Abstract

In one aspect, a method of manufacturing a capacitor includes disposing one or more conductive layers of a first electrode stack in a recess of an alignment mechanism, where the recess is positioned relative to two or more alignment elements. The method further includes placing a separator over the one or more conductive layers where an outer edge of the separator contacts the two or more alignment elements. In one embodiment, a capacitor includes anode and cathode foils having offsetting edge portions. In one embodiment, a multiple tab cathode for a flat capacitor. A plurality of cathode tabs are portioned into a plurality of cathode tab groups positioned in different locations along the edge of the capacitor stack to reduce the amount of space required for connecting and routing the cathode tabs.
