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. |

DETAILED DESCRIPTION What is claimed is: 1.
A method of manufacturing a flat capacitor stack, comprising: forming a plurality of capacitor layers, each capacitor layer including a separator layer attached to a capacitor foil layer; and placing each of the plurality of capacitor layers onto a capacitor stack by aligning each of the capacitor layers using an outer edge of the separator layer of the capacitor layer as an alignment means.
2.
The method of claim 1, wherein aligning includes positioning the separator layer such that two or more points on an outer edge of the separator layer contact two or more corresponding alignment members.
3.
The method of claim 1, further comprising pressing the capacitor stack to a specified, predetermined height after the capacitor stack has been formed.
4.
The method of claim 1, further comprising annealing the capacitor stack after the capacitor stack has been formed.
5.
The method of claim 1, wherein placing each of the plurality of capacitor layers includes: providing an alignment mechanism; and placing each capacitor layer within the alignment mechanism such that an outer edge of each separator layer contacts one or more alignment members of the alignment mechanism.
6.
The method of claim 1, wherein forming a plurality of capacitor layers includes forming a first anode stack having or more anode layers and having a first surface area, and forming a second anode stack having or more anode layers and having a second surface area, wherein the first surface area is greater than the second surface area.
7.
The method of claim 6, wherein the second anode stack has one or more less anode layers than the first anode stack.
8.
A flat capacitor having a capacitor stack formed by a method including: forming a plurality of capacitor layers, each capacitor layer including a separator layer attached to a capacitor foil layer; and placing each of the plurality of capacitor layers onto a capacitor stack by aligning each of the capacitor layers using an outer edge of the separator layer of the capacitor layer as an alignment means
