  • Patent number: 8760852
    Abstract: A capacitor containing a solid electrolytic capacitor element having a porous anode body and an anode lead assembly is provided. At least one wire of the lead assembly is electrically connected to the anode body for connection to an anode termination. The lead assembly contains first and second lead wires embedded within the anode body and extending therefrom in a longitudinal direction. The first and second wires are bonded/fused together during sintering of the anode body (i.e., “sinter bonded”). The bond may be metallurgical, covalent, electrostatic, etc. Sinter bonding of the wires reduces the path length and resistance for current flow within the anode body, thus reducing ESR. This is particularly useful for anode bodies formed from powders of a high specific charge, which tend to shrink away from the wires after sintering. The sinter bonded wires also result in a lead assembly that is more robust and mechanically stable.

  • Patent number: 8717740
    Abstract: An electrolytic capacitor in which a capacitor element can be fixed firmly into a metal case without having adverse effects on the electrical characteristics of the electrolytic capacitor. An anode foil provided with an anode internal terminal and a cathode foil provided with a cathode internal terminal are wound or laminated through a separator to produce a capacitor element. The capacitor element is then contained in a metal case together with a driving electrolyte, and then the side surface of the metal case is caulked to press and fix the capacitor element, thus producing an electrolytic capacitor. The electrolytic capacitor is characterized in that a tape material is wound by a plurality of turns around the outer circumference of the capacitor element between the capacitor element and the caulking of the metal case such that a total thickness of the tape material is so large as to relax deformation of the capacitor element when the side surface of the metal case is caulked.

  • Patent number: 8675346
    Abstract: A mesoporous, nanocrystalline, metal oxide construct particularly suited for capacitive energy storage that has an architecture with short diffusion path lengths and large surface areas and a method for production are provided. Energy density is substantially increased without compromising the capacitive charge storage kinetics and electrode demonstrates long term cycling stability. Charge storage devices with electrodes using the construct can use three different charge storage mechanisms immersed in an electrolyte: (1) cations can be stored in a thin double layer at the electrode/electrolyte interface (non-faradaic mechanism); (2) cations can interact with the bulk of an electroactive material which then undergoes a redox reaction or phase change, as in conventional batteries (faradaic mechanism); or (3) cations can electrochemically adsorb onto the surface of a material through charge transfer processes (faradaic mechanism).
