20080232037 | SOLID ELECTROLYTIC CAPACITOR CONTAINING A CONDUCTIVE POLYMER - A method for forming an electrolytic capacitor is disclosed. The method includes forming a conductive polymer coating by polymerizing a monomer in the presence of less than a stoichiometric amount of an oxidative polymerization catalyst. The present inventor has found that the use of less than the stoichiometric amount of the oxidative polymerization catalyst per mole of monomer can slow the polymerization of the monomer, creating oligomers that are shorter in length than if fully polymerized into a polymer. Without wishing to be bound by theory, it is believed that these shorter oligomers provide better penetration into the porous anode. Thus, the resulting conductive polymer layer can be more intimately positioned with respect to the anode. As a result, the formed capacitor can exhibit better performance. | 09-25-2008 |

The capacitor also contains an anode lead that is electrically connected to the anode body. Contrary to conventional capacitors in which the lead is welded or connected using a layer of seed particles, a refractory metal paste (e.g., tantalum paste) is employed in the present invention to electrically connect the anode lead to the anode body. The use of such a refractory metal paste allows the anode lead to be sinter bonded to a surface of the anode body after it is pressed. In this manner, a strong and reliable connection may be achieved without substantially decreasing the surface area of the lead that is available for connection to a termination.

20120039019 | Solid Electrolytic Capacitor Assembly - A capacitor assembly that includes a solid electrolytic capacitor element containing an anode body, a dielectric overlying the anode, and a solid electrolyte (e.g., conductive polymer) overlying the dielectric is provided. The anode body is in electrical contact with an anode termination and the solid electrolyte is in electrical contact with a cathode termination. The capacitor element and terminations are encapsulated within a resinous material so that at least a portion of the terminations remain exposed. In addition to enhancing mechanical robustness, the resinous encapsulating material acts in some capacity as a barrier to moisture and oxygen during use, which could otherwise reduce the conductivity of the solid electrolyte and increase ESR. To even further protect the capacitor element, especially at high temperatures, the encapsulated capacitor element is also enclosed and hermetically sealed within a ceramic housing in the presence of an inert gas. It is believed that the ceramic housing is capable of limiting the amount of oxygen and moisture supplied to the conductive polymer of the capacitor. In this manner, the solid electrolyte is less likely to undergo a reaction in high temperature environments, thus increasing the thermal stability of the capacitor assembly. | 02-16-2012 |
20120075775 | Solid Electrolytic Capacitor with Improved Anode Termination - A capacitor containing a solid electrolytic capacitor element that includes an anode, dielectric, and solid electrolyte is provided.

The resulting “folded” configuration of the anode termination increases the total thickness of the upstanding portion and its associated slot, which thereby enhances the degree of mechanical support and stability that the termination provides to the anode lead. This is particularly beneficial for thicker anode leads, such as those having a height and/or width of about 100 micrometers or more, in some embodiments about 200 micrometers or more, and in some embodiments, from about 250 to about 1000 micrometers. | 03-29-2012 |

The coating is formed from a colloidal particle dispersion. The particles of the dispersion contain at least two different polymer components—i.e., a conductive polymer and a latex polymer. One benefit of such a coating is that the presence of the latex polymer can help mechanically stabilize the capacitor during encapsulation due to its relatively soft nature. This helps limit delamination of the solid electrolyte and any other damage that may otherwise occur during formation of the capacitor. Furthermore, the latex polymer can also enhance the ability of the particles to be dispersed in an aqueous medium, which is desirable in various applications. | 09-13-2012 |
