Embodiment

(1) summary of execution mode

Shown in Fig. 1 (a), concavity container 2 has recess 13, is formed with the portion that stores 17 that has metal level 11 in the bottom surface in the bottom of this recess 13.

Metal level 11 is made up of tungsten, can tolerate the firing temperature of concavity container 2.

On metal level 11, be formed with the collector body 18 of carbon, on this collector body 18, be fixed with as anodal electrode 6 as electric conducting material.These collector bodies 18 form with electrode 6 as follows.

After concavity container 2 is fired, supply with the conductive paste of carbon as electric conducting material to the portion of storing 17.It is because conductive paste is aqueous, therefore, becomes the reason of short circuit in order not leak towards periphery, utilizes to store the central portion that portion 17 concentrates on this conductive paste recess 13 that setting stores portion 17.

Then, conductive paste is solidified, form collector body 18 through conductive paste is heated.And when placement electrode 6 heated on conductive paste, conductive paste solidified, and forms the collector body 18 that is fixed with electrode 6.

Usually, as can except aluminium, also having carbon as the material of collector body; But, as this execution mode, after supplying with conductive paste on to metal level 11 and heating; Form collector body 18, therefore, need not pass through the dry process of aluminium being carried out vacuum evaporation etc.

Therefore, the reduction of manufacturing cost and the simplification of manufacturing process etc. can be realized, the productivity of double electric layer capacitor 1 can be improved.

In addition, under the situation of placing electrode 6 on the conductive paste, the surface tension of utilizing conductive paste is positioned at the central authorities of the portion of storing 17 with electrode 6, and therefore, the location of electrode 6 is simple, and thus, productivity improves.

The viscosity of conductive paste is approximately 400dPas, but operation property is poor, therefore, can use low boiling point solvents such as diluent to dilute.Through this dilution, viscosity can be reduced to below about 40dPas.Like this; Reduce considering operation property under the situation of viscosity of conductive paste; Have the effect of avoiding following situation: conductive paste is followed solvent and is risen along wall, under the state that rises, makes under the situation of its dry solidification, and wall is in conductivity state; Under the situation of multilayer electrode, there is risk of short-circuits property.

And, can form the tunicle of unsetting or crystalline carbonaceous through the CVD method.

For example; Can form as follows: the nickel that coating comprises as a kind of vapor grown carbon is catalyst dispersion of nano-particles solution; After making solvent seasoning; In tube furnace, be heated to more than 600 ℃ and the temperature below 1600 ℃, under reduction atmosphere gas, flow into the gas that comprises methane, acetylene or other hydrocarbons.

And at this moment, the vapor grown carbon of moulding can be the carbon of the tubulose of single or multiple lift.And then, promote the crystallization of the lining of carbonaceous through heat treated, and then, give active processing, thus, can increase specific area.At this moment, can be integrally formed electrode 6 and collector body 18, therefore, the raising of operation property.

(2) details of execution mode

(the 1st execution mode)

Constitute the electrochemical cell of the electronic unit of this execution mode with reference to description of drawings.In addition, below, as execution mode, be that example describes with the double electric layer capacitor, still, electronic unit also can be the electrochemical cell of other kinds such as nonaqueous electrolyte battery.

For example can be following battery: negative pole uses the electrode slice by binding agent (20wt%) formation of silica (50wt%), conductive auxiliary agent (40wt%) and the polyacrylic of activation through lithium metal; The anodal use by the element of lithium-manganese-oxygen has the electrode slice that the binding agent (5wt%) of active material (85wt%), conductive auxiliary agent (10wt%) and the PTFE system of the crystal structure of spinel-type constitutes, and this battery is through dividing plate that is made up of glass fiber and the LiN (SO that in PC, dissolves 1M ₂CF ₃) ₂And the electrolyte that obtains constitutes.Here, size anodal and negative pole can be long 1mm * wide 1.5mm * thick 0.2mm.

And then, except above-mentioned positive active material, can also use Li ₄Ti ₅O ₁₂, Li ₄Mn ₅O ₁₂, LiCoO ₂Deng.And,, can also use Li-Si-O, Li-Al etc. as the active material of negative pole.

