Technical field
The utility model relates to capacitor technology field, particularly a kind of high tension super capacitor.
Background technology
Ultracapacitor is a kind of Novel energy storage apparatus between traditional capacitor and storage battery.Compared with traditional capacitor, it has larger capacity and the energy of Geng Gao.Compared with storage battery, it has high power density, extremely long cycle life, better rate charge-discharge performance and wider operating temperature range.In addition, ultracapacitor environmental protection is pollution-free, non-maintaining.Therefore, it has huge using value and market potential in various fields such as traffic, electric power, communication, national defence, consumption electronic products.
The operating voltage of ultracapacitor is 2.5 or 2.7V.In use if desired improve voltage to export, need the super capacitor monomer of some to be carried out series connection and form module.Series mould set requires the capacity of ultracapacitor, internal resistance, and cycle life consistency is high.The monomer voltage of raising ultracapacitor can reduce the amount of monomer in series mould set, reduces in module group assembling process the conforming requirement of monomer.
Utility model content
Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model is to provide a kind of high tension super capacitor, makes it have operating voltage high, can reduce the amount of monomer in series mould set.
Technical scheme: in order to realize foregoing invention object, the technical solution adopted in the utility model is as follows:
A kind of high tension super capacitor, comprises housing, upper cover, winding battery core, plus plate current-collecting body, negative current collector and electrolyte: described housing is the hollow circular cylinder of top end opening, bottom end closure; Described upper cover and housing top margin are tightly connected, and are provided with insulated enclosure packing ring in junction; Described winding battery core is located in described housing, and tile superimposed by pole piece and barrier film according to the order up and down of positive plate, barrier film, negative plate, barrier film, then winding forms; All leave the blank lug identical with pole piece length at the side of positive/negative plate longitudinal direction, after having reeled, winding battery core is put into housing, anode ear is positioned at the top of housing, and negative electrode lug is positioned at the bottom of housing; Described plus plate current-collecting body welds with anode ear, described negative current collector and negative pole lug welding; Described electrolyte is located at enclosure interior, infiltrates winding battery core.
Diameter 60 ± the 1mm of described hollow circular cylinder, high 51 ± 1mm.
Cover on described and be provided with explosion-proof valve.
The width that the pole piece of described winding battery core scribbles the position of slurry is identical with the width of barrier film, and during winding, the position that barrier film and pole piece scribble slurry is overlapping.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, high tension super capacitor, main structural components comprises housing 1, upper cover 2, winding battery core 5, plus plate current-collecting body, negative current collector and electrolyte etc.Housing 1 is the hollow circular cylinder of top end opening, bottom end closure, diameter 60 ± 1mm, high 51 ± 1mm.Upper cover 2, is tightly connected with housing 1 top margin, is provided with insulated enclosure packing ring 3 in the two junction, and is provided with explosion-proof valve 4 upper covering.Winding battery core 5, is placed in housing 1, and tile superimposed by pole piece and barrier film according to the order up and down of positive plate 51, barrier film 52, negative plate 53, barrier film 51, then winding forms.All leave the blank lug identical with pole piece length at the side of positive/negative plate longitudinal direction, after having reeled, winding battery core 5 is put into housing 1, anode ear 511 is positioned at the top of housing 1, and negative electrode lug 531 is positioned at the bottom of housing 1.Width pole piece scribbling the position of slurry is identical with the width of barrier film 52, and during winding, the position that barrier film 52 and pole piece scribble slurry is overlapping.Plus plate current-collecting body, negative current collector, its respectively with anode ear, negative pole lug welding.Electrolyte, it is inner that it is placed in housing 1, infiltrates winding battery core 5.
The capacity of this high tension super capacitor is 140 ~ 190F, and voltage is 3.0V ~ 3.5V.
This high tension super capacitor, use the carbon nanomaterial being applied in the high-ratio surface of pole piece, use that can be stable when operating voltage is 3.V, higher than general at present 2.5 and 2.7V operating voltage.High voltage can make electric capacity monomer store more electric charge, thus provides higher energy density and power density.This ultracapacitor can adopt the mode of series connection to form module simultaneously, provides higher real work voltage.The raising of monomer voltage can make the amount of monomer in super capacitor module reduce, and the difficulty of combo is reduced.In addition this ultracapacitor can complete with the manufacture of current ultracapacitor production equipment, and apparatus and process is ripe, good stability.
