Description

[Technical Field]

[0001] This invention relates to an electrical or electronic device, a method for manufacturing the aforementioned electrical or electronic device, and an apparatus having the aforementioned electrical or electronic device. The invention claims priority to Japanese Patent Application No. 2021-179842 filed on November 2, 2021, and Japanese Patent Application No. 2022-089542 filed on June 1, 2022, the contents of which are incorporated herein by reference. [Previous Technology]

[0002] Solid electrolytic capacitors are increasingly used as electrical or electronic devices in mobile devices such as cell phones, laptops, and portable game consoles, as well as in automotive equipment such as car navigation systems and engine control circuits.

[0003] Solid electrolytic capacitors have an anode layer, a dielectric layer, a solid electrolyte layer, and a cathode layer. Moreover, it is known that solid electrolytic capacitors having a solid electrolyte layer containing a conductive polymer compound have excellent electrical characteristics, which reduces the equivalent series resistance (ESR) value.

[0004] As the aforementioned conductive polymer compound, polyvinyl dioxythiophene (hereinafter, sometimes referred to as "PEDOT / PSS") doped with polystyrene sulfonate is known (e.g., Patent Document 1). [Prior Art Documents]

[0005] [Patent Documents] Patent Document 1: International Publication No. 2007 / 091656 [Summary of the Invention]

[0006] [The problem the invention aims to solve]

[0007] However, PEDOT / PSS has low heat resistance. In high-temperature environments exceeding 100°C, its conductivity will decrease significantly due to dedoping and decomposition of the main chain backbone. Therefore, it is difficult to use it for applications exposed to high temperatures, such as engine control circuits in automobiles.

[0008] Furthermore, PSS has high hygroscopicity. Moreover, water is typically used when forming a solid electrolyte layer containing PEDOT / PSS. Therefore, the solid electrolyte layer containing PEDOT / PSS is inherently prone to moisture content, which easily generates strong sulfonic acid. Consequently, if the solid electrolyte layer containing PEDOT / PSS is laminated with a dielectric layer, the sulfonic acid generated from the solid electrolyte layer will cause corrosion of the dielectric layer, easily leading to an increase in ESR value and making it difficult to stably maintain electrical properties. In other words, the electrical properties deteriorate significantly due to moisture, and poor moisture resistance becomes a problem.

[0009] Therefore, an object of the present invention is to provide an electrical or electronic device with excellent heat resistance and moisture resistance. Another object of the present invention is to provide a method for manufacturing the aforementioned electrical or electronic device. Another object of the present invention is to provide an electrical or electronic device incorporating the aforementioned electrical or electronic device. [Means for Solving the Problem]

[0010] The inventors have conducted intensive research to solve the aforementioned problems and have discovered that conductor materials formed by doping conjugated polymer compounds with anions selected from nitrogen anions, boron anions, phosphorus anions, and antimony anions are not easily dedoped even at high temperatures because these anions are stably accommodated in the interstices of the crystal structure of the conjugated polymer compound. Compared to PEDOT / PSS, these conductor materials have lower hygroscopicity, reducing the amount of water used in the manufacturing process. By reducing the amount of water used in the manufacturing process, the moisture content at the conductor material's origin can be suppressed. Electrical or electronic devices having a laminated structure of a conductor material layer and an electrode layer with the aforementioned conductor material as the main component can maintain conductivity even at high temperatures by suppressing dedoping, and can suppress the moisture content of the conductor material layer even in high humidity environments, thereby suppressing corrosion of easily corroded layers such as electrode layers and dielectric layers caused by moisture in the conductor material layer. The present invention is based on these insights.

[0096] The reaction temperature of reaction (III) is, for example, about -100 to 10°C. The reaction time is, for example, about 0.5 to 5 hours.

[0097] Reaction (IV) is a cross-coupling reaction of the compound shown in formula (e) and the compound shown in formula (c). Reaction (IV) is carried out using the same method as reaction (II), except that the compound shown in formula (e) is used instead of the compound shown in formula (b). (Polymer compound (2))

[0098] The polymer compound (2) has a repeating unit as shown in formula (2) below. The benzene ring in formula (2) below may have one or more substituents. Examples of the aforementioned substituents include halogen atoms, hydrocarbon groups having 1 to 5 carbon atoms (e.g., methyl), etc. (Anion)

[0099] The aforementioned anion (or dopant anion) is selected from at least one of nitrogen anion, boron anion, phosphorus anion and antimony anion.

