Abstract:
1. An electric double layer capacitor (EDLC) device comprising: a housing; a first storage cell and a second storage cell each positioned in the housing, wherein the first and second storage cells are electrically connected in series with one another, wherein each of the first and second storage cells comprise a generally planar anode, a generally planar cathode extending parallel to but spaced from the planar anode, and a separator therebetween; and a sealing conductor establishing the series connection between the first and second storage cells, the sealing conductor comprising a body having a flat and planar outer extremity extending parallel to but spaced from the generally planar anode and the generally planar cathode of each of the first and second storage cells, the sealing conductor being mechanically retained in position between the first and second storage cells via the flat and planar outer extremity; and the flat and planar outer extremity being electrically insulated from the housing; wherein the body of the sealing conductor further comprises a flat end wall and a cylindrical side wall extending generally perpendicular to the flat end wall; wherein the flat end wall extends between the first storage cell and the second storage cell; and wherein the cylindrical side wall includes a first end and a second end opposing the first and, the flat end wall extending from the first end, and wherein the flat and planar outer extremity of the sealing conductor extends from the second end of the cylindrical side wall.
