with said electrode column external diameter before the riveted joint.
Further technical scheme is that said groove is uniformly distributed in the electrode hole periphery.
In the technique scheme, said electrode aperture constitutes plum blossom hole to establishing 6 grooves.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
1. the utility model radially outward is provided with groove with electrode hole, through the riveting electrode column, clamp-ons groove after the expansion, reaches the anti-rotation purpose to electrode column, and the square structure comparison with in the past need not to change the electrode column shape, and production technology is simple, low cost of manufacture; Compare with oblate structure in the past, the engagement between the electrode column that dependence groove and expansion are clamp-oned, the anti-rotation effect is better, even rupturing, electrode column can not rotate yet, thus the safety in utilization of raising battery;
2. the utility model is simple in structure, is easy to realize.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment one: shown in Fig. 1～2, a kind of lithium battery extraction electrode structure comprises electrode column 1, is sheathed on gasket seal 2, anti-rotation pad 3 and electrode lead-out tablet 4 on the electrode column 1; Said anti-rotation pad 3 is arranged between said electrode lead-out tablet 4 and the said gasket seal 2; Said anti-rotation pad 3 is provided with the electrode hole 5 that matches with said electrode column 1, and said electrode hole 5 radially outward is provided with 6 grooves 6, constitutes quincunx hole; Before the riveted joint; Electrode hole 5 internal diameters and said electrode column 1 are complementary, and after the riveted joint, electrode column 1 expands and fills electrode hole 5.
During assembling, the bottom of electrode column 1 is connected with the lug of electrode slice, and gasket seal 2 is placed on the electrode column 1; Be arranged between housing 7 and the electrode column 1, anti-rotation pad 3 is sheathed on the electrode column 1 through electrode hole 5, between electrode lead-out tablet 4 and gasket seal 2; After riveting technology; Electrode column 1 is expanded in groove 6, form engagement type connection, thoroughly anti-rotation.