[0100] Among the aforementioned anions, nitrogen anions or boron anions are preferred in terms of their excellent corrosion inhibition effect on easily corroded layers such as electrode layers and dielectric layers. Furthermore, nitrogen anions and boron anions, after releasing their ionic bonds with countercations, stably reside in the interstitial spaces of the crystal structure of conjugated polymer compounds, thereby improving the crystallinity of the conjugated polymer compounds. Therefore, they are also preferred in terms of their excellent doping inhibition effect.

[0101] The aforementioned nitrogen anion is represented, for example, by the following formula (a). (In the formula, Ra11 to Ra12 represent electron-attracting groups in the same or different ways. Ra11 and Ra12 may bond to each other and form a ring together with the adjacent nitrogen atom.)

[0102] Examples of the aforementioned electron-attracting groups include: nitro, cyano, (C1-5) acetyl, carboxyl, (C1-5) alkoxycarbonyl, halo(C1-5)alkyl, sulfonyl, (C1-5)alkylsulfonyl, halosulfonyl, halo(C1-5)alkylsulfonyl, etc.

[0103] Ra11 and Ra12 are preferably halosulfonyl or haloalkylsulfonyl. In addition, Ra11 and Ra12 can be bonded to each other to form sulfonyl-haloalkyl-sulfonyl.

[0104] The aforementioned halosulfonyl group includes, for example, fluorosulfonyl, chlorosulfonyl, etc.

[0105] The aforementioned haloalkylsulfonyl groups include, for example, fluoroalkylsulfonyl groups (such as fluoromethylsulfonyl, trifluoroethylsulfonyl, trifluoropropylsulfonyl, pentafluoropropylsulfonyl, etc., fluoroC1-5 alkylsulfonyl groups; trifluoromethylsulfonyl, pentafluoroethylsulfonyl, pentafluoropropylsulfonyl, nonafluorobutylsulfonyl, etc., perfluoroC1-5 alkylsulfonyl groups), chloroalkylsulfonyl groups (such as chloromethylsulfonyl, etc., chloroC1-5 alkylsulfonyl groups), and other haloC1-5 alkylsulfonyl groups.

[0106] The halogenated alkyl group in the sulfonyl-halogenated alkyl-sulfonyl group formed by the mutual bonding of Ra11 and Ra12 is, for example, fluoroalkyl (e.g., tetrafluoroalkyl ethyl, hexafluoropropane-1,3-diyl, octafluorobutane-1,4-diyl, etc., perfluoroC1-5 alkyl groups), chloroalkyl (e.g., perchloroC1-5 alkyl groups, etc.), etc., halogenated C1-5 alkyl groups.

[0107] As the aforementioned nitrogen anion, the anion shown in formula (a-1) below is particularly preferred in terms of low hygroscopicity. Using this anion, a conductor material with particularly low hygroscopicity can be formed, thereby significantly suppressing corrosion of easily corroded layers such as electrode layers and dielectric layers caused by moisture content in the conductor material. (In the formula, Ra1 to Ra2 represent halogen atoms or haloalkyl groups, either identically or differently. Ra1 and Ra2 can be bonded together to form haloalkyl groups.)

[0108] The aforementioned haloalkyl groups are, for example, fluoroalkyl groups (such as fluoromethyl, trifluoroethyl, trifluoropropyl, pentafluoropropyl and other fluoroC1-5 alkyl groups; trifluoromethyl, pentafluoroethyl, pentafluoropropyl, nonafluorobutyl and other perfluoroC1-5 alkyl groups), chloroalkyl groups (such as chloromethyl and other chloroC1-5 alkyl groups), and other haloC1-5 alkyl groups.

[0109] The aforementioned halogenated alkyl groups are, for example, fluoroalkyl groups (such as tetrafluoroalkyl ethyl, hexafluoropropane-1,3-diyl, octafluorobutane-1,4-diyl, etc., perfluoroC1-5 alkyl groups), chloroalkyl groups (such as perchloroC1-5 alkyl groups, etc.), and other halogenated C1-5 alkyl groups.

