Abstract
A capacitor in an implantable medical device is provided. The capacitor having an anode, a cathode including a conductive coating, and an electrolyte disposed and in contact between the anode and the cathode. The conductive coating is composed of a chemisorbed conductive layer that is interposed between a metal substrate and a layer including a mix of activated carbon with a metal-oxide and electrolyte disposed and in contact between the anode and the cathode.
