Background technology
In the generating process of battery, electrical chip forms battery core by winding process, and the lug wherein on electrical chip is overlapping
To form the positive pole of battery core or negative pole.The spacing accuracy of lug can be ensured by machining accuracy, but by winding precision
Influence, lug can be offset with winding and in specified location, while the width of lug in the prior art is equal (attached with reference to specification
Fig. 1), this will cause lug it is possible that can not be completely overlapped the problem of (with reference to Figure of description 2), and then cause overlapping
Lug does not reach the requirement of collector, influences the charge-discharge performance of battery core.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of winding electrical chip, with solve existing lug without
The problem of method is completely overlapped.
The utility model additionally provides the winding battery core and battery using above-mentioned winding electrical chip.
Technical scheme is used by the utility model solves its technical problem：
One kind winding electrical chip, including substrate and some lugs along base panel length direction on substrate, along substrate
Length direction, the width of lug progressively narrows.
It is equal as the further improved procedure of such scheme, the centre-to-centre spacing of adjacent lug.
One kind winding battery core, including above-mentioned winding electrical chip, winding electrical chip are wound centered on most narrow lug, so that
Each lug to broaden successively is overlapping according to order from the inside to the outside, and positioned at internal layer lug without departing from adjacent thereto and be located at outer layer
Lug width range.
As the further improved procedure of such scheme, including two panels winding electrical chip, two panels winding electrical chip difference
As positive pole electrical chip and negative pole electrical chip, positive pole electrical chip staggers along its length with negative pole electrical chip resynchronizes winding, just
Lug on the electrical chip of pole overlaps to form positive pole, and the lug on negative pole electrical chip overlaps to form negative pole.
A kind of battery, including above-mentioned winding battery core.
The beneficial effect of this type is：
By setting the multiple lugs progressively narrowed along substrate direction, even if ensureing that lug occurs partially in winding process
Move, the lug that can also be avoided positioned at internal layer exceeds the width range of lug adjacent thereto and positioned at its outer layer, so as to realize
Each lug it is completely overlapped, ensure the charge-discharge performance of battery core.

Embodiment
Design, concrete structure and caused technique effect of the present utility model are carried out below with reference to embodiment and accompanying drawing
Clear, complete description, to be completely understood by the purpose of this utility model, scheme and effect.It should be noted that do not conflicting
In the case of, the feature in embodiment and embodiment in the application can be mutually combined.
It should be noted that unless otherwise specified, when a certain feature is referred to as " fixing ", " connection " in another feature,
It can directly fix, be connected in another feature, can also indirectly fix, be connected in another feature.In addition, this
The descriptions such as the up, down, left, right, before and after used in utility model are only relative to each composition portion of the utility model in accompanying drawing
For the mutual alignment relation divided.
In addition, unless otherwise defined, the technology of all of technologies and scientific terms used here by the article and the art
The implication that personnel are generally understood that is identical.Term used in the description is intended merely to describe specific embodiment herein, without
It is to limit the present invention.Term as used herein " and/or " include the arbitrary of one or more related Listed Items
Combination.
Reference picture 1, show the schematic diagram of electrical chip in the prior art.As illustrated, existing electrical chip includes substrate 1
And some lugs 2 along the length direction of substrate 1 on substrate 1, wherein the width of each lug 2 is equal.Because electrical chip exists
Winding precision in winding process can be influenceed (such as the deflection of electrical chip crooked position, between lap by factors
Gap etc.), it is difficult to ensure precision, therefore the battery core after winding is easy to situation as shown in Figure 2 and Figure 3 occur, i.e., lug is because of left and right
Skew and can not be completely overlapped, cause overlapping lug not reach the requirement of collector, influence the charge-discharge performance of battery core.
Based on this, the utility model discloses one kind to wind electrical chip, reference picture 4, shows the utility model winding electricity
The schematic diagram of chip one embodiment.As illustrated, electrical chip in the utility model equally includes substrate 1 and lug 2, its with
The difference of prior art includes：Along the length direction of substrate 1, the width of lug 2 progressively narrows.
Further, the centre-to-centre spacing of adjacent lug 2 is equal.
Reference picture 5, Fig. 6, Fig. 5 show the schematic diagram of the utility model winding battery core one embodiment, and Fig. 6 shows this
Utility model winds the top view of battery core, illustrate only overlapping lug in figure and conceals substrate sections.As illustrated, this reality
The battery core applied in example is formed using two panels identical winding electrical chip winding, and the two panels winds electrical chip respectively as positive pole battery core
Piece and negative pole electrical chip.Specifically, positive pole electrical chip staggers along the length direction of substrate 1 first with negative pole electrical chip, stagger away from
From the spacing less than adjacent lug 2, then synchronously wound centered on most narrow lug 2 again, so that each lug 2 to broaden successively
Overlapping according to order from the inside to the outside, the lug 2 on positive pole electrical chip overlaps to form positive pole 3, and the lug 2 on negative pole electrical chip is overlapping
Form negative pole 4.
Because the width of lug 2 progressively broadens from the inside to the outside, therefore even if lug shifts, it is ensured that positioned at internal layer
Lug without departing from it is adjacent thereto and positioned at its outer layer lug width range, you can realize the completely overlapped of each lug,
Ensure the charge-discharge performance of battery core.
In addition, the invention also discloses a kind of battery using above-mentioned winding battery core.
Above is preferably implement to be illustrated to of the present utility model, but the invention is not limited to the reality
Example is applied, those skilled in the art can also make a variety of equivalent variations on the premise of without prejudice to the utility model spirit
Or replace, these equivalent deformations or replacement are all contained in the application claim limited range.