[0110] The aforementioned boron anion is preferably, for example, the anion shown in formula (a-2) below. Using the aforementioned anion allows the formation of a conductive material with particularly low hygroscopicity, thereby significantly suppressing corrosion of easily corroded layers such as the electrode layer and dielectric layer caused by moisture content in the conductive material. (In the formula, Ra3 to Ra7 represent halogen atoms or haloalkyl groups, either identically or differently.) [First Electrode Layer]

[0111] When the electrical or electronic device is a solid electrolytic capacitor, the first electrode layer is an anode layer, preferably a layer containing a rectifying metal. The anode layer is formed, for example, from a rectifying metal foil or a sintered body containing rectifying metal particles. Examples of the aforementioned rectifying metal include aluminum, tantalum, niobium, titanium, zirconium, hafnium, tungsten, and alloys containing them.

[0112] The surface of the aforementioned layer containing the rectifying metal can also be enlarged by etching or other surface-expanding processes. [Dielectric layer]

[0113] When the electrical or electronic device is a solid-state electrolytic capacitor, it is preferable to include a dielectric layer between the anode layer and the conductor material layer. The dielectric layer is, for example, a layer containing an oxide of a rectifying metal. When the first electrode layer is a layer containing a rectifying metal, the dielectric layer can be formed by anodizing the first electrode layer. For example, when aluminum foil is used as the first electrode layer, anodizing the first electrode layer can form a dielectric layer containing aluminum oxide on the surface of the first electrode layer. [Second Electrode Layer]

[0114] When the electrical or electronic device is a solid electrolytic capacitor, the second electrode layer is a cathode layer. The cathode layer is preferably a layer containing a metal such as silver, for example, it can be formed by coating a resin composition containing silver particles and drying it to form a silver-containing resin film. [Manufacturing method of electrical or electronic device]

[0115] The aforementioned electrical or electronic device may be manufactured by doping a dopant into a conjugated polymer compound.

[0116] Methods of doping a dopant into a conjugated polymer compound include methods using a dry process and methods using a wet process.

[0117] As an example of the aforementioned dry process method, a method of attaching a dopant to the surface of a conjugated polymer compound (such as a film, sheet, or coating containing a conjugated polymer compound) by means of vacuum evaporation or sputtering is provided.

[0118] As an example of the aforementioned wet process method, the following method is used: impregnating a conjugated polymer compound [or a layer containing a conjugated polymer compound (e.g., a film, sheet, coating, etc. containing a conjugated polymer compound)] in a dopant solution formed by dissolving and / or dispersing the dopant in a solvent, or coating the aforementioned dopant solution onto the surface of a conjugated polymer compound ([or a layer containing a conjugated polymer compound (e.g., a film, sheet, coating, etc. containing a conjugated polymer compound)], and then drying it. After drying, annealing treatment may be performed as needed.

[0119] The aforementioned manufacturing method for electrical or electronic devices using a wet process includes, for example, the following steps: Step 1: A solution containing a conjugated polymer compound is coated onto the surface of a substrate and dried to form a layer containing a conjugated polymer compound. Step 2: A dopant solution containing a salt comprising anion selected from nitrogen anion, boron anion, phosphorus anion, and antimony anion and a countercation is coated onto the layer containing the conjugated polymer compound and dried to obtain a conductor material layer containing a conductor material composed of a conjugated polymer compound doped with the aforementioned anions. (Step 1)

[0120] This step involves coating a solution containing a conjugated polymer (hereinafter sometimes referred to as "polymer solution") onto the surface of a substrate and drying it to form a layer (or a film containing a conjugated polymer) containing a conjugated polymer.

[0121] There are no particular limitations on the method for forming a layer containing a conjugated polymer compound. For example, it can be formed by coating a polymer compound solution onto a substrate or immersing a substrate in a polymer compound solution, and then allowing the solvent to evaporate. The thickness of the aforementioned coating is, for example, about 10 to 500 nm. The aforementioned coating can be thickened by repeated coating as needed.

[0122] There are no particular limitations on the aforementioned substrate. When manufacturing a solid electrolytic capacitor for the aforementioned electrical or electronic device, it is preferable to use the first electrode layer / dielectric layer laminate (specifically, an aluminum / alumina laminate) as the substrate.

[0123] The polymer solution contains at least the above-mentioned conjugated polymer and a solvent, for example, the conjugated polymer can be dissolved in a solvent to produce it.

[0124] The polymer solution may contain only one type of conjugated polymer, or may contain two or more types in combination.

