Description
Technical field
The present invention relates to a kind of low internal resistance pole structure of capacitor, particularly disclose a kind of low internal resistance pole structure of ultracapacitor.
Background technology
Ultracapacitor is emerging a kind of energy storage mode, compares with traditional chemical power supply (storage battery), has higher specific power and useful life, and is to belong to the non-maintaining energy-storage travelling wave tube of environmental protection.The ultracapacitor main feature is that charging rate is fast, charge efficiency is high; And charge acceptance is far above battery.Have extended cycle life; Can reach 10 years normal service time, and be the non-maintaining type product.Property at high and low temperature is good; The ultracapacitor operating temperature range is-40～60 ℃.The characteristics of ultracapacitor have determined it to be worth having important use aspect electric automobile such as bus, tourist coach, goods yard carrier or the mixed power vehicle, and use in the solar energy system field.
The high power characteristic of ultracapacitor is derived from the ultralow internal resistance of himself, and wants to produce the ultracapacitor of ultralow internal resistance, and it is necessary that good structural design, the material of good conductivity are selected.In the ultracapacitor of inorganic alkaline system, general reference hydrogen nickel-based battery or ickel-cadmium cell, what the pole material adopted is iron, although cost is low but internal resistance is higher, be unfavorable for reducing internal resistance, iron material is in corrosion region in the rated operational voltage scope simultaneously, and is influential to useful life.So it is very important finding a kind of suitable pole, and the present invention just is being based on this proposition.
Summary of the invention
The objective of the invention is to solve a prior art difficult problem, provide a kind of ultralow internal resistance simultaneously stable again pole structure, disclose a kind of low internal resistance pole structure of ultracapacitor.
The present invention is achieved in that a kind of low internal resistance pole structure, comprise pole and pad, it is characterized in that: pole is connected with pole piece, and middle process lug electric current compiles row's structural member, and electric current compiles row and is connected with cylinder, its tie point adopts molten-bath arc welding, lug one end is connected with pole piece, and the other end compiles row with electric current and is connected, and it is fan-shaped that lug is, disperse an end to be connected, compile the solder joint employing argon arc welding that row is connected with electric current with pole piece.Described pole structural member electric current compiles row's material and adopts nickel alloy, and the lug material adopts nickel.
Because the effect of pole is the electric current on the pole piece is compiled by lug and to be drawn out to the housing outside, connects load or connection in series-parallel again, so which kind of connected mode pole and lug junction adopt directly influence the capacitor internal resistance.The material of pole piece generally is a nickel at present, so ear pole material is also identical, if directly pole is used the low resistance copper product, although can reduce internal resistance, copper nickel is because the difference of fusing point causes welding than senior general or welding effect is very poor.The present invention adopts corronil to compile row as the electric current of transition, has solved Welding Problems.
Complex poles rod structure of the present invention particularly has great advantage aspect the internal resistance of reduction monomer, the raising product stability very big advantage being arranged when being composed in series high-tension assembly.
Description of drawings
Fig. 1 is the low internal resistance pole structural representation of the present invention;
Fig. 2 is an one embodiment of the invention 10000F monomer structure schematic diagram;
Fig. 3 is the end view of Fig. 2.
In the drawings: 1, cylinder; 2, housing; 3, electric current compiles row; 4, lug; 5, pole piece; 6, molten-bath arc welding solder joint; 7, argon arc welding solder joint; 8, hold-down nut; 9, sealing rubber ring.
Embodiment
With reference to the accompanying drawings 1, electric current compiles row 3 for the monel material, is shaped as rectangle, and thickness is 3～5mm, the centre position is that electric current compiles row 3 molten-bath arc welding solder joint 6 positions that are connected with pole 1, narrow groove is opened at the edge, is lug 4 positions, and each groove generally can be at 5～10 lugs 4 of argon arc welding solder joint 7 positions welding, simultaneously can open a plurality of grooves as required, for example pole piece 5 sum is 20, and each slot welding connects 5, then compiles at electric current and evenly leaves 4 grooves on the row 3 and get final product.Pole 1 cylinder processes for the copper metal, and bottom and electric current compile row's 3 welding, and middle by housing 2 process hermetic units, the upper end is screw thread or screw.
With reference to the accompanying drawings 2,3, design ultracapacitor product capacity is 10000F, and internal resistance is 1 milliohm, uses 10 pairs at electrode.The anodal sintered nickel electrode that adopts, it is active material that negative pole adopts active carbon, nickel strap is a collector, by welding with pole 1, forms cluster.Housing 2 adopts polypropylene material to add fire retardant, and electrolyte is the potassium hydroxide solution of 9mol/L.Electric current compiles row to be gone up per 5 and is welded in the groove, and through actual test, the actual internal resistance that causes of pole is less than 0.15 milliohm.
On each tie point of structure of the present invention, all comprise metal solder of the same race, it is best that welding effect reaches, and for example lug and electric current compile row's welding, and ear pole material is the nickel metal, and electric current compiles row and is monel, and its fusing point is approaching, and amalgamation is fine.Stability in the electrode system of the present invention is better, and the copper cylinder is on liquid level, and while plating nickel on surface, electric current compile row and be monel, and corrosion resistance far surpasses the copper metal, and pole has formed stable state in alkaline system.Structure of the present invention has very big using value aspect the very high ultracapacitor of power requirement.