And, through using the LiBF of dissolving 1M in PC ₄And the electrolyte that obtains etc. can constitute lithium ion battery.At this moment, in each active material, can use conductive auxiliary agent and binding agent in the lump.

(a) of Fig. 1 is the side sectional view of the double electric layer capacitor 1 of the 1st execution mode.Double electric layer capacitor 1 has rectangular shape, size have for example highly be below 1 [mm], vertically be about 2.5 [mm], laterally be the rectangular shape about 3.0 [mm].

Use have recess 13 concavity container 2, downside surface be formed with metal level 15 hush panel 3 (thickness is about 0.1 [mm]), wait formation double electric layer capacitor 1 as the electrode 5 of negative pole, electrode 6, dividing plate 7, jointing metal layer 8, metal level 11, collector body 18, through electrode 21, through electrode 22, terminal 10, terminal 12 and the electrolyte of enclosing in the recess 13 (not shown) as anodal.

Terminal the 10, the 12nd, the terminal that mounted on surface is used, below, establishing

terminal

10,12 1 sides is lower direction, establishing hush panel 3 one sides is last direction.

In addition, in (a) of Fig. 1,, between electrode 5, dividing plate 7, electrode 6, illustrate the gap, still, also can in recess 13, insert these parts with mode very close to each other in order to distinguish the engagement relationship of parts easily.

Concavity container 2 for example is made up of the pottery that uses aluminium oxide, fires and integrated through overlapping many ceramic sheet materials with flexibility 41～45 that are called as raw cook, thereby forms this concavity container 2.The thickness that can establish each sheet after firing is 100～300 μ m.And when becoming same thickness, managerial labour and time decreased when preparing sheet are desirable.In (a) of Fig. 1, be shown in broken lines the junction surface of sheet material 41～45.

On raw cook, be formed with recess 13 with store 17 corresponding opening portions of portion and with the corresponding hole of through hole that through

electrode

21,22 is set; Through at range upon range of these raw cooks of thickness direction and fire, form the concavity container 2 of through hole with recess 13 and through

electrode

21,22 usefulness.Here, the diameter that can establish through electrode is approximately 100 μ m.And when range upon range of raw cook, the error during with the through electrode that is absorbed in each layer formation and through electrode skew is a purpose, can implement the conductor printing of tungsten (W) system at the upper surface of each raw cook in advance.

More particularly; On

sheet material

41,42, be formed with the corresponding through hole of shape with through

electrode

21,22; On sheet material 43, be formed with the through hole corresponding with the shape of through electrode 21 and with the shape corresponding opening portion of the portion of storing 17, on sheet material 44～45, be formed with the through hole corresponding with the shape of through electrode 21 and with the shape corresponding opening portion of recess 13.

When observing from the top, recess 13 has the square-section, is formed with the portion that stores 17 of the matrix shape that is formed with metal level 11 in the bottom surface in the bottom of recess 13.

Conductor printing is carried out on surface at the sheet material corresponding with the bottom surface of the portion of storing 17 42, and concavity container 2 is fired, and forms metal level 11 thus.

Here, making the size of metal level 11 is necessary bottom line, thereby reduces cost.In addition, also can form metal level 11 in the whole bottom surface of the portion of storing 17.

For example, utilize the printing ink that has corrosion resistance and can tolerate the high-melting point metal material of firing of concavity container 2 comprise tungsten etc. to carry out silk screen printing, carry out conductor printing thus.

The fusing point of tungsten is high and be difficult to oxidation, and then, and have fitting tightly extremely of appropriateness between the ceramic surface, and after firing, also have practical resistance, therefore, be suitable for the electrode that forms as in recess 13.

But, using under the situation of tungsten as the collector body of positive pole, when with the electrolyte state of contact under when applying voltage, be dissolved in the electrolyte with electrochemical mode.

Therefore, in order to prevent this dissolving, as following explanation, need to utilize collector body 18 to coat the whole surface (being the whole parts in the concavity container 2) that contacts with electrolyte based on conductive paste.

And, through being coated with, utilizing the surface tension of self and form meniscus shape along the wall of inner side on whole surface, still, also have the effect of the central portion thickness planarization that makes aqueous cream.