[0125] Preferably, the solvent is a solvent with excellent solubility for conjugated polymers, such as: aromatic hydrocarbons such as benzene, toluene, xylene, ethylbenzene, trifluorotoluene, chlorobenzene, anisole, benzonitrile, nitrobenzene, and ethyl benzoate. They can be used alone or in combination of two or more.

[0126] The polymer compound solution can suppress the moisture content, thereby suppressing the moisture content of the conductor material layer, which is preferable in that it can suppress corrosion of easily corroded layers such as electrode layers and dielectric layers caused by moisture in the conductor material layer. The aforementioned moisture content is, for example, 2% by weight or less, preferably 1% by weight or less, more preferably 0.8% by weight or less, further preferably 0.7% by weight or less, further preferably 0.6% by weight or less, especially preferably 0.5% by weight or less, most preferably 0.45% by weight or less, and particularly preferably 0.4% by weight or less.

[0127] When the above-mentioned polymer compound (1) or polymer compound (2) is used as a conjugated polymer compound, the polymer compound (1) and (2) have low hygroscopicity and excellent solubility in organic solvents, thus significantly reducing the water content in the polymer compound solution.

[0128] When the surface of the substrate (e.g., the surface of the dielectric layer of the first electrode layer / dielectric laminate) is porous, or when the surface of the substrate is uneven, a heat treatment can be applied to soften the layer containing the conjugated polymer compound after its formation, thereby allowing the layer containing the conjugated polymer compound to better follow the surface of the substrate and increase the contact surface area. (Step 2)

[0129] This step is as follows: a dopant solution containing a salt of anion selected from nitrogen anion, boron anion, phosphorus anion and antimony anion and counter cation is coated onto the layer containing the conjugated polymer compound obtained in step 1 and dried to obtain a conductor material layer containing a conductor material composed of the aforementioned anions doped in the conjugated polymer compound.

[0130] The aforementioned dopant solution is a composition formed by dissolving and / or dispersing the dopant in a solvent. In addition, the dopant may be contained in a single form or in combination of two or more forms.

[0131] Examples of the aforementioned solvents include ester solvents such as methyl acetate, ethyl acetate, isopropyl acetate, and butyl acetate; and nitrile solvents such as acetonitrile, propionitrile, and benzonitrile. They can be used alone or in combination of two or more.

[0132] As a method for coating a layer containing a conjugated polymer compound with a dopant solution, for example, a method of immersing the layer containing the conjugated polymer compound in a dopant solution. After coating with the dopant solution and drying it, annealing may also be performed as needed.

[0133] The moisture content of the aforementioned dopant solution is preferably 1% by weight or less, more preferably 0.8% by weight or less, further preferably 0.7% by weight or less, further preferably 0.6% by weight or less, especially preferably 0.5% by weight or less, most preferably 0.45% by weight or less, and particularly preferably 0.4% by weight or less. If the moisture content of the aforementioned dopant solution is set within the aforementioned range, the moisture content of the conductor material layer can be suppressed, thereby suppressing corrosion of easily corroded layers such as electrode layers and dielectric layers caused by moisture in the conductor material layer.

[0134] If the dopant described later is used as the dopant, the water content in the dopant solution can be suppressed to the aforementioned range because the dopant described later has excellent solubility in the aforementioned solvent.

[0135] When a dopant is incorporated into a conjugated polymer, the counter cations derived from the salt contained in the dopant function as oxidants, pulling electrons out of the conjugated polymer. This generates holes in the conjugated polymer that act as charge carriers, thus exhibiting conductivity. Furthermore, the valence of the counter cations decreases after electron extraction, and they are excluded from the conjugated polymer system.

[0136] If the valence of the counter cation decreases, the anion derived from the salt contained in the dopant will release its ionic bond with the counter cation. Then, the aforementioned anion will be stably housed in the interstitial spaces of the crystal structure of the conjugated polymer compound. In this way, the conjugated polymer compound can gain conductivity while improving crystallinity and suppressing dedoping.

[0137] The aforementioned method for manufacturing electrical or electronic devices may also include other steps as needed, such as the step of forming a second electrode layer on the surface of the conductor material layer after step 2.

[0138] When the aforementioned method for manufacturing an electrical or electronic device is a method for manufacturing a solid electrolytic capacitor, a step may be set before step 1 to obtain a first electrode layer / dielectric layer by anodic oxidation of a rectifier metal foil to generate an oxide film on the surface, and a solution containing a conjugated polymer compound may be coated on the surface of the obtained first electrode layer / dielectric layer.

