The electrode of the various aspects of performance such as capacity, charge/discharge rates and battery become the class of those skilled in the art's research
Topic.
Utility model content
In view of this, this utility model be directed to a kind of do not change this flexible lithium ion battery flexible,
The battery electrode made in the case of main structure and processing and fabricating are simple and the battery with this electrode, to carry
The various aspects of performance such as high battery conductive performance, capacity, charge-discharge velocity.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that
A kind of flexible lithium ion battery electrode, including conductive base, described conductive base is provided with reserved pole
Ear weld part, described conductive base part in addition to reserved tab welding portion is coated with active material
Layer, described reserved tab welding portion is located along on the continuous print strip that coiling direction is arranged.
There is the battery of above-mentioned electrode, including anelectrode and negative electrode and barrier film between the two, described just
It is contrary that electrode reserves tab welding position and described negative electrode reserves that tab welding position is positioned at after winding
Direction, welds after respectively the reserved lug position welding overlaped after winding being become one again
Connect final lug lead-in wire.
Described reserved tab welding position is to cut out at interval of certain distance on described strip conductive base
The spaced multiple positions of confluxing formed after cutting or wash out a part.
There is the battery of above-mentioned electrode, including anelectrode and negative electrode and barrier film between the two, described just
It is same that electrode reserves tab welding position and described negative electrode reserves that tab welding position is positioned at after winding
Side, and described anelectrode reserves tab welding position and described negative electrode is reserved the dislocation of tab welding position and set
Putting, the reserved tab welding position of anelectrode and negative electrode overlaps, after stacking respectively after the coiling
Positive and negative electrode reserve the interval >=2mm at tab welding position, respectively to overlaping after winding
Reserved lug position carry out welding become one after weld final lug lead-in wire again.
Relative to prior art, flexible electrode described in the utility model has the advantage that
This utility model is by directly supplying the later stage by the way of reserved tab welding position on conductive base
Soldering polar ear, be not wipe off as conventional batteries a part coating active substance after again at conductive base
Upper soldering polar ear, the battery conductive performance so produced, capacity and charge-discharge velocity aspect have the biggest
Lifting, and technique is simple.

Detailed description of the invention
It should be noted that in the case of not conflicting, in embodiment in this utility model and embodiment
Feature can be mutually combined.
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
A kind of flexible lithium ion battery electrode, including conductive base, described conductive base is provided with reserved pole
Ear weld part, described conductive base part in addition to reserved tab welding portion is coated with active material
Layer, described reserved tab welding portion is located along on the continuous print strip that coiling direction is arranged, say, that
The when of coating active material layer, staying one to be not coated by active material, after winding, lug is just welded on not
There are the correct position after the multiple-layer stacked on this of coating active material, convenient processing, multilamellar simultaneously
Soldering polar ear again after superposition, has the biggest proposing to battery conductive performance, capacity and charge/discharge rates aspect
Rise.
There is the battery of above-mentioned electrode, including anelectrode and negative electrode and barrier film between the two, described just
It is contrary that electrode reserves tab welding position and described negative electrode reserves that tab welding position is positioned at after winding
Direction, welds after respectively the reserved lug position welding overlaped after winding being become one again
Connect final lug lead-in wire.As shown in Figure 1.To ensure that both positive and negative polarity will not short circuit, conveniently processing.
Described reserved tab welding position is to cut out at interval of certain distance on described strip conductive base
The spaced multiple positions of confluxing formed after cutting or wash out a part.Thus lug can be arranged
At homonymy, to reduce the volume of battery.Cutting or the part washed out can be made variously-shaped as required,
Such as rectangle, square, arc etc..
There is the battery of above-mentioned electrode, including anelectrode 1 and negative electrode 2 and barrier film between the two 3,
Described anelectrode reserves tab welding portion 4 and described negative electrode is reserved tab welding portion 5 and is positioned at the same side,
And described anelectrode reserves tab welding portion 4 and described negative electrode is reserved tab welding portion 5 and shifted to install.
As shown in Figure 2.Anelectrode 1 reserves tab welding position and negative electrode 2 is reserved the dislocation of tab welding portion and set
Put tension force during curvature and spooling length, the winding that can be calculated both positive and negative polarity different parts by winding method
Obtain with optimum flow concentration path and the degree of registration of electric current on electrode；Or the simplest directly method is
Directly winding does not has die-cut reserved limit, and on reserved limit, correct position directly punches out the shape of needs,
Then open core, choose suitable reserved location according to electric current optimum flow concentration path and measure calculating；
Both the above method all can obtain the most reserved lug position.
Flexible battery can be realized by flexible electrode, it is possible to by the electrode before winding or lamination