Aspect electrochemistry, electronics has the tendency of the sharp keen leading section that concentrates on conductor.When electrochemical device was discharged and recharged, when electronics concentrated on the sharp keen leading section of this conductor, electric power only concentrated on around this leading section, possibly promote deterioration.

Therefore,, eliminate sharp keen position, eliminate concentrating of electronics, can expect to avoid the deterioration of electrode through being coated with cream of the present invention.

Be formed with the collector body 18 that makes after conductive paste solidifies on the metal level 11.

Metal level 11 has thickness, still, makes the thickness of metal level 11 even through conductive paste, the collector body 18 that obtains having an even surface.

Conductive paste can use the phenolic resins that will comprise material with carbon element and solvent to be processed into paste and the material that obtains.Material with carbon element adds in order to give conductivity.As material with carbon element, can use in powdered graphite, the amorphous carbon (carbon black) any one or mix and to use both.

When making solvent seasoning make phenolic resins composition polymerization (curing) through heating, form phenolic resins as binding agent, with the resinous collector body 18 of carbon as electric conductor.

Here; Generally under the situation of the collector body of negative pole; Can use multiple metals such as nickel, copper, brass, zinc, tin, gold, stainless steel, tungsten, aluminium; But, being dissolved in the electrolyte in order not make collector body, anodal collector body need use the metal that is called as plug metal (plug metal) of aluminium, titanium, niobium etc.As the collector body of positive pole, except these metal, can also use carbon, in this execution mode, use the conductive paste comprise material with carbon element.When using conductive paste, need not utilize the film of formation plug metals such as vacuum evaporation, therefore, operation is significantly simplified.

Conductive paste has mixed high graphite and these the 2 kinds of materials of the unbodied carbon black in the carbon class of crystallinity in the carbon class, and then, contain phenolic resins as main component and binding agent.This phenolic resins can use with the derivative that comprise aldehyde and phenol of formaldehyde as representative.

Store portion 17 and be formed on the bottom central of recess 13, the degree of depth that stores portion 17 is set to the thickness less than electrode 6, stores the degree than the meniscus 19 of the big conductive paste of periphery of electrode 6 that is set in interior week of portion 17.Storing portion 17, become short circuit in order to prevent conductive paste and before curing, to disperse or overflowing former thereby be provided with.

Store the retention portion performance function that is used to keep conductive paste that portion 17 forms as the

sheet material

42,43 by insulating properties.

Here, meniscus 19 is when in the portion of storing 17, storing conductive paste because surface tension and the concave surface that produces on the surface of conductive paste.

When making double electric layer capacitor 1, in the portion of storing 17, store liquid conductive paste, when placing electrode 6, electrode 6 is positioned at the central authorities of the portion of storing 17 through meniscus 19 on the surface of this conductive paste.

Then, conductive paste is solidified after, form collector body 18, and electrode 6 is fixed on the central authorities of the portion of storing 17.That is, electrode 6 is fixed on the concave surface that the surface tension owing to conductive paste forms, and therefore, can position electrode 6 easily and exactly.

Like this, in this execution mode, when the formation of positive electrode collector, do not need dry processes such as vacuum evaporation, and the location of electrode 6 is easy, therefore, can realize the reduction and the productive raising of the manufacturing cost of double electric layer capacitor 1.

The electrode active material that will be main component with the activated carbon forms sheet and cuts into rectangle; Form electrode 6 thus; For example; In natural material, can use cocoanut shell, in artificial material, can use respectively through steam, chemicals or electrical way and give the material after the activity the carbide of coal pitch, petroleum asphalt or phenolic resins.

As before the explanation, range upon range of

porose sheet material

41,42 below the recess 13 of concavity container 2, thus, the bottom surface that is formed on bottom surface and the concavity container 2 of recess 13 has the through hole of peristome.

And, in this through hole, be formed with the through electrode 22 of the cylindrical shape that metal level 11 and terminal 12 are electrically connected.

It is identical that the external diameter of through electrode 22 and the internal diameter of through hole are set at, and makes between the inwall of through electrode 22 and through hole, not produce the gap.Through electrode also is called as VIA.

