Abstract
The utility model discloses a cylindrical type supercapacitor pole piece, comprising a pole piece, wherein the pole piece comprises a current collector, an active material layer and a pole lug, wherein the pole lug can be a single pole lug or double pole lugs, and the pole lug is an extension part of foil of the current collector. No matter whether the pole piece is a single-pole-lug pole piece or a double-pole-lug pole piece, one pole lug is always arranged at the central position of the pole piece, the internal resistance of a supercapacitor is reduced, and the power density of the supercapacitor is increased; in addition, since the foil of the current collector is led out and directly served as the pole lug, the pole lug welding process is avoided, the operation efficiency and product quality are improved, and the cylindrical type supercapacitor pole piece is suitable for automated production in large scale.
Description
Technical field
The utility model relates to a kind of pole piece of cylindrical lithium battery, relates in particular to a kind of column type ultracapacitor pole piece.
Background technology
Present traditional ultracapacitor pole piece, no matter monopole ear or two lugs, be all to adopt the one or both ends that aluminium flake is welded on pole piece to stay white region, and the pole piece internal resistance for preparing like this is higher, and power density is lower; And in pole piece manufacturing process, not only stay white region not apply active material and product capacity is reduced, and operation more complicated, production efficiency is also lower, also can be easily because of rosin joint when the welding of lug and pole piece, welding region produces the reason such as burr and causes the ultracapacitor properties of product bad or scrap.
Summary of the invention
The purpose of this utility model is to provide a kind of column type ultracapacitor pole piece, this ultracapacitor pole piece can reduce the product internal resistance, improves power density, also pole piece collector foil directly is used as lug, avoid the tab welding operation, improved operating efficiency and product quality.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of column type ultracapacitor pole piece, comprise pole piece, it is characterized in that: comprise collector, active material layer and lug on pole piece, described lug is monopole ear or Double-pole lug, and lug is the extension of collector foil.
, according to described column type ultracapacitor pole piece, it is characterized in that: when described lug was monopole ear, monopole ear was positioned at the middle of pole piece.
, according to described column type ultracapacitor pole piece, it is characterized in that: when described lug was Double-pole lug, a lug was positioned at the pole piece middle, and a lug is positioned at the pole piece end.
, according to described column type ultracapacitor pole piece, it is characterized in that: described lug is vertical with the long limit of pole piece.
The utility model has the advantages of and be: no matter be monopole ear pole piece or Double-pole lug pole piece, always have a lug to be positioned at the position, middle of pole piece, reduced the ultracapacitor internal resistance, improved the power density of ultracapacitor; Because the foil that adopts collector is directly drawn as lug,, so avoided the tab welding operation, improved operating efficiency and product quality, be fit to large-scale automated production.
Description of drawings
Fig. 1 is the schematic diagram of column type ultracapacitor pole piece monopole ear pole piece.
Fig. 2 is the schematic diagram of column type ultracapacitor pole piece Double-pole lug pole piece.
In accompanying drawing: 1, pole piece; 2, lug.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model as shown in Figure 1, 2, a kind of column type ultracapacitor pole piece, comprise pole piece 1, it is characterized in that: comprise collector, active material layer and lug 2 on pole piece 1, described lug 2 is monopole ear or Double-pole lug, and lug 2 is the extension of collector foil., according to described column type ultracapacitor pole piece, it is characterized in that: when described lug 2 was monopole ear, monopole ear was positioned at the middle of pole piece., according to described column type ultracapacitor pole piece, it is characterized in that: when described lug 2 was Double-pole lug, a lug was positioned at pole piece 1 middle, and a lug is positioned at pole piece 1 end., according to described column type ultracapacitor pole piece, it is characterized in that: described lug 2 is vertical with the long limit of pole piece 1.
Service condition of the present utility model as shown in Figure 1, 2, column type ultracapacitor pole piece, comprise collector, active material layer and lug 2 on pole piece 1, lug 2 on described pole piece 1 can be monopole ear 2, can be also Double-pole lug 2, it is characterized in that: described lug 2 be the extension of collector foil.The lug 2 of described monopole ear pole piece is positioned at the middle of pole piece 1.Lug 2 of described Double-pole lug pole piece is positioned at pole piece 1 middle, and a lug is positioned at the pole piece end.Described lug 2 is vertical with the long limit of pole piece 1.
No matter be monopole ear pole piece or Double-pole lug pole piece, always have a lug to be positioned at the position, middle of pole piece, reduced the internal resistance of ultracapacitor, improved the power density of ultracapacitor; Because the foil that adopts collector is directly drawn as lug,, so avoided the tab welding operation, improved operating efficiency and product quality, be fit to large-scale automated production.
Embodiment recited above is described preferred implementation of the present utility model; not design of the present utility model and protection range are limited; under the prerequisite that does not break away from the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model, all should fall into protection range of the present utility model.
