Description
Technical field
The utility model belongs to battery pole ear field, and in particular to a kind of lithium ion cell polar ear structure.
Background technique
Tab is a kind of raw material of lithium ion polymer battery product, and tab is exactly to extract positive and negative anodes from battery core
Metallic conductor, i.e. the ear of battery positive and negative polarities be inside battery carry out charge and discharge when contact point, tab be all by
Film and metal tape two parts are combined, and tab metal is divided into three kinds of materials, aluminium (Al), nickel (Ni) copper nickel plating (Ni-Cu),
Gel includes black glue, yellow glue and white glue.
Relative to the lithium battery Rayleigh Taylor of yellow glue and black glue tab, the heat-sealing effect of white glue tab is more preferable, seals
It is more soft afterwards, but the common white glue tab in market often needs to distinguish front and back sides, white glue is generally transparent, in installation process
Carelessness is easy to cause installation anti-, thus the safety accident for causing lithium ion battery to use.
Utility model content
To solve the above problems, solving white glue tab the utility model discloses a kind of lithium ion cell polar ear structure
The problem of obscuring front and back sides during the installation process.
A kind of lithium ion cell polar ear structure, including tab metal, tab white glue, the tab cross section metal are rectangular
Shape, is arranged three layers or five layers of tab white glue in front of tab metal top, and tab metal foot is arranged locating convex block, tab metal with
At least three metal reinforcing wires are set between tab white glue, the locating convex block is operplate printing, locating convex block be lines or
One group of point being located along the same line, the metal reinforcing wire are fixedly linked with tab metal.
As a kind of improvement of the utility model, the thickness of the tab white glue is about 80 μm ~ 100 μm.
As a kind of improvement of the utility model, the metal reinforcing wire be the kidney-shaped operplate printing point being equidistantly positioned or
Person is that thickness is no more than 100 μm.
As a kind of improvement of the utility model, white glue is arranged in the back side of the tab metal and tab white glue connecting portion
Layer.
As a kind of improvement of the utility model, the length of the metal reinforcing wire bottom is greater than the length of tab metal bottom
Degree.
As a kind of improvement of the utility model, the locating convex block is set in front of tab metal and metal reinforcing wire.
The beneficial effects of the utility model are:
A kind of lithium ion cell polar ear structure described in the utility model, including tab metal and tab white glue, tab knot
Structure need to distinguish it is positive and negative, therefore the side of tab metal connecting tab white glue be arranged locating convex block, the locating convex block energy of printing
It is enough that the positive and negative of extreme ear structure is distinguished by touch or machine scans, avoid installation from obscuring, while metal reinforcing wire can add
While strong extreme ear structure current lead-through, increase the toughness of tab metal, at the same can more convenient differentiation extreme ear structure just
Instead, the generation more avoided confusion.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the side left view structural representation of the utility model.
Reference signs list:
1. tab metal, 2. tab white glue, 3. locating convex blocks, 4. metal reinforcing wires.
Specific embodiment
With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate, it should be understood that following specific embodiment parties
Formula is merely to illustrate the utility model rather than limitation the scope of the utility model.It should be noted that making in being described below
Word "front", "rear", "left", "right", "up" and "down" refer to that the direction in attached drawing, word "inner" and "outside" respectively refer to
Be directed towards or far from geometric center of specific component direction.
As shown, a kind of lithium ion cell polar ear structure, including tab metal 1, tab white glue 2, the tab metal
1 section is rectangle, and three layers or five layers of tab white glue 2, the setting positioning of 1 lower part of tab metal are arranged in front of 1 top of tab metal
Convex block 3, is arranged at least three metal reinforcing wires 4 between tab metal 1 and tab white glue 2, the locating convex block 3 is metal printing
Brush, locating convex block 3 are lines or one group of point being located along the same line, the metal reinforcing wire 4 and 1 stationary phase of tab metal
Even.
As shown, a kind of lithium ion cell polar ear structure described in the utility model, including tab metal 1 and tab
White glue 2, extreme ear structure need to distinguish it is positive and negative, therefore the side of 1 connecting tab white glue 2 of tab metal be arranged locating convex block 3, print
The locating convex block 3 of brush can distinguish the positive and negative of extreme ear structure by touch or machine scans, avoid installation from obscuring, while metal
Reinforced wire 4 can increase the toughness of tab metal 1, while can be more convenient while reinforcing extreme ear structure current lead-through
Distinguish positive and negative, the generation more avoided confusion of extreme ear structure.
As shown, the thickness of the tab white glue 2 is about 80 μm ~ 100 μm, the metal reinforcing wire 4 is equidistant sets
The kidney-shaped operplate printing point set is no more than 100 μm for thickness, the volume and thickness of extreme ear structure is controlled on the whole, to lithium