The diameter of through electrode 22 is about 0.1～0.3 [mm].And, between each sheet layer, be provided with target 28 through conductor printing.Through target 28, for example, even under the situation that the range upon range of appearance not high or sheet material of the precision of through hole is squinted, also can form through electrode 22 reliably.The structure of the through electrode of stating in addition, 21 is identical.

In this through hole, making with metal dusts such as tungsten is the paste sintering of main component, perhaps injects the conductive paste of carbon etc. and makes its curing, perhaps inserts metal bar or sheet material, forms through electrode 22 thus.As metal bar, for example can use the electroconductive resin of aluminium, stainless steel, tungsten, nickel, silver, gold or carbon containing etc.Electrode 6 is electrically connected with terminal 12 via metal level 11, through electrode 22.

Being formed with the metal level that hush panel 3 and concavity container 2 are engaged in the end of the peristome of recess 13 is metal level 9 and jointing metal layer 8.

Jointing metal layer 8 is made up of the layer of the scolder (nickel, gold etc.) of metal level 9 (flash coating) top of the complete cycle of the end that is formed on peristome.Jointing metal layer 8 also is called as sealing ring sometimes, is used to guarantee the air-tightness between hush panel 3 and the concavity container 2.

Flash coating for example is made up of Kovar alloy (alloy of the ratio of Co:17, Ni:29, Fe:54), and the becket that Kovar alloy system is set in the end of concavity container 2 is fired, thereby forms flash coating.

Of the back, when the peristome at recess 13 is provided with hush panel 3 and heats, solder layer fusing and with metal level 15 weldings, recess 13 is sealed by hush panel 3.

Through at the porose sheet material 41～45 of concavity container 2 laminated, the bottom surface of end and concavity container 2 that in the sidewall that surrounds recess 13, is formed on the peristome of recess 13 has the through hole of peristome.

And, in this through hole, be formed with the through electrode 21 of the cylindrical shape that jointing metal layer 8 and terminal 10 are electrically connected.

It is identical that the external diameter of through electrode 21 and the internal diameter of through hole are set at, and between the inwall of through electrode 21 and through hole, do not produce the gap.

The material of through electrode 21 and formation method and to use that target 28 engages etc. identical with through electrode 22.

After the printing ink etc. that comprises tungsten in utilization carries out conductor printing and fires,, thereby form terminal 10,12 at its surperficial plating gold or nickel etc.And then, for antirust, can be above nickel plating metal such as plating gold or tin.

Plating comprises electrolysis plating, electroless plating etc., and, also can form through the vapor phase method of vacuum evaporation etc.

Thus, can guarantee the higher scolding tin wettability of

terminal

10,12, can at substrate surface double electric layer capacitor 1 be installed well.

In addition, in this execution mode, terminal 10,12 is set, still, also can be formed on outer lateral side portion, perhaps, can also be formed into the side continuously from outside, bottom surface in the outside, bottom surface portion of concavity container 2.

In through hole, be provided with through

electrode

21,22 backs and

form terminal

10,12.

And, when terminal 10,12 is not formed into the end of bottom of concavity container 2, utilizing oval-shaped sheet material to form simultaneously under the situation of a plurality of double electric layer capacitors 1, when cutting these double electric layer capacitors 1, can prevent peeling off of

terminal

10,12 etc.

Hush panel 3 is the metal partss that are made up of Kovar alloy etc.Therefore the coefficient of thermal expansion of Kovar alloy and pottery, under the situation about when Reflow Soldering, double electric layer capacitor 1 being heated, can be suppressed at the stress that produces between hush panel 3 and the concavity container 2 about equally.

Downside surface in hush panel 3 is formed with the metal level 15 that is formed by nickel plating, so that hush panel 3 engages with jointing metal layer 8 well.

When soldering metal level 15 on jointing metal layer 8, hush panel 3 engages with the peristome physical engagement and the electricity of recess 13.

When soldering, make its fusing through hush panel 3 being pressurizeed and heating, thereby hush panel 3 and concavity container 2 are engaged.

