Patent ID: 7872857

Claim:
An apparatus, comprising: at least a first element having a first element thickness, including at least a first substantially planar electrode with a first connection member, at least a second substantially planar electrode, and a first spacer member disposed below the first connection member; and at least a second element having a third substantially planar electrode with a second connection member disposed below the first spacer member, the first element and the second element stacked in alignment and defining a capacitor stack, the capacitor stack disposed in a case containing electrolyte, with a second spacer member disposed below the second connection member, the first spacer member and the second spacer member part of a unitary spacer including a main spacer body, the unitary spacer to position several spacer members, wherein the first spacer member, the first connection member, and the second connection member are in adjacent alignment defining a connection surface for electrical connection of the first substantially planar electrode and the third substantially planar electrode, with the adjacent first spacer member and first connection member having a first thickness approximately equal to the first element thickness, wherein the first spacer is plastic.
