Abstract
Various embodiments of a battery and an implantable medical device that includes such battery are disclosed. The battery includes a cathode and an anode. The cathode includes a current collector, active material disposed on the current collector, and a cathode tab that extends from the current collector. A cathode spacer is electrically connected to the cathode tab. Further, the anode includes a current collector, active material disposed on the current collector, and an anode tab extending from the current collector. An anode spacer is electrically connected to the anode tab. At least one of the cathode spacer or the anode spacer includes niobium.