More specifically, can use following parallel seam welding: with suitable pressure welding roll is contacted with the edge portion of hush panel 3, its rotation is moved while switch on.Through contact resistance jointing metal layer 8 is heated, pressurize and heat.Except parallel seam welding, can also use heat welded based on laser.

Under the situation of carrying out parallel seam welding; The preferred good material of blending of selecting jointing metal layer 8 and hush panel 3; For example; Use at jointing metal layer 8 under the situation of electrolytic nickels, no electrolytic nickel, hush panel 3 uses have been implemented electrolytic nickel to Kovar alloy or have not been had electrolytic nickel and the material that obtains.

Perhaps, on the contrary, use at jointing metal layer 8 under the situation of electrolytic nickels, hush panel 3 is used Kovar alloy has been implemented no electrolytic nickel and the material that obtains.Thus, need not bonding power be brought up to and get final product more than necessary.And then, not having under the situation of electrolytic nickel, can use various reducing agents.For example can enumerate dimethylamino monoborane, ortho phosphorous acid, hydrazine, sodium borohydride etc.Here, as scolder, when the nickel fusion that plating is used, the fusing point of preferred nickel is lower.Therefore, reducing agent during plating uses ortho phosphorous acid, thus, be under the situation of " Ni:90%-96%, P:4%-10% " in the chemical composition of completed plating, compares with the situation of boracic, and fusing point is lower, so is suitable for soldering.

And, be fixed on for sealing ring on the flash coating of pottery jointing metal layer 8, also can use scolder or soldering tin materials such as gold solder, silver solder.

At the downside surface of metal level 15, the conductive adhesive through carbon containing engages the electrode 5 that is made up of electrode active material.

The material of electrode 5 is identical with electrode 6 with shape.The part 51 that contacts with electrode 5 of metal level 15 is as collector body performance function.And, the electric conductor performance function that part 52 conducts that do not contact with electrode 5 of metal level 15 engage with collector body.

Like this, electrode 5 is electrically connected with terminal 10 via metal level 15, jointing metal layer 8, through electrode 21.

Electrode

5,6 in the blank part that constitutes by recess 13 and hush panel 3 relatively, at electrode 5, be provided with between 6 and be used to prevent

electrode

5,6 because contact and the dividing plate 7 of short circuit.

As the material of dividing plate 7, for example can use the nonwoven fabrics or the glass fiber of the material formation that obtains by giving hydrophily to the surface of PPS (polyphenylene sulfide), PEEK (polyether-ether-ketone), denaturation PE EK, PTFE heat-resistant resins such as (polytetrafluoroethylene) etc.

And then, in the blank part that constitutes by recess 13 and hush panel 3, enclose electrolyte.

Electrolyte is for example by dissolving (CH in PC (propene carbonate) or SL nonaqueous solventss such as (sulfolane) ₃) (CH ₄) 3NBF ₄The solution that obtains Deng supporting salt constitutes.Like this, in this execution mode, use liquid, still, also can use the electrolyte of gel or solid, shaped as supporting salt.Though depend on encapsulating method,, use liquid flux as electrolytical situation under, preferred boiling point is more than 200 ℃.And then the preferred heat that can not apply owing to sealing rises steam pressure.Can in electrolyte, add boiling point less than 100 ℃ lower boiling solvent, still, the steam pressure under the fusing point of preferred resin at least is below the 0.2MPa-G.Injecting under the situation of electrolyte, in recess 13, inject electrolyte after, through reducing pressure separately, heat, pressurize or their combination, can make the thin portion of electrolyte osmosis to electrode.

In addition, under the electrolytical situation of using solid, do not need dividing plate 7.

And then, using under the fixing electrolytical situation, when adopting electrolyte with the discontiguous structure of collector body, collector body can not dissolve, therefore, can be with electrode 5 as positive pole, with electrode 6 as negative pole.

With terminal 10 is that negative pole, terminal 12 are that the mode of positive pole is installed the double electric layer capacitor 1 that constitutes as stated at substrate surface, for example, and can be as the memory of portable phone or the stand-by power supply of clock.

Under this situation; In portable phone; In assembling main power source battery, double electric layer capacitor 1 is charged, when changing battery or under the situation of main power voltage reduction, the electric charge that is accumulated in the double electric layer capacitor 1 is discharged; To the memory supply capability, perhaps keep the function of clock etc.

