    Abstract: A cellulose solution obtained by dissolving cellulose in an amine oxide solvent is formed in a film form, and the resulting cellulose solution is immersed in water or a poor solvent of the amine oxide solvent, so as to coagulate and regenerate the cellulose. The regenerated cellulose is washed with water to remove the amine oxide solvent, and then dried, thereby obtaining a cellulose film that is thin, uniform, and dense and has few impurities. An aluminum electrolytic capacitor, which has been down-sized and/or capacity enlarged, can be constructed by interleaving the obtained cellulose film as a separator between an anode aluminum foil and a cathode aluminum foil and winding them into a capacitor element, immersing the capacitor element in liquid electrolyte so as to impregnate it with the electrolyte, placing it in a case, and then sealing it closed and aging it.

    Abstract: A capacitor has a positive electrode, a negative electrode, and a solid electrolyte layer arranged between the electrode layers. At least one of the electrode layers of this capacitor has an Al porous body, and an electrode body held in this Al porous body to polarize the electrolyte. The oxygen content in the surface of the Al porous body is 3.1% by mass or less. The matter that the oxygen content in the surface of the Al porous body is 3.1% by mass or less is equal to the matter that a high-resistance oxide film is hardly formed on the surface of the Al porous body. Thus, this Al porous body makes it possible to make the current collector area of the electrode layer large so that the capacitor can be improved in capacity.

    Abstract: A wet electrolytic capacitor that contains an anode formed from an anodically oxidized sintered porous body and a fluidic working electrolyte is provided. The casing contains a metal substrate coated an electrochemically-active material. Through a unique and controlled combination of features relating to the capacitor configuration and sealing assembly, the present inventor has discovered that good electrical properties (e.g., ESR stability) can be achieved at relatively high temperatures. One unique feature of the wet electrolytic capacitor that can help achieve such good ESR stability is the presence of a dielectric layer on the metal substrate of the cathode within a controlled thickness range. In other embodiments, a sealing assembly may be employed that contains a hermetic seal (e.g., glass-to-metal seal) and an elastomeric barrier seal formed from a high-temperature elastomeric material.

  • Patent number: 8810996
    Abstract: An electrical component includes an inkjet-printed graphene electrode. Graphene oxide flakes are deposited on a substrate in a graphene oxide ink using an inkjet printer. The deposited graphene oxide is thermally reduced to graphene. The electrical properties of the electrode are comparable to those of electrodes made using activated carbon, carbon nanotubes or graphene made by other methods. The electrical properties of the graphene electrodes may be tailored by adding nanoparticles of other materials to the ink to serve as conductivity enhancers, spacers, or to confer pseudocapacitance. Inkjet-printing can be used to make graphene electrodes of a desired thickness in preselected patterns. Inkjet printing can be used to make highly-transparent graphene electrodes. Inkjet-printed graphene electrodes may be used to fabricate double-layer capacitors that store energy by nanoscale charge separation at the electrode-electrolyte interface (i.e., “supercapacitors”).

A sintered article in which a solid body is at least partially embedded includes an opening. The solid body extends across the opening so that the solid body can deform within the opening. The opening in the solid body prevents distortion of the sintered body from a planar configuration during sintering, even when the green body is relatively thin.

The conductive coating contains an alkyl-substituted poly(3,4-ethylenedioxythiophene) having a certain structure. Such polymers can result in a higher degree of capacitance than many conventional types of coating materials. Further, because the polymers are generally semi-crystalline or amorphous, they can dissipate and/or absorb the heat associated with the high voltage. The degree of surface contact between the conductive coating and the surface of the metal substrate may also be enhanced in the present invention by selectively controlling the manner in which the conductive coating is formed.

  • Patent number: 8462483
    Abstract: The invention relates to the field of electrical engineering, in particular to multilayer film electrodes for electrolytic capacitors. The proposed multilayer anode is implemented as a substrate with a developed surface on which are sequentially arrayed a conforming layer of a valve metal, which is connected by a heterojunction formed by nanoparticles of the substrate metal and of the valve metal, which are geometrically closed between each other, and an oxide coating. The substrate is connected to the film base through a nanocomposite barrier layer, which comprises a differentiated mixture of the materials being joined, whose content varies relative to each other,[so that] together they amount to 100%, where the working surface is formed in practice by the substrate metal. What is novel is that a metal with a hardness 2-4 times greater than that of the valve metal, preferably titanium, is used as the substrate material, and the pores of the valve-metal layer are limited in size to the range 1-104 nm.

  • Patent number: 8451586
    Abstract: A wet electrolytic capacitor that contains an anode and a fluid electrolyte that are positioned within a casing is provided. The capacitor also contains a sealing assembly that employs a bushing having opposing inwardly facing, tapered surfaces between which an orifice is defined. To help inhibit leakage from the orifice, a liquid sealing member is also employed that contains a protrusion having outwardly facing, tapered surfaces that are configured to mate with the inwardly facing surfaces of the bushing. At least one outwardly facing surface of the sealing member is tapered at an angle greater than a respective inwardly facing surface of the bushing.

  • Patent number: 8427811
    Abstract: An electrical double-layer capacitor electrode with excellent capacitance characteristics is obtained together with a manufacturing method therefor. Paper-molded sheet 2 of carbon nanotubes is integrated with etched foil 1 constituting a collector, by means of bumps and indentations 1a formed on the surface of etched foil 1 to prepare an electrical double-layer capacitor electrode. Alternatively, carbon nanotubes 4 grown around core catalyst particles on substrate 3 are integrated with etched foil 1 by means of bumps and indentations 1a formed on the surface of etched foil 1 to prepare an electrical double-layer capacitor electrode. To manufacture these electrodes, this carbon nanotube sheet 2 or substrate 3 with carbon nanotubes grown thereon is laid over bumps and indentations 1a on the surface of etched foil 1, and the sheet or substrate and the foil are pressed under 0.01 to 100 t/cm2 of pressure to integrate the carbon nanotubes with the etched foil.