[0139] The oxidation of rectifier metal foil can be carried out in the presence of oxygen, ozone or molecules that supply oxygen atoms, or in the presence of oxygen, ozone or molecules that supply oxygen atoms and light, plasma, etc.

[0140] When the aforementioned method for manufacturing an electrical or electronic device is a method for manufacturing a solid-state electrolytic capacitor, a step of first forming a graphite layer on the surface of a conductor material layer may also be provided, and a step of then forming a second electrode layer may be provided. (Dopant)

[0141] The dopant (e.g., a P-type dopant) contains a salt comprising an anion selected from nitrogen anion, boron anion, phosphorus anion and antimony anion and a counter cation.

[0142] The aforementioned anions are as described in the above (anions) section.

[0143] As for the aforementioned counter cation, there are no particular restrictions as long as it is a cation that acts by pulling out electrons from a self-conjugated polymeric compound. Examples include metal cations such as lithium cations (especially alkali metal cations) and free radical cations as shown in formula (b) below.

[0144] The free radical cation shown in formula (b) below is preferred in terms of excellent oxidizing power, easy extraction of electrons from conjugated polymers, and ability to increase the doping amount of anions. It is especially preferred to be a compound shown in formula (b) below, and a compound in which at least one of Rb1, Rb2, and Rb3 is a group shown in formula (r) below. [In formula (b), Rb1 to Rb3 represent the same or different monovalent aromatic groups or groups shown in formula (r) below.] [n represents the valence of the free radical cation, and is equal to the number of nitrogen atoms in formula (b) (n atoms)] (In formula (r), Ar 1, Ar 2, and Ar 3 represent divalent aromatic groups, and Ar 4, Ar 5, Ar 6, and Ar 7 represent monovalent aromatic groups that may have substituents as shown in formula (sb). s and t represent integers greater than 0.

The wavy lines in the formula are bonded to the monovalent aromatic groups in formula (r))

[0145] s, t, u, and v represent integers greater than or equal to 0, for example, 0 to 5, preferably 0 to 3, and even more preferably 0 to 2. If the values ​​of s, t, u, and v increase, there is a tendency to improve the doping efficiency of conjugated polymer compounds.

[0146] When s, t, u, and v are all integers of 2 or more, there are multiple groups shown in parentheses, and these groups may be the same or different.

[0147] The aforementioned monovalent aromatic group is a group obtained by removing one hydrogen atom from the structural formula of an aromatic compound [more specifically, a group obtained by removing one hydrogen atom bonded to the carbon atom constituting the aromatic compound (or carbon atom or heteroatom when the aromatic compound is an aromatic heterocycle).

[0148] In addition, the aforementioned divalent aromatic group is a group obtained by removing two hydrogen atoms from the structural formula of an aromatic compound [more specifically, a group obtained by removing two hydrogen atoms bonded to the carbon atom constituting the aromatic compound (or carbon atom or heteroatom when the aromatic compound is an aromatic heterocycle).

[0149] The aforementioned aromatic compounds include aromatic hydrocarbons and aromatic heterocycles.

[0150] The aforementioned aromatic hydrocarbons include, for example, aromatic hydrocarbon rings with 6 to 14 carbon atoms such as benzene and naphthalene, and structures formed by two or more of the aforementioned aromatic hydrocarbon rings bonded by single bonds or linking groups.

[0151] As the aforementioned linking group, examples include: C1-5 alkyl groups, carbonyl groups (-CO-), ether groups (-O-), thioether groups (-S-), ester groups (-COO-), amide groups (-CONH-), carbonate groups (-OCOO-), etc.

[0153] Examples of the aforementioned aromatic heterocycles include: a monocyclic aromatic heterocycle having carbon atoms and at least one heteroatom (e.g., oxygen atom, sulfur atom, nitrogen atom, phosphorus atom, etc.) as constituent atoms of the ring, and a fused ring formed by condensing one or more aromatic hydrocarbon rings on the aforementioned monocyclic aromatic heterocycle. Specifically, examples include: pyrrole, furan, thiophene, phosphacyclopentadiene, pyrazole, imidazole, azole, isazole, thiazole, indole, benzofuran, benzothiophene, isoindole, isobenzofuran, benzophosphacyclopentadiene, benzimidazole, benzozazole, benzothiazole, benzoisothiazole, indazole, benzoisothiazole, benzotriazole, purine, pyridine, phosphabenzene, pyrimidine, pyridine, tri-, 1,2,4,5-tetra-, 1,2,3,4-tetra-, 1,2,3,5-tetra-, hexa-, quinoline, isoquinoline, quinoline, quinazoline, porphyrin, pteridine, phthalide, acridine, 4aH-phenanthridine, carbazole, etc.