More than, utilizing with the aluminium oxide is the pottery formation concavity container 2 of main component, still, for example, also can be made up of the heat proof material of heat-resistant resin, glass, glass-ceramic etc.

Utilizing glass or glass ceramics to form under the situation of concavity container 2, through conductor printing to low-melting glass or glass ceramics implement wiring and range upon range of after, fire at low temperatures.

Utilizing resin to constitute under the situation of concavity container 2, also can insert moulding to through

electrode

21,22.

And; About through electrode 22, when the diameter that is set at sheet material 42 is bigger than the diameter of sheet material 41, even heating and making under the situation that the pressure of recess 13 rises when Reflow Soldering; This pressure also acts on through electrode 22, can prevent that through electrode 22 from coming off from concavity container 2.

Equally, about through electrode 21, the diameter that can be set at sheet material 45 is bigger than the diameter of sheet material 41～44.

(b) of Fig. 1 is the figure that is used to explain the variation of double electric layer capacitor 1.

In this example, double electric layer capacitor 1 does not have through

electrode

21,22, and the wiring of the side through being formed on concavity container 2 makes

electrode

5,6 be connected with terminal 10,12.Other structures are identical with the 1st execution mode of explanation before.

Metal level 11 penetrates into the outside of concavity container 2 along the surface of sheet material 42 from the bottom surface of the portion of storing 17, be electrically connected with the terminal 12 of the bottom surface that is formed on concavity container 2 via the side of concavity container 2.

Metal level 11 is formed on the bottom surface of the portion of storing 17 with the MIN size of necessity, still, also can be formed on whole bottom surface.In addition, make the thickness of metal level 11 even, obtain smooth collector body 18 through conductive paste.

Metal level 9 engages with jointing metal layer 8 in the upper surface of concavity container 2, and, be electrically connected with the terminal 10 of the bottom surface that is formed on concavity container 2 via the side of concavity container 2.

In the side of concavity container 2, be provided with auxiliary electrode at the upper surface of sheet material 41～44, so that the electrical connection of side is more reliable.

Like this, can constitute double electric layer capacitor 1 with the mode of not using through electrode.

(c) of Fig. 1 is the example of the collector body 20 after the upper surface setting of metal level 11 is coated with conductive paste and curing in advance.Under this situation, use conductive adhesive etc. that metal level 11 and collector body 20 and collector body 20 and electrode 6 are engaged.

Like this, also can not in the portion of storing 17, to inject conductive paste and it is solidified, but the conductive paste after solidifying in advance is set in the portion of storing 17.

In addition, collector body 20 with mode very close to each other be embedded in metal level 11 around, make electrolyte not contact with metal level 11.

Thus, can prevent metal level 11 strippings and cause quality to reduce.

(d) of Fig. 2 utilizes conductive paste to form the example of through electrode.

On sheet material 42, form the through hole that penetrates into metal level 11 from the bottom surface of the portion of storing 17, after injecting conductive paste in the portion of storing 17, conductive paste is invaded through hole and is solidified, and forms through electrode 61.

And,, can eliminate the bubble that is involved in conductive paste in the position of through electrode 61 through after injecting conductive paste, reducing pressure.

Collector body 18 is integrally formed with through electrode 61, and therefore, electrode 6 is electrically connected with terminal 12 via collector body 18, through electrode 61, metal level 11.

And in this example, jointing metal layer 8 is electrically connected through through electrode 21 with terminal 10.

Fig. 2 (e) is following example: utilize through electrode 61 to carry out being electrically connected of collector body 18 and metal level 11, and, utilize 9 pairs of jointing metal layers of metal level 8 and terminal 10 to be electrically connected.

(f) of Fig. 3 is not at recess 13 making end differences and directly as the example that stores portion 17.In this example, be electrically connected with metal level 11 through 61 pairs of collector bodies 18 of through electrode.

(g) of Fig. 3 is the example that forms collector body 18 in the part of the bottom of the portion of storing 17.Like this, even do not form collector body 18, also can make electrode 6 performance functions in the whole bottom surface of the portion of storing 17.

