Description

201250741 VI. Description of the Invention The present invention relates to a method of manufacturing a capacitor, a capacitor obtained by the method, the use of the capacitor, the use of the circuit and the dispersion. Commercially available capacitors typically consist of a porous metal electrode, a metal oxide layer present on the metal surface, a conductive material (usually a solid introduced into the porous structure), and an external electrode ("c〇ntacting") ( For example, silver layer) & other electrical contacts and packages. A commonly used electrolytic f-capacitor is a neo-electrode capacitor having an anode electrode made of a valve metal group, and a uniform dielectric of a five-oxide one button has been formed on the group by anodization (also referred to as "f_ing"). Floor. The liquid or solid electrolyte forms the cathode of the capacitor. Aluminum capacitors are also often used. The anode electrode is made of valve metal aluminum, which is formed by anodizing to form a uniform dielectric insulating oxide dielectric layer. Here, the liquid electrolyte or solid electrolyte also forms the cathode of the capacitor. Aluminum electric grid is most commonly designed as a wound capacitor or a stacked capacitor. The π conjugated polymer is particularly suitable for use as a solid electrolyte in the above capacitors due to its high electrical conductivity. The π co-consumption polymer is also known as a conductive polymer or a synthetic metal. It is becoming increasingly important economically because it has advantages over metals in terms of processability, quality, and selectivity properties through chemical modification. It is known that examples of τ co-polymers are polypyrrole, polythiophene, polyaniline, polyphenylene, polyphenylene and poly(p-phenylene vinylene), a particularly important and technically useful polybenzazole. It is poly(3,4.ethylenedioxy porphin) (pED〇T) because its oxidized form shows extremely high conductivity. 5 201250741 Coating a telluride layer with a conductive polymer based electrolyte can be done in a number of ways. For example, ΕΡ-Α-0 340 512 is described from 3,4-extended ethylenedioxy. The phenanthrene manufactures a solid electrolyte and its use in an electrolytic capacitor. As indicated in this publication, 3,4-extended ethylenedioxythiophene is polymerized in situ on the oxide layer. As described, for example, in ΕΡ-Α-0 899 757, the oxide layer must typically be formed after deposition of the solid electrolyte to achieve a lower residual current. For this purpose, the capacitor is immersed in the electrolyte and exposed to a voltage that does not exceed the anode treatment of the oxide layer. However, the use of in-situ polymerization to produce solid electrolyte electrical sites is especially a matter of complexity. Therefore, the polymerization process involving the soaking, poly-and washing process steps each time typically takes several hours. May be an explosive or toxic solvent. Another disadvantage of making the in-situ side of a solid electrolyte capacitor is the anion of the oxidant or possibly other relative ions that act as a conductive polymer. However, these anions are not bonded to the polymerization # with sufficient stability due to their small size. This can cause diffusion of the relative ions and thus cause an increase in the equivalent series resistance (ESR) of the capacitor, especially at the high operating temperature T of the capacitor. Instead of synthesizing the relative ions in the 4-primary & polymerization, it does not produce a layer of conductive gates that are sufficiently conductive, and therefore; produces a sufficiently low ESR value. Therefore, in the state of the art, it has been developed based on the manufacture of capacitors.

Alternative Method for Solid-State Electrolytic Electrolyte Electrolyte 1 For example, DM 2005 043828 describes a method for producing a solid electrolyte in a capacitor > a slurry containing a bifurcation of the already polymerized thiophene (for example, State of the art 6 201250741 Known PEDOT/PSS dispersions are applied to the oxide layer and then the dispersant is removed by evaporation. However, the solid electrolyte obtained from such dispersions is characterized by improved parameters, specifically improved capacitance and equivalent series resistance. A method for improving the equivalent series resistance of a solid electrolyte obtained using a PEDOT/PSS dispersion is described in Jp 2〇1〇_12965ι, in which a solid obtained using a PED0T/PSS dispersion is used in an ingot-wound electric grid. The electrolyte is additionally impregnated with a solution containing a conductive monomer and an oxidizing agent to cause chemical polymerization of the monomer in the solid electrolyte layer. This method of improving the equivalent series resistance is also relatively costly because it requires additional processing steps. The object of the present invention is to overcome the disadvantages of the state of the art in the field of capacitors, in particular in the case of solid electrolyte capacitors, and in particular in capacitors, in particular wound capacitors, which are known from the state of the art. In particular, it is an object of the present invention to provide a method of fabricating a capacitor, particularly a wound capacitor, by which a capacitor exhibiting as low an equivalent series resistance as possible and a capacitance as high as possible can be fabricated. This improvement in capacitance, series resistance and capacitance should be achieved using technically shortest possible methods and, in particular, without additional processing steps. The achievement of the above objectives is facilitated by a method of manufacturing a capacitor, in particular an electrolytic capacitor, comprising the following process steps:

Introducing a conductive polymer, a dispersant, and a dispersion having the following general formula 7 201250741 (i) into at least a portion of the anode body:

