Abstract
The utility model relates to a cylindrical super capacitor electrode comprising a current collector. The front side surface and the rear side surface of the current collector are coated with active material layers; and the active material layer arranged at one side is broken at the middle portion to form a tab welding zone. The current collector includes a pole piece front end and a pole piece tail end; and the pole piece front end and the pole piece tail end are blank zones that are not coated with any active material layer. The lengths of the pole piece front end and the pole piece tail end are values in a range from 1 to 5 mm; and the portions, where the pole piece front end and the pole piece tail end are located, of the front side surface and rear side surface of the current collector are not coated with the active material layers. According to the scheme, because the blank zones are arranged at the front and tail ends of the electrode, during the electrode transfer process, once the electrode is contacted with other objects or tools, the current collector is firstly contacted without touching active materials at the current collector, thereby reducing power falling phenomenon during the electrode transferring process, reducing a rejection rate caused by super capacitor micro short circuit due to dusts, and lowering the production cost of the super capacitor.
Description
Technical field
The utility model relates to a kind of electrode of super capacitor, relates in particular to a kind of cylinder electrode of super capacitor.
Background technology
Column type ultracapacitor has application prospect very widely as a kind of energy storage device of environmental protection in fields such as the energy, automobile, health care, electronics, military affairs.In recent years, the manufacturing technology of ultracapacitor also makes great progress, but some details in manufacture process affect qualification rate and the quality of ultracapacitor to a great extent.Electrode as shown in Figure 2, in transfer process, the first end portion of electrode need to contact more frequently with operating personnel's hand and frock clamp, after hand or frock clamp and electrode contact, just likely touch the active material on electrode, once touching is comparatively serious, will cause the active material on electrode to depart from, thereby formation dry linting, cause ultracapacitor micro-short circuit, cause the qualification rate of ultracapacitor and overall quality to reduce, this problem is effectively improved always.
Summary of the invention
The purpose of this utility model is to provide a kind of cylinder electrode of super capacitor that can reduce dry linting in electrode transfer process, improve ultracapacitor qualification rate and quality.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of cylinder electrode of super capacitor, comprise collector, leading flank and the trailing flank of collector are coated with active material layer, wherein the active material layer of a side disconnects from middle part and forms tab welding district, it is characterized in that: collector comprises pole piece head end and pole piece end, pole piece head end and pole piece end are white space, do not apply active material layer in this region.
According to described a kind of cylinder electrode of super capacitor, it is characterized in that: the length of described pole piece head end and described pole piece end is 1 ~ 5mm.
According to described a kind of cylinder electrode of super capacitor, it is characterized in that: described collector leading flank and the trailing flank at described pole piece head end and described pole piece end place place all do not apply active material layer.
Cylinder electrode of super capacitor described in the utility model is simple in structure, because the head and end at electrode is provided with white space, therefore, in electrode transfer process, once electrode contacts with other article or utensil, what first touch is collector, and can not touch the active material on collector, thereby reduce the dry linting phenomenon of electrode in transfer process, reduce the scrappage that the ultracapacitor micro-short circuit that causes due to dust causes, promote qualification rate and the total quality of ultracapacitor, reduced the production cost of ultracapacitor.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of current cylinder electrode of super capacitor.
In accompanying drawing:
1, active material layer; 2, collector; 3, tab welding district; 4, pole piece head end; 5, pole piece end.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
A kind of cylinder electrode of super capacitor, as shown in Figure 1, comprise collector 2, the leading flank of collector 2 and trailing flank are coated with active material layer 1, wherein the active material layer 1 of a side disconnects from middle part and forms tab welding district 3, collector 2 comprises pole piece head end 4 and pole piece end 5, and pole piece head end 4 and pole piece end 5 are white space, do not apply active material layer 1 in this region.
In the present embodiment, the length of described pole piece head end 4 and described pole piece end 5 is 1 ~ 5mm.Described collector 2 leading flanks and the trailing flank at described pole piece head end 4 and described pole piece end 5 place places all do not apply active material layer 1.
The electrode of super capacitor that the utility model provides, because head and end is provided with white space, in this region, do not apply active material, make electrode in transfer process when head and end and other object contact, what first touch is the collector of electrode, and can not encounter the active material on collector, thereby reduce the dry linting phenomenon in electrode transfer process, the faults such as the ultracapacitor micro-short circuit bringing due to dust are reduced, the qualification rate and the total quality that have improved ultracapacitor, reduced ultracapacitor cost.