In this example, do not make end differences and as storing portion 17 at recess 13, and, be electrically connected with metal level 11 through 61 pairs of collector bodies 18 of through electrode.

Each figure of Fig. 4 is the figure that is used to explain the formation method of collector body 18.

At first, shown in Fig. 4 (a), prepare to be formed with the concavity container 2 of jointing metal layer 8, through

electrode

21,22, metal level 11,

terminal

10,12.

Then, the conductive paste of the portion of storing 17 being supplied with as collector body 18.The quantity delivered of conductive paste is set to the whole bottom surface that is paved with the portion of storing 17 and the degree that forms meniscus 19.

(b) of Fig. 4 be before the portion of storing 17 is supplied with conductive pastes from above observe the figure of concavity container 2.

As shown in the figure, the bottom in the portion of storing 17, metal level 11 forms circle.In addition, the shape of metal level 11 also can be a shape arbitrarily such as rectangle.

(c) of Fig. 4 observes the figure to the situation after the concavity container 2 supply conductive pastes from the top.Central authorities at concavity container 2 store the conductive paste as collector body 18.

Then, as shown in Figure 5, on as the liquid level of the conductive paste of collector body 18, place electrode 6.So, make electrode 6 be positioned at the central portion of the portion of storing 17 through the meniscus 19 of conductive paste.

Then, be heated to 180 [℃] about temperature after, conductive paste solidifies and becomes collector body 18, electrode 6 is fixed on the central portion of the portion of storing 17.

Though diagram not,, on electrode 6, place dividing plate 7 then, supply with electrolyte, and then after utilizing the peristome of 3 pairs of recesses 13 of hush panel that electrode 5 is installed to seal soldering, double electric layer capacitor 1 is accomplished.

In addition, repeatedly carry out the portion of storing 17 is supplied with conductive pastes and makes the operation (promptly be divided into repeatedly and be coated with) of its curing, thus, can collector body 18 be formed stratiform.

Under this situation, carry out repeatedly the portion of storing 17 supplied with that conductive pastes are heating and curing and then the operation that conductive paste is heating and curing is supplied with in its top, below the superiors till one deck.

Then, when forming the superiors, supply with conductive paste, after on its liquid level electrode 6 being set, heat, the conductive paste of the superiors is solidified as the superiors.Like this, collector body 18 forms stratiform.

And, under the situation of the thinner thickness of conductive paste,, therefore, cause that the lower electric power of degree concentrates because the difference in thickness and the distribution of conductive paste produce deviation in resistance.

Therefore, when the coating conductive paste, it is important being coated with the uniform thickness more than about 50 μ m.After coating, heat, thus, the polymerization of the host of the hardener that comprises in the cream and the catalyst of curing owing to chemical reaction, carbon contacts with each other, and forms the current collector layer 18 of the grid with electron conduction.

At this moment, be purpose with the viscosity that reduces conductive paste, add organic solvent sometimes, produce bubble during this solvent gasification, forming diameter sometimes is the intercommunicating pore of the path about a few μ m.

Perhaps, the gas componant in the atmosphere gas that when the coating conductive paste, is involved in sometimes also can form the intercommunicating pore of above-mentioned path.Via under this intercommunicating pore and the situation that metal level 11 contacts, the metal of metal level 11 is from this intercommunicating pore stripping sometimes at electrolyte, is reduced on the surface of activated carbon and becomes metal.

For fear of the dissolving of this metal with separate out, behind the coating conductive paste, reduce pressure, thereby eliminate bubble, thus, the effect of the generation of the said intercommunicating pore that can be inhibited.

And, even be divided into repeatedly with the coating of the uniform thickness more than about 50 μ m conductive paste, the effect of the generation of the said intercommunicating pore that also can be inhibited.At this moment, be divided at least being coated with more than 2 times and get final product, be more preferably the coating of carrying out more than 3 times.

Through the execution mode of above explanation, can access following effect.

(1) can utilize material with carbon element to form anodal collector body 18.

(2) conductive paste is solidified and form collector body 18, therefore, do not need the dry process of vacuum evaporation etc.
