Abstract
The utility model discloses a bipolar pole super capacitor, wherein the positive pole piece and the negative pole piece of the inner cavity of the shell are respectively connected with the positive pole column and the negative pole column outside the shell through bus bars and pole lugs, the improvement is that the positive pole column and the negative pole column are provided with two groups which are respectively arranged on the upper side surface and the lower side surface of the shell, and two pole lugs are welded on the bus bars of each positive pole piece and each negative pole piece; the bus bar is of an annular structure, the lugs are welded on the upper side and the lower side of the annular bus bar, preferably in the diagonal position of the bus bar, and the pole is composed of a stud and an articulated nut. The utility model discloses can shorten the distance that the electron flowed on the mass flow body, bipolar post has the reposition of redundant personnel effect to greatly reduced condenser internal resistance makes its heavy current discharge performance obviously improve, is particularly useful for high-power output's electrical power generating system.
Description
Technical field
The utility model relates to a kind of ultracapacitor, belongs to the power-type technical field of electronic components.
Background technology
Ultracapacitor is the novel power-type electronic devices and components that occur along with the breakthrough of material science in recent years.It has filled up specific energy and specific power blank between ordinary capacitor and the battery, has high extremely thousands of farads capacitance, also has the characteristics safe and reliable, that the scope of application is wide simultaneously, is to improve and the applicable breakthrough components and parts of solution electric energy dynamic property.Ultracapacitor still is a kind of environmental type product, and energy-saving and environmental protection can not have a negative impact to user and environment, are a kind of power supply products of health.Ultracapacitor has huge using value and market potential at aspects such as automobile (particularly electric automobile, fuel combination automobile and exceptional load vehicle), electric power, railway, communication, national defence, consumption electronic products, by countries in the world institute extensive concern.
Ultracapacitor has excellent heavy-current discharge performance with respect to general chemistry power supply such as lead-acid battery, lithium battery, has very high specific power.But existing ultracapacitor is owing to the restriction of structure and technology, and its internal resistance is often bigger than normal, has reduced the product power output, influences the practical effect of product.Ultracapacitor on the market all adopts the one pole rod structure at present, because little electric current on pole piece surface at first is pooled on the collector, flow to the lug place by busbar again, again by pole output, the electric current of the monopole ear carrying in the one pole rod structure is very big, the distance that the while electronics moves is far away, the resistance of collector itself is bigger, will cause the ultracapacitor operating voltage on the low side like this, during heavy-current discharge, the heating phenomenon is serious, and security reliability is relatively poor.When the pole piece area increased, this effect was particularly evident.
The utility model content
The technical problems to be solved in the utility model is that the weak point that overcomes existing ultracapacitor provides a kind of internal resistance little, good heavy current, and combined and instant, bipolar post ultracapacitor that security reliability is high.
The technical solution of the utility model is: bipolar post ultracapacitor comprises positive and negative plate, positive and negative pole, housing critical piece, positive and negative plate is connected with positive and negative pole respectively with lug by busbar, improvements are that described positive and negative pole has two groups, place the upper side and the downside of housing respectively, be welded with two lugs on the busbar of every positive and negative plate.
Above-mentioned busbar is a loop configuration, be welded on positive and negative plate around, lug is welded on the upper and lower both sides of ring busbar; Preferred plan is the diagonal positions that lug is welded on busbar; Described positive and negative pole is for having externally threaded double-screw bolt or being made of double-screw bolt and movable joint nut.
Owing to adopt above technical scheme, the busbar of annular compiles electric current on the collector rapidly, flows to two lug places of pole piece respectively, and the utilance of little electric current improves greatly, and electric current can be emitted by moment; Because electrode plates has two electric current outbound courses, and the distance that electronics flows through on the collector shortens, the shunting action of bipolar post makes the overall internal resistance of capacitor reduce simultaneously, and heavy-current discharge performance is improved.
This ultracapacitor pole adopts the movable joint structure simultaneously, does not need extra intercell connector to connect, and does not have the resistance influence of intercell connector; Directly be fastenedly connected by the movable joint nut between the pole, combined and instant, the bonding strength of whole group ultracapacitor is higher, and it is very low to connect internal resistance, helps improving the high-power output performance of bank of super capacitors, improves security reliability.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Referring to accompanying drawing, the inner chamber of housing 1 is provided with electrode plates 2 and is clipped in barrier film 3 between the adjacent pole piece, and injection electrolyte, in the pole piece just, the alternate setting of negative plate, be welded with nickel plated steel strip around the pole piece and form ring busbar 4, just, on the busbar of negative plate, following both sides diagonal positions is welded with a pair of lug 8 respectively, the upper side of housing and downside are just respectively being established one group, negative terminal, wherein the upper side pole is made of double-screw bolt 5 and movable joint nut 6, the downside pole is formed by double-screw bolt, on, down just, negative terminal respectively with just, on on the negative plate, following lug welds mutually, and the housing upper side also is provided with safety valve 7.Contrast after tested, the internal resistance of this bipolar post ultracapacitor descends 30～40% than the one pole post ultracapacitor internal resistance of same capability, and high-rate performance improves a lot.