[0154] The aforementioned monovalent aromatic group and divalent aromatic group may have substituents. Examples of such substituents include: halogen atoms, C1-5 alkyl groups, side oxygen groups, hydroxyl groups, substituted oxygen groups (e.g., C1-5 alkoxy groups, C1-5 acetoxy groups, etc.), carboxyl groups, substituted oxycarbonyl groups (e.g., C1-5 alkoxycarbonyl groups), substituted or unsubstituted aminomethyl groups, cyano groups, nitro groups, amino groups, substituted amino groups (e.g., mono- or di-C1-5 alkylamino groups, mono- or di-C1-5 acetylamino groups), etc. Among the aforementioned substituents, halogen atoms are preferred, and bromine atoms are particularly preferred.

[0155] In addition to the aforementioned substituents, the monovalent aromatic group may also have groups represented by, for example, the group shown in the following formula (sb-1). [In the formula, Ar 14 and Ar 15 represent the same or different monovalent aromatic group. The wavy lines in the formula are bonded to the carbon atom constituting the aromatic compound (when the aromatic compound is an aromatic heterocycle, it is a carbon atom or a heteroatom)]

[0156] As one of the monovalent aromatic groups in Ar 14 and Ar 15 in the above formula, the example is the same as the one mentioned above.

[0157] The dopant may also contain components other than the salt containing the aforementioned anions and countercations, such as oxidants. The oxidant works by pulling electrons out of the conjugated polymer compound, thereby increasing the doping amount of the anions.

[0158] In particular, when the dopant contains a salt containing the aforementioned anion and a metal cation such as lithium cation (especially an alkali metal cation), it is preferable that the dopant contains an oxidant together with the aforementioned salt.

[0159] Examples of the aforementioned oxidants include, for example, α,β-unsaturated nitrile compounds with conjugated double bond structures, NOPF 6, ferric chloride (FeCl 3), and halogen monomers (e.g., iodine I 2, bromine Br 2, chlorine Cl 2). They can be used alone or in combination of two or more.

(In the above formulas, s1 to s5 represent the number of cyano groups bonded to the ring structure, and are all or different integers of 1 or more. Substituents other than cyano groups (e.g., halogen atoms, etc.) may also be bonded to the ring structure shown in the formulas.)

[0161] The total number of cyano groups in the aforementioned compound is one or more, preferably two or more. In addition, the upper limit of the total number of cyano groups is, for example, four.

[0162] Examples of the aforementioned α,β-unsaturated nitrile compounds having a conjugated double bond structure include: tetrafluorotetracyanoquinone dimethane, 2,3-dichloro-5,6-dicyano-1,4-benzoquinone, 2,3-diiodo-5,6-dicyanoquinone, 2,2',4,4'-tetracyanobiphenol, 2,4,7-tricyano-9-enanthrene, tetracyanoquinone dimethane, 2,5-difluoro-7,7,8,8-tetracyanoquinone dimethane, 2-fluoro-7,7,8,8-tetracyanoquinone dimethane, etc.

[0163] The amount of the aforementioned oxidant used is, for example, about 0.5 to 5 mol relative to 1 mol of the salt containing the aforementioned anion and countercation. (Method for manufacturing the salt containing the aforementioned anion and countercation)

[0164] For example, a salt containing an anion of formula (a-1) or (a-2) and a free radical cation of formula (b) can be prepared by reacting an ionic compound containing an anion of formula (a-1) or (a-2) with an amine compound corresponding to a free radical cation of formula (b) in the presence of an oxidant.

[0165] The aforementioned ionic compounds and the aforementioned amine compounds may be used alone or in combination of two or more.

Examples of such solvents include: nitrile solvents such as acetonitrile, propionitrile, and benzonitrile; water; alcohol solvents such as methanol; amine solvents such as N,N-dimethylformamide and N,N-dimethylacetamide; ether solvents such as diethyl ether, THF, and dialkyl; and ester solvents such as ethyl acetate. They can be used individually or in combination of two or more.

