    Abstract: A technique for forming a cathode of a wet electrolytic capacitor is provided. The cathode contains a metal substrate having a roughened surface and a conductive coating that contains a substituted polythiophene. The degree of surface contact between the conductive coating and the roughened surface is enhanced in the present invention by selectively controlling the manner in which the conductive coating is formed. More particularly, the conductive coating is formed by applying a precursor solution to the roughened surface that includes both a precursor thiophene monomer and an oxidative catalyst. Contrary to techniques in which either the monomer or catalyst is applied separately and initially contacts the metal surface, the presence of the monomer and catalyst within the same solution allows polymer chains to grow immediately adjacent to the surface of the metal substrate and within the pits.

    Abstract: A solid electrolytic capacitor that contains an anode body formed from an electrically conductive powder and a dielectric coating located over and/or within the anode body is provided. The present inventors have discovered a technique that is believed to substantially improve the uniformity and consistency of the manganese oxide layer. This is accomplished, in part, through the use of a dispersant in the precursor solution that helps minimize the likelihood that the manganese oxide precursor will form droplets upon contacting the surface of the dielectric. Instead, the precursor solution can be better dispersed so that the resulting manganese oxide has a “film-like” configuration and coats at least a portion of the anode in a substantially uniform manner. This improves the quality of the resulting oxide as well as its surface coverage, and thereby enhances the electrical performance of the capacitor.

Advantageously, embodiments of a three-dimensional capacitor drastically reduce the space footprint that is required in a circuit to accommodate the capacitor, when compared to current capacitor designs.

  • Publication number: 20110277287
    Abstract: A cell electrode plate is constituted by band-like core member made of metal foil and a plurality of sheets of electrode active material applied discontinuously on and longitudinally of at least one of upper and lower surfaces of the core member, the mutually adjacent sheets of the electrode active material having mutually different end positions widthwise of the core member. Thereby, an increase in worn amount of surfaces of press rolls is prevented when the cell electrode plate is pressed by a roll press machine with the press rolls so as to prolong the service life of the press rolls. Thus, the number and/or amount of grinding the press rolls is reduced to reduce the roll maintenance cost and enhance production efficiency.

  • Publication number: 20110267738
    Abstract: The present invention relates to a multi-layer ceramic capacitor printed simultaneously with internal electrode and external electrode by employing an inkjet printing. A method for manufacturing the multi-layer ceramic capacitor comprising first external electrode, dielectric, internal electrode and second external electrode prints simultaneously the first external electrode; the internal electrode which is connected with the first external electrode and formed at an invaginated portion of the dielectric invaginated to allow one side to be opened at one portion; and the second external electrode which is formed integrally with the internal electrode by employing an inkjet printing. According to the present invention, a method for manufacturing the multi-layer ceramic capacitor resolves contact problems by printing integrally the internal electrode and the external electrode and reduces the manufacturing process.

  • Patent number: 8042264
    Abstract: The invention describes rolled electroactive polymer devices. The invention also describes employment of these devices in a wide array of applications and methods for their fabrication. A rolled electroactive polymer device converts between electrical and mechanical energy; and includes a rolled electroactive polymer and at least two electrodes to provide the mechanical/electrical energy conversion. Prestrain is typically applied to the polymer. In one embodiment, a rolled electroactive polymer device employs a mechanism, such as a spring, that provides a force to prestrain the polymer. Since prestrain improves mechanical/electrical energy conversion for many electroactive polymers, the mechanism thus improves performance of the rolled electroactive polymer device.

  • Publication number: 20110239424
    Abstract: A capacitor element is obtained by chemically converting an anode body comprising a niobium or niobium alloy in an electrolyte solution, which is obtained by dissolving an oxygen supply agent such as hydrogen peroxide, a freezing point depressant such as ethylene glycol, and an electrolyte such as phosphoric acid in water, at a solution temperature lower than the freezing point of a solution having the composition of the electrolyte solution excluding the freezing point depressant, for forming a dielectric layer in the surface of the anode body or repairing a dielectric layer formed in the surface of the anode body. An electrolytic capacitor is obtained by forming a cathode on the dielectric layer of the capacitor element, electrically connecting the anode body and the cathode respectively to external terminals, and then sealing them.
