Title: HERMETICALLY SEALED WET ELECTROLYTIC CAPACITOR
Abstract:
A hermetically sealed wet electrolytic capacitor includes a hermetically sealed case, a cathode, an anode, and an insulator between the anode and the cathode to provide electrical insulation between the anode and the cathode. An electrolytic solution is disposed within the case. A first terminal is electrically connected to the anode and a second terminal is electrically connected to the cathode. The hermetically sealed wet electrolytic capacitor is adapted to deliver at least 80 percent of store energy between the first and the second terminals. The cathode comprises a metal substrate having an alloy layer formed with a noble metal and a noble metal/base metal electrode element layer electrochemically deposited thereon. The electrolytic solution has a conductivity between 10 and 60 mS/cm. The capacitor may be used in an implantable device. An implantable device comprising a battery, a processor and a capacitor is build. Further, a method for manufacturing a capacitor is disclosed.
