Patent ID: 7846217

Claim:
A method, comprising: joining a first connection member to an unetched connection area, the unetched connection area located on a single major surface of a first planar anode; forming a capacitor stack by aligning the first planar anode with at least a second planar anode, the second planar anode including at least a second connection member, the first connection member and the second connection member for electrical connection of the first planar anode to the second planar anode; filling a space defined by the first planar anode, the first connection member, and a further anode layer stacked onto the first planar anode and the first connection member by stacking into the space a first separator, a cathode and a second separator into the space; aligning the first connection member and the second connection member to define an anode connection surface; and joining the first planar anode and the second planar anode.