Ar-XY (1), wherein Y represents a Cl_Cls alkyl group having at least one hydroxyl group, a C^-Cu alkyl decanoic acid or a polyalkyleneoxy group having a terminal hydroxyl group; and X is selected from the group consisting of ruthenium, O-Ci^R2, CR a linking group of ^R^O, NR^CR1!^, CRiRiNRiCOO, and CONR3, wherein R2 and R3 each represent a hydrogen atom or a Ci_CiQ alkyl group;

Ar represents an optionally substituted aromatic group selected from the group consisting of phenyl and naphthyl, wherein the substituent of the aromatic group may be, for example, a dentate atom, a hydroxyl group, a carboxyl group or an alkyl group, and other _χ_γ groups; The dispersant is at least partially removed to form a capacitor body. In process step a) of the process of the invention, an electrode body is first prepared from an electrode material, wherein a dielectric at least partially covers the surface of the electrode material to form an anode body. In principle, the electrode body can be produced by pressing and sintering a valve metal powder to obtain a main porous body. At the same time, a contact wire preferably made of a valve metal (e.g., a button) is pressed into the electrode body. The electrode body is then coated with a dielectric, for example via an electrochemical oxidation reaction. Alternatively, the dielectric can be coated with an electrochemical oxidation reaction to obtain an anode flute having a porous region. In the wound capacitor, the anode foil and the cathode foil having the porous regions forming the electrode body are separated by a separator and wound. 201250741 Valve metal includes B e,

In the case where a voltage is applied, a large current, which may damage the oxide layer, an alloy, or a compound of such a metal with other elements, may occur. The most well-known representative valve metal is "B" and a compound having electrical properties similar to a valve metal is a metal-conducting compound which can be oxidized and whose oxide layer has the above properties. For example, NbO has a metal Conductivity, but generally not considered a valve metal. However, the oxidized NbO layer has the typical properties of a valve metal oxide layer, so alloys or compounds of NbO or Nb0 with other elements are similar to base metals. Typical examples of compounds having electrical properties are electrode materials of ruthenium and aluminum and their electrode materials based on ruthenium or iridium oxide. Aluminum is particularly preferred as the electrode material. To manufacture an electrode body which usually has a porous region, the valve metal can be For example, sintering in powder form to obtain a generally porous electrode body or imprinting a porous structure on a metal body. The latter can be carried out, for example, by etching a foil. For the sake of clarity, the body having a porous domain is hereinafter referred to as " Porous. Thus, for example, an electrode body having a porous region is also referred to as a porous electrode body. In one aspect, the porous body can be penetrated by a plurality of channels, and thus is sponge-like. This is often the case when a capacitor is used to make a capacitor. In addition, it is possible that in the construction only the surface has pores and the area under the surface pores is solid. This is often observed if a capacitor is made of aluminum. 201250741 A generally porous electrode body manufactured in this manner is then oxidized by applying a voltage, for example, in a suitable electrolyte such as tartaric acid or an aqueous solution of ammonium adipate to form a dielectric. The magnitude of this formation voltage (f〇rming v〇itage) depends on the thickness of the oxide layer to be achieved or the subsequent use voltage of the capacitor. Preferably, the formation voltage is in the range of 1 V to 2, 〇〇〇 V. In a specific embodiment of the capacitor of the present invention, the capacitor is an aluminum capacitor', and particularly preferably a wound capacitor. In the process step b) of the process of the invention, a dispersion comprising a conductive polymer and a dispersant, preferably a conductive polymer particle and a dispersant is introduced into the porous region of the anode body* using known methods such as impregnation, dipping Crush, pour, / smear, injection, spray, knife coating, brushing or printing (eg ink jet printing 'screen printing or tamp〇n printing'), the dispersion is introduced into the porous area. This introduction is preferably accomplished by impregnating the anode body provided in process step a) into the dispersion to cause it to become impregnated with the dispersion. Immersion in the dispersant or impregnation with the dispersant is preferably carried out over a period of from leap seconds to 120 minutes, particularly preferably in the range of from 1 second to 6 minutes, and preferably in the range of from jo to 15 minutes. The introduction of the dispersion into the anode body can be facilitated, for example, by overpressure or underpressure, vibration, ultrasonic or heating. The introduction of the dispersion in the anode body can be directly achieved or the use of a binder (for example, a decane' such as an organofunctional decane or a hydrolyzate thereof, for example, a 3'-glycidyl propyl-oxyl oxime, a 3-aminopropyl group Ethoxylated ruthenium, 夂P-propyl methoxy dioxetane, 3-methyl propyl methoxy propyl trimethoxy ethoxylate trimethoxy shixi or octyl triethoxy shi Burn) and / or a 10 201250741 or a variety of other functional layers to achieve. The introduction preferably results in at least partial coating of the surface of the cavity rather than covering the hole with a surface. Thus, the particles present in the dispersion not only form a layer covering the opening of the pores but also cover at least a portion, and generally all, of the surface regions of the pores as a layer of dispersed liquid particles.

Substituted on the group R. In this case, the positive charge of the polythiophene backbone may be partially or completely saturated by an anionic group which is optionally present on the matrix R. In general, the polystyrene can be cationic, neutral or even anionic in such cases. However, in the case of the present invention, it is regarded as a cationic polythiophene because the positive charge on the primary bond of the polyphene is the determining factor f.
