Abstract
The invention discloses a pole piece with tabs. The pole piece comprises a current collector piece, wherein the current collector piece is provided with connected dressing area and blank area; an integrally connected tab area extends in local edge of the blank area; and the tab area and the dressing area are located at two sides of the blank area. Due to the adoption of the tabs integrally connected with the current collector piece, the welding mode of superposing tab pieces on the current collector piece is creatively avoided, the thickness of the pole piece is obviously reduced, the bottleneck that a polymer ultra-thin soft package secondary battery cannot be easily improved towards a smaller thickness direction is broken through; and the pole piece has important practical value and significance in popularization and development of an intelligent IC card with the battery.
Description
Technical field
A kind of the present invention relates to the slimline battery field in intellective IC card, more particularly to pole piece with lug.
Background technology
With the intelligent development of society, various magnetic stripe cards also change towards chip card direction, particularly bank card, at present
Be replaced with chip card from magnetic stripe card on a large scale, and in order to further improve quantity of information and increase confidentiality, it is not far general
Come, the bank card of various chip types, identity card identification card (ID cards), social security card, common reserve fund card can also develop into the intelligence of charged pool
Energy IC-card, thus it is also proposed higher requirement to the slimline battery in card.
But, the ultra-thin secondary battery of soft package of polymer of the prior art, such as lithium ion battery receive its internal structure
Restriction, thickness all in more than 1mm, especially positive/negative plate, be often required for by be superimposed in the way of weld upper corresponding lug,
This just from bottleneck limits the ultra-thin secondary battery of soft package of polymer and is difficult to towards the thinner direction of thickness improve.
Therefore, prior art still has much room for improvement and develops.
The content of the invention
For solving above-mentioned technical problem, the present invention provides a kind of pole piece with lug, the thickness of secondary cell can be caused to become
Obtain thinner.
Technical scheme is as follows：A kind of pole piece with lug, including a collector piece, sets on the collector piece
The dressing area and a clear area being connected is equipped with, wherein：A lug of integrally connected is extended with the edge local of clear area
Area, lug area are located at the both sides of clear area with adjuvant area.
The described pole piece with lug, wherein：The lug area and the interior junction rounding off of clear area.
A kind of pole piece with lug provided by the present invention, as a result of the lug being integrally attached on collector piece,
Innovatively avoid the welding manner to be superimposed upon on collector piece by lug piece, hence it is evident that reduce the thickness of pole piece, break through
The ultra-thin secondary battery of soft package of polymer is difficult to bottleneck improved towards the thinner direction of thickness, for the intellective IC card of charged pool
Popularization and development with important practical value and meaning.
Description of the drawings
Fig. 1 is the axonometric chart of the pole piece with lug of the invention.
Fig. 2 is the explosive view of slimline battery of the present invention.
Fig. 3 is the assembling schematic diagram of slimline battery of the present invention.
Specific embodiment
Below with reference to accompanying drawing, the specific embodiment and embodiment of the present invention are described in detail, described tool
Body embodiment only to explain the present invention, is not intended to limit the specific embodiment of the present invention.
As shown in figure 1, Fig. 1 is the axonometric chart of the pole piece with lug of the invention, the pole piece includes a collector piece 100,
It is provided with the collector piece 100 and is connected up and down（Or left and right is connected）A dressing area 110 and a clear area 120, dressing
It is used for applying coated positive pole material in area 110（Or negative material）, at the edge of clear area 120, locally extend a lug area 130,
Lug area 130 and 120 integrally connected of clear area and consistency of thickness, the bearing of trend in lug area 130 and the direction phase in adjuvant area 110
Instead, i.e. lug area 130 is connected to the opposite side of clear area 120 for adjuvant area 110.
Thus, the pole piece with lug of the invention innovatively employs the lug being integrally attached on collector piece, it is to avoid
Welding manner by lug piece to be superimposed upon on collector piece, hence it is evident that reduce the thickness of pole piece, breach polymer ultra-thin
Secondary battery of soft package is difficult to bottleneck improved towards the thinner direction of thickness so that the thickness of secondary cell can become thinner；
And, the pole piece after improvement can be greatly reduced the production cost and period of pole piece with the one-shot forming by the way of punching.
In the preferred implementation of pole piece of the present invention with lug, the interior connection of the lug area 130 and clear area 120
Locate 123 rounding ofves, for example, can carry out fillet process, in order to reduce possibility of the lug area 130 from fracture of root, and improve
The service life of its blanking die.
Based on the above-mentioned pole piece with lug, the invention allows for a kind of slimline battery, as shown in Fig. 2 Fig. 2 is the present invention
The explosive view of slimline battery, the slimline battery include one before case chip 210, an anode pole piece 220, a barrier film 230, a negative pole pole
Piece 240 and a post package piece 250, with reference to shown in Fig. 3, Fig. 3 is the assembling schematic diagram of slimline battery of the present invention, after assembling, every
Film 230 is located between anode pole piece 220 and cathode pole piece 240, and front case chip 210 is encapsulated in the side of anode pole piece 220, seals afterwards
Load 250 is encapsulated in the side of cathode pole piece 240, and wherein, the cathode pole piece 220 employs any one of above-described embodiment institute
The pole piece with lug stated, and/or, the anode pole piece 240 also uses the band lug any one of above-described embodiment
Pole piece.The thinner battery of the thickness so made, hence it is evident that expand the range of application of the ultra-thin secondary battery of soft package of polymer.
In the preferred implementation of slimline battery of the present invention, in the lug area 223 of the anode pole piece 220, one is provided with
Lug film 224, the two ends of the lug film 224 exceed two sides in 220 lug area 223 of anode pole piece；The cathode pole piece
A lug film 244 is also equipped with 240 lug area 243, and the two ends of the lug film 244 exceed 240 lug of cathode pole piece
Two sides in area 243.
The setting it is preferred that the lug area 243 of the lug area 223 of the anode pole piece 220 and cathode pole piece 240 staggers,
