The present subject matter includes a capacitor stack having a first element having at least one first anode and at least one first cathode and a second element having at least one second anode and at least one second cathode. The capacitor stack is formed by the process of aligning the first element and the second element so that a first anode edge face of the first anode and a second anode edge face of the second anode form an anode connection surface for electrical connection of the first anode and the second anode. Additionally, the capacitor stack is formed by spraying metal on the anode connection surface to electrically connect the first anode and the second anode.
