摘要： A capacitor assembly configured to effectively dissipate heat when exposed to a high ripple current is provided. The assembly includes a plurality of capacitor elements, each including an anode body and lead, a dielectric layer overlying the anode body, and a solid electrolyte. A metal cylindrical housing having a lid and base, where the lid has a diameter in an −x direction and the metal cylindrical housing has a height in a −z direction, defines an interior cavity within which the plurality of capacitor elements are arranged about a central axis running along the −z direction. The ratio of the diameter to the height of the base ranges from about 1.5 to about 20. Further, the metal cylindrical housing is hermetically sealed.

摘要： The present invention relates to a method for forming a capacitor having carbon or metal electrodes and an electrolyte which is also a source of electropolymerisable anions. Applying a sufficiently positive voltage, a thin dielectric layer forms at the positive electrode, enabling the use of cell voltages higher than 3.5 V. The construction and characteristics of capacitors with 5, 6.3, and 10 V of cell voltages, having reduced graphene oxide electrodes and an ionic liquid electrolyte, are shown. Further, a method of forming a capacitor, including the steps of: (a) providing a first electrode; (b) providing a first electrolyte including an anionic compound, wherein said compound includes at least one cyano group or at least one nitrile group; (c) electropolymerising said anionic compound in order to form a dielectric layer on at least part of the first electrode; (d) forming a capacitor including the electrode of step (c), a second electrode and a second electrolyte, which is the same or different to the first electrolyte, is claimed. In a further aspect of the invention, there is provided an electronic device including a capacitor, a transistor or an electrode produced by means of a method as defined above. It is believed that a number of dielectric compounds produced by the method as defined above are new compounds not previously isolated. Accordingly, polytetracyanoborate, polycyani, or polytricyanomethanide.

摘要： There is provided a solid electrolytic capacitor which can increase an electrostatic capacitance and reduce ESR characteristics, and a method of manufacturing the solid electrolytic capacitor. The solid electrolytic capacitor has: a dielectric oxide film formed on a surface of an anode body having fine pores; a cathode body opposing to the anode body; and conductive polymer layers formed inside the fine pores and including amines and water-soluble self-doped conductive polymers having sulfonic acid groups. The self-doped conductive polymers are held in a good state inside fine pores such as etching pits, so that the electrostatic capacitance increases and ESR characteristics are reduced.

摘要： A capacitor whose electrical properties can be stable under a variety of different conditions is provided. The solid electrolyte of the capacitor is formed from a combination of an in situ polymerized conductive polymer and a hydroxy-functional nonionic polymer. One benefit of such an in situ polymerized conductive polymer is that it does not require the use of polymeric counterions (e.g., polystyrenesulfonic anion) to compensate for charge, as with conventional particle dispersions, which tend to result in ionic polarization and instable electrical properties, particularly at the low temperatures noted above. Further, it is believed that hydroxy-functional nonionic polymers can improve the degree of contact between the polymer and the surface of the internal dielectric, which unexpectedly increases the capacitance performance and reduces ESR.

The composite dielectric layer overlays the metal layer. The polymer dielectric layer includes a nitrogen-containing polymer and overlays the metal oxide dielectric layer.

摘要： A solid electrolytic capacitor that includes an anode body, a dielectric overlying the anode body, a solid electrolyte that contains one or more conductive polymers and overlies the dielectric, and an external coating that overlies the solid electrolyte, is provided. The external coating includes at least one carbonaceous layer and at least one metal layer. In addition to the aforementioned layers, the external coating can also include at least one conductive polymer layer that can be disposed between the carbonaceous and metal layers. Among other things, such a conductive polymer layer can reduce the likelihood that the carbonaceous layer will delaminate from the solid electrolyte during use. Further, the notched geometry of the anode body itself is selected to minimize the risk of delamination of the external coating layers from the anode body. This combination of characteristics can increase the mechanical robustness of the part and improve its electrical performance.
