Abstract
The utility model relates to a negative pole piece of cylindrical super capacitor. The negative pole piece comprises a current collector; the front side surface and the rear side surface of the current collector are coated with active material coating layers; the active material coating layer arranged at one side is broken at the middle portion to form a tab welding zone. The front end of the current collector is a pole piece front end; the front side surface and the rear side surface of the front end of the pole piece are blank zones that are not coated with any active material coating layer. The rear end of the current collector is a pole piece tail end; one side of the pole piece tail end is a blank zone and no active material coating layer is arranged in the zone; the zone and the tab welding zone are arranged at the different sides of the current collector; and the side surface, at the same side with the tab welding zone, of the pole piece tail end is provided with an active material coating layer. Besides, the length of the blank zone of the pole piece tail end is consistent with the perimeter of the last circle of the coiled core; the length of the blank zone of the pole piece front tail is 1 to 4 mm; and the length of the blank zone of the pole piece tail end is 10 to 100 mm.
Description
Technical field
The utility model relates to a kind of ultracapacitor pole piece, relates in particular to a kind of cylinder super capacitor anode pole piece.
Background technology
Column type ultracapacitor has application prospect very widely as a kind of environmental protection energy storage device in fields such as the energy, automobile, health care, electronics, military affairs.Along with scientific and technological progress, the technology of preparing of ultracapacitor also makes great progress, but production technology also treat in further optimization, reduce qualification rate and the quality of ultracapacitor with this.Fig. 2 is the structural representation of the current cylinder super capacitor anode pole piece using, in the time that volume core is just rolled up, because volume pin is thin and cathode pole piece is first reeled, curvature is larger, can cause cathode pole piece dry linting, thereby cause ultracapacitor short circuit, this can reduce conforming product rate and overall quality.
The prices of raw and semifnished materials of ultracapacitor are in recent years high all the time, cause the production cost of ultracapacitor very high, had a strong impact on promoting the use of of ultracapacitor, and these problems are perplexing the manufacturer of ultracapacitor always.
Summary of the invention
The purpose of this utility model is to provide a kind of cylinder super capacitor anode pole piece that can reduce active material use amount, reduction ultracapacitor cost, reduce dry linting while coiling, raising ultracapacitor qualification rate and overall quality.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of cylinder super capacitor anode pole piece, comprise collector, the leading flank of collector and trailing flank are equipped with active material coat, wherein the active material coat of a side is broken as tab welding district from middle part, it is characterized in that: the front end of collector is pole piece head end, leading flank and the trailing flank of pole piece head end are white space, active material coat is not set in this region, the rear end of collector is pole piece tail end, a wherein side of pole piece tail end is white space, active material coat is not set in this region yet, this region and tab welding district are positioned at the heteropleural of collector, be provided with active material coat with the side of the pole piece tail end of tab welding district homonymy.
According to described a kind of cylinder super capacitor anode pole piece, it is characterized in that: the length of the white space of described pole piece tail end is consistent with the girth in volume last week of core.
According to described a kind of cylinder super capacitor anode pole piece, it is characterized in that: the length of the white space of described pole piece head end is 1 ~ 4mm, the length of the white space of described pole piece tail end is 10 ~ 100mm.
The utility model is simple in structure, preparation technology is simple, owing to being provided with white space at pole piece head end and pole piece tail end, is not therefore affecting under the prerequisite of capacity of super capacitor, has reduced the use amount of active material, has reduced the production cost of ultracapacitor; Thereby the white space of pole piece head end can solve volume core while just rolling up curvature cause greatly the problem of pole piece dry linting, reduced the scrappage that the super capacitor short circuit that causes because of dry linting causes, promoted qualification rate and the overall quality of ultracapacitor.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the current cylinder super capacitor anode pole piece using.
In accompanying drawing:
1, active material coat; 2, collector; 3, tab welding district; 4, pole piece head end; 5, pole piece tail end.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
A kind of cylinder super capacitor anode pole piece, as shown in Figure 1, comprise collector 2, the leading flank of collector 2 and trailing flank are equipped with active material coat 1, wherein the active material coat 1 of a side is broken as tab welding district 3 from middle part, the front end of collector 2 is pole piece head end 4, leading flank and the trailing flank of pole piece head end 4 are white space, active material coat 1 is not set in this region, the rear end of collector 2 is pole piece tail end 5, a wherein side of pole piece tail end 5 is white space, active material coat 1 is not set in this region yet, this region and tab welding district 3 are positioned at the heteropleural of collector 2, be provided with active material coat 1 with the side of the pole piece tail end 5 of tab welding district 3 homonymies.
In the present embodiment, the length of the white space of described pole piece tail end 5 is consistent with the girth in volume last week of core.The length of the white space of described pole piece head end 4 is 1 ~ 4mm, and the length of the white space of described pole piece tail end 5 is 10 ~ 100mm.
The super capacitor anode pole piece that the utility model provides, in not reducing capacity of super capacitor, has saved the use amount of active material, thereby has reduced the production cost of ultracapacitor; And, because pole piece head end does not apply active material, so reduced the faults such as the ultracapacitor short circuit that caused because of head end curvature excessive dry linting while coiling, improved qualification rate and the overall quality of ultracapacitor.
