Abstract
A battery comprises a battery case forming a substantially sealed enclosure and an electrode stack within the enclosure. The electrode stack includes a first set of electrode elements and a second set of electrode elements. The electrode elements in the second set alternate with the electrode elements in the first set within the electrode stack. A conductive tab extends from each of the electrode elements in the first and second sets, wherein each of the conductive tabs in the first set forms an aperture, wherein the apertures are coincident with each other. The battery further comprises a feedthrough including a feedthrough pin extending through the battery case and through each of the coincident apertures, wherein the feedthrough pin serves as a positive terminal for the battery.