[0173] As for the environment of the aforementioned reaction, there are no particular limitations as long as it does not hinder the reaction. For example, it can be any of the following: an air environment, a nitrogen environment, an argon environment, etc.

[0174] The temperature of the aforementioned reaction is, for example, around -70 to 60°C. The reaction time is, for example, around 0.5 to 5 hours.

[0175] After the reaction is completed, the resulting reaction products can be separated and purified by separation methods such as filtration, concentration, distillation, extraction, crystallization, adsorption, recrystallization, column chromatography, or combinations thereof.

[0193] Example 1 (Formation of the first electrode layer / dielectric layer)

[0194] Porous aluminum is used as the anode conductor containing a rectifying metal. Anodizing the aluminum is performed to form an oxide film on its surface, thereby obtaining an aluminum / alumina laminate. (Conductor material layer formation - 1; Layer formation containing conjugated polymer compounds)

[0195] Then, the aluminum / alumina laminate was immersed in a toluene solution (water content: 0.3 wt%) of the polymer compound (1-1-2a) obtained in Preparation Example 4 and then lifted out. Afterwards, it was dried at 80°C to cure, thereby forming an aluminum / alumina / polymer compound thin film laminate. (Conductor material layer formation - 2; doping)

[0196] Then, the aluminum / alumina / polymer thin film laminate was immersed in a butyl acetate solution (water content: 0.3 wt%) of the dopant (1) obtained in Preparation Example 1, dried at 80°C, and then cleaned with butyl acetate and dried at 80°C. This formed an aluminum / alumina / conductor material laminate. (Formation of the second electrode layer)

[0197] A graphite layer and a silver-containing resin layer are sequentially formed on the conductor material layer of the obtained multilayer. Thereby, a solid electrolytic capacitor (1) [aluminum / alumina / conductor material layer / graphite layer / silver-containing resin layer] is obtained.

[0198] At 25°C, a voltage ranging from -9V to 9V was applied to the obtained solid electrolytic capacitor (1) using a DC power supply, and the current value was measured after 60 seconds at each voltage to confirm that it functioned as a capacitor. (Low ESR assessment)

[0199] For the obtained solid electrolytic capacitor (1), the ESR value was measured using an LCR meter at 25°C and 100kHz. Furthermore, the ESR value was normalized to a unit area (1 cm²) for the entire cathode area. The results are shown in Table 1. (Heat Resistance Assessment)

[0200] For solid electrolytic capacitors subjected to a heat resistance test at 150°C for 2000 hours, the ESR value was measured using the same method as in the (low ESR assessment), and the rate of increase in ESR value from 25°C was calculated. The results are shown in Table 1. Example 2

The solid electrolytic capacitor (2) was obtained in the same manner as in Example 1, and the low ESR and heat resistance were evaluated in the same manner as in Example 1.

At this time, 2,3,5,6-tetrafluorotetracyanoquinone dimethane becomes a free radical anion, which dissolves in butyl acetate along with the Li cation and is discharged from the polymer compound system. Example 3

[0203] In the (conductor material layer formation-2) step, the acetonitrile solution (water content: 0.3 wt%) of the dopant (3) obtained in Preparation Example 3 was used instead of the butyl acetate solution of the dopant (1). The solid electrolytic capacitor (3) was obtained in the same manner as in Example 1, and the low ESR and heat resistance were evaluated in the same way as in Example 1.

[0204] If the aforementioned dopant (3) is used, 3-dichloro-5,6-dicyanobenzoquinone functions as an oxidizing agent for polymers, and the TFSI anion is introduced into the polymer as a counter anion against the oxidized polymer. At this time, 2,3-dichloro-5,6-dicyanobenzoquinone becomes a free radical anion, dissolves in acetonitrile along with the Li cation, and is discharged from the polymer system. Comparative Example 1

(Moisture resistance assessment)

[0209] For the obtained solid electrolytic capacitor (5), the ESR value was measured using an LCR meter at a frequency of 120 kHz and 25°C. Furthermore, the ESR value was normalized to a unit area (1 cm²) for the entire cathode area. Then, the obtained solid electrolytic capacitor (5) was subjected to a moisture resistance test by being left to stand at 25°C and 85% RH for 3 days. For the solid electrolytic capacitor after the moisture resistance test, the ESR value was measured using an LCR meter at a frequency of 120 kHz and 25°C. Furthermore, the rate of increase in ESR during the moisture resistance test was calculated. The results are shown in Table 2. Example 5
