The anode and metal casing are of a size such that the anode occupies a substantial portion of the volume of the interior space. More particularly, the anode typically occupies about 70 vol. % or more, in some embodiments about 75 vol. % or more, in some embodiments from about 80 vol. % to about 98 vol. %, and in some embodiments, from about 85 vol. % to 95 vol. % of the interior space. Among other things, the use of an anode that occupies such a large portion of the interior space enhances volumetric efficiency and other electrical properties of the resulting capacitor.

摘要： A solid electrolytic capacitor containing a capacitor element that includes an anode, dielectric layer, and solid electrolyte is provided. The anode is formed from a plurality (e.g., two or more) of separate components, which allows the properties of each component (e.g., density, quality, etc.) to be more readily controlled during manufacturing. The components are electrically connected using a refractory metal paste (e.g., tantalum paste) that sinter bonds to the components to form a strong and reliable connection. The ability to reliably bond together separate components enables the use of a wide degree of possible cross-sectional profiles for each individual component. For example, the components may posses a relatively complex profile that contains one or more indentations and/or projections for increasing surface area. Despite the complex profile, the components may be readily connected to each other in accordance with the present invention to form the anode.

摘要： A solid electrolytic capacitor that contains a capacitor element that includes an anode body, dielectric layer, and solid electrolyte is provided. The capacitor also contains an anode lead that is electrically connected to the anode body by a refractory metal paste (e.g., tantalum paste). 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. Furthermore, because the lead is not embedded within the anode body, the capacitor may be configured so that little, if any, portion of the lead extends beyond the anode body. This may result in a highly volumetrically efficient capacitor with excellent electrical properties.
