Abstract
The utility model provides a novel Li-ion polymer battery pole piece and pole ear structure, comprising a pole piece and a pole ear which is connected with the pole piece, wherein the pole ear is a metal strap, pole ear glue is adhered at the end of the pole ear, where the pole piece is exposed, the pole ear glue is T-shaped and comprises a horizontal area and a longitudinal area, the horizontal width of the horizontal area is larger than the horizontal width of the metal strap, the longitudinal area is between the horizontal area and the edge of the pole piece, the width of the longitudinal area is equal to the width of the metal strap, and the horizontal area and the longitudinal area are in an integrated structure. The novel Li-ion polymer battery pole piece and pole ear structure has the following beneficial effects that the novel Li-ion polymer battery pole piece and pole ear structure thoroughly solves the problem of filling the gap position by changing the pole ear structure, can save insulated gummed paper and increase the product competitiveness, and is simple in structure, low in production cost and easy for mass production.
Description
Technical field
The utility model relates to a kind of lug, especially relates to the lug that a kind of polymer Li-ion battery is used.
Background technology
The electric core of polymer Li-ion battery (being the Soft Roll lithium ion battery) is mainly by pole piece, barrier film, and lug, plastic-aluminum packaging film is formed, wherein this barrier film is at interval between every positive plate and negative plate, lug is welded on the pole piece with as the external external output current of afflux conductor of this lithium-ion electric core, tow sides in the middle part of the metal tape of lug are the overlapping lug glue (cpp glue) that is pasted with insulation all, plastic-aluminum packaging film is wrapped in pole piece, the outer surface of the electric core body that barrier film is formed, when encapsulation, the aluminum-plastic packaged film inner layer CPP glue of this outer surface and the lug glue on the lug are heated and are welded together, thereby realize the sealed package of electric core.In plastic-aluminum packaging film inside electrolyte is housed also, this electrolyte soaks into the space at barrier film and pole piece.
Because polymer Li-ion battery fuses to reach the effect of sealing with heat-sealing by lug glue glue (CPP glue) and plastic-aluminum packaging film, in the design because the big pole piece width of barrier film width, so lug glue must leave certain interval with pole piece, but the existence of this gap leaves the potential safety hazard that positive/negative plate dislocation etc. causes both positive and negative polarity, common way was pasted the insulation gummed paper to reach the insulation purpose for listening in the industry, but because gap digit very narrow (0.5-2mm), be difficult to control in the processing procedure process, therefore not from eliminate safe hidden trouble at all.
The utility model content
The utility model proposes a kind of novel lug at above-mentioned ubiquitous shortcoming.
A kind of novel Soft Roll polymer Li-ion battery pole piece and extreme ear structure, comprise pole piece and the lug that is connected with pole piece, this lug is metal tape, expose the pole piece end at lug and be pasted with lug glue, described lug glue is the T type, comprise horizontal district and vertical district, the transverse width in horizontal district is greater than the metal tape transverse width, and vertical district is positioned between horizontal district and the pole piece edge.
Preferably, the width in described vertical district is consistent with the width of metal tape.
Preferably, described horizontal district is integrated with vertical district.
In sum, the utlity model has following significant beneficial effect:
(1) the application has thoroughly solved the problem of the position of plugging the gap by the change extreme ear structure;
(2) the application can save the insulation gummed paper, improves competitiveness of product;
(3) simple for structure, production cost is low, is easy to large-scale production.
Figure of description
Accompanying drawing 1 is a kind of novel extreme ear structure schematic diagram described in the utility model.
Embodiment
In order to allow those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, a kind of novel Soft Roll polymer Li-ion battery pole piece and extreme ear structure, the lug 2 that comprises pole piece 1 and be connected with pole piece, this lug is metal tape, expose the pole piece end at lug and be pasted with lug glue 3, described lug glue is the T type, comprises horizontal district 31 and vertical district 32, the transverse width in horizontal district is greater than the metal tape transverse width, and vertical district is positioned between horizontal district and the pole piece edge.The width in described vertical district is consistent with the width of metal tape.
Described horizontal district and vertical district are integrated.
The horizontal district of machine ear is with existing lug shape effect unanimity, and it act as the alternative insulation gummed paper that is attached on the metal tape vertical district.Existing lug must leave certain interval with pole piece, but the existence of this gap leaves the potential safety hazard that positive/negative plate dislocation etc. causes both positive and negative polarity, common way was pasted the insulation gummed paper to reach the insulation purpose for listening in the industry, we use the vertical district of lug to realize this purpose, and have avoided pasting " owing to being difficult in the processing procedure process that gap digit very narrow (0.5-2mm) causes control " problem that the insulation gummed paper runs into.
The utility model structure can be on the basis of in the past processing technology, add long ear-pole glue, after lug and metal tape are pasted and are finished, the unnecessary lug glue in metal tape both sides is die-cut, when producing pole piece spot welding lug, what position district and pole piece were stayed in spot welding stays position welding mutually, and the existence of this lug glue can be played the effect of insulation, the problem of the safety of avoiding pole piece to misplace causing.
Need to prove; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these changes and distortion all should belong to the protection range of the appended claim of the utility model.
