Abstract
The utility model provides a super-capacitor which has advantages of: high welding firmness, no easy circuit breaking or circuit shorting, and relatively low internal resistance. The super-capacitor comprises the components of: a cover board, a housing, a wound coiled core which is sealed in the housing and is obtained through superposing super-capacitor pole plates and a diaphragm, and electrolyte. The super-capacitor pole plates comprise an anode pole plate and a cathode pole plate. The anode pole plate and the cathode pole plate respectively comprise a current collector and active material which is coated on the current collector. One end of each of an anode ear and a cathode ear is connected with a corresponding current collector of the anode pole plate and the cathode pole plate, and the other end is riveted on a corresponding one in the anode pole terminal and the cathode pole terminal of the cover board.
Description
Technical field
The utility model relates to a kind of capacitor, relates in particular to a kind of ultracapacitor.
Background technology
Ultracapacitor is a kind of green energy-storing device of novel energy quick charge/discharge.It has the dual-use function of traditional electrical electrolysis condenser and battery, and its power density is far above battery, and more a lot of soon than battery charging and discharging speed; Energy density is far above traditional electrolytic capacitor.Compare with traditional electrical electrolysis condenser and battery, it is little that ultracapacitor has volume, and energy density is large, discharges and recharges speed fast, has extended cycle life, and discharge power is high, operating temperature range wide (40 ℃ ~ 85 ℃), good reliability and the advantage such as with low cost.Therefore, ultracapacitor has become a kind of fast charging and discharging energy storage device of novel, efficient, practical, environmental protection just.In fields such as the energy, automobile, health care, electronics, military affairs, there is application prospect very widely.
The upper and lower width of cylinder ultracapacitor lug using is at present the same, one end and tab welding, and the other end is riveted on above cover plate pole.Because the both positive and negative polarity lug of cylinder ultracapacitor is drawn in same one end of volume core, if lug is wider, lug area is larger, the easily contact and cause product short circuit of both positive and negative polarity lug, if lug is narrower, lug and pole piece contact area are less, and the internal resistance of ultracapacitor product is higher, and with the welding of pole piece and all insecure with the riveted joint of cover plate, easily open circuit and make product rejection.
Summary of the invention
The purpose of this utility model is to provide a kind of firm welding, is difficult for opening circuit and short circuit, and the lower ultracapacitor of internal resistance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of ultracapacitor, comprise cover plate, housing and be sealed in housing by ultracapacitor pole piece and stacked rolled volume core and the electrolyte forming of barrier film, ultracapacitor pole piece comprises anode pole piece and cathode pole piece, it is characterized in that: described anode pole piece and cathode pole piece comprise collector and be coated in the active material on collector, the collector of one end of positive pole ear and negative lug and anode pole piece and cathode pole piece welds together, the other end is riveted in the Positive Poles and negative pole pole of cover plate.
In this structure, on ultracapacitor pole piece, be designed with lug position, place, lug position is connected with lug, and described lug is divided into tab welding district, the lug riveted joint district at two ends and is positioned at middle lug conduction region, the lug conduction region in the middle of the width in described tab welding district and lug riveted joint district is greater than.
In this structure, the width in described tab welding district and lug riveted joint district is 1.5 ~ 2.5 times of described lug conduction region.
The utility model has the advantages of and be: due to this structure of the present utility model, tab welding district and lug riveted joint district is wider has increased the contact area with pole piece and cover plate pole, reduced product internal resistance, and firm welding, difficult drop-off and avoided opening circuit; Owing to being positioned at, the conduction region in lug centre position is narrow, and area is less, and positive pole ear is difficult for contacting with negative lug, so reduced the generation of short circuit phenomenon, effectively improved overall performance and the fail safe of cylinder ultracapacitor, and method is simple, is widely used.
Accompanying drawing explanation
Fig. 1 is the structural representation of ultracapacitor lug.
In accompanying drawing: 1, ultracapacitor pole piece; 2, lug position; 3, lug riveted joint district; 4, lug conduction region; 5, tab welding district.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model as shown in Figure 1, a kind of ultracapacitor, comprise cover plate, housing and be sealed in housing by ultracapacitor pole piece 1 and stacked rolled volume core and the electrolyte forming of barrier film, ultracapacitor pole piece 1 comprises anode pole piece and cathode pole piece, it is characterized in that: described anode pole piece and cathode pole piece comprise collector and be coated in the active material on collector, the collector of one end of positive pole ear and negative lug and anode pole piece and cathode pole piece welds together, and the other end is riveted in the Positive Poles and negative pole pole of cover plate.In the present embodiment, on ultracapacitor pole piece 1, be designed with lug position 2,2 places, lug position are connected with lug, described lug is divided into tab welding district 5, the lug riveted joint district 3 at two ends and is positioned at middle lug conduction region 4, the lug conduction region 4 in the middle of the width in described tab welding district 5 and lug riveted joint district 3 is greater than.In the present embodiment, the width in described tab welding district 5 and lug riveted joint district 3 is 1.5 ~ 2.5 times of described lug conduction region 4.
By the rolled volume core of anode pole piece, barrier film, the stacked composition of negative plate pole piece, lug riveted joint district is riveted on cover plate Positive Poles and negative pole pole, will roll up core baking, after fluid injection, encapsulation, prepares ultracapacitor finished product.
