Abstract

An electrode structure adapted for use in a ultracapacitor energy storage device, which expedites electrode drying time and improves impregnation of the electrode structure, is disclosed. In one embodiment, the electrode structure comprises a carbon film element having a plurality of cavities disposed thereon. In another embodiment, a plurality of channels is punched into a carbon film element of the electrode structure.

Claims (31)

1. A method of making an electrode apparatus, adapted for use in an ultracapacitor energy storage device interface, comprising the operations of:

(a.) forming a first carbon film element, having a top side and a bottom side;

(b.) providing an electrode foil element having a first side and a second side;

(c.) affixing the first carbon film element onto the electrode foil element, such that the bottom side of the first carbon film element is affixed to the first side of the electrode foil element; and

(d.) punching the first carbon film element and the electrode foil element, such that a plurality of cavities extend through the first carbon film element and the electrode foil element.

2. The method of making an ultracapacitor energy storage device electrode apparatus of claim 1 , the method farther comprising:

(e.) forming a second carbon film element having a top side and a bottom side; and

(f.) affixing the second carbon film element onto the electrode foil element, such that the top side of the second carbon film element is affixed to the second side of the electrode foil element,

wherein the plurality of cavities extend through the first carbon film element, the electrode foil element, and the second carbon film element.

3. The method of making the ultracapacitor energy storage device electrode apparatus of claim 2 , wherein the energy storage device further comprises an electrolytic solution.

4. The method of making the electrode apparatus of claim 1 , wherein the ultracapacitor energy storage device further comprises a battery element.

5. The method of making the electrode apparatus of claim 1 , wherein the plurality of cavities comprises a plurality of channels.

6. An electrode structure adapted for use in an ultracapacitor energy storage device, comprising:

(a.) a first carbon film element, having a top side and a bottom side;

(b.) an electrode foil element, having a first side and a second side, wherein the first carbon film element bottom side is affixed to the first side of the electrode foil element; and

(c.) a plurality of cavities extending through the first carbon film element and the electrode foil element.

7. The electrode structure of claim 6 , further comprising:

(d.) a second carbon film element having a top side and a bottom side, the second carbon film affixed to the second side of the electrode foil element,

wherein the plurality of cavities extend through the first carbon film element, the electrode foil element, and the second carbon film element.

8. The electrode structure of claim 7 , wherein the ultracapacitor energy storage device further comprises an electrolytic solution.

9. The electrode structure of claim 6 , wherein the ultracapacitor energy storage device further comprises an electrolytic solution.

10. The electrode structure of claim 6 , wherein the ultracapacitor energy storage device further comprises a battery element.

11. The electrode structure of claim 6 , wherein the plurality of cavities comprises a plurality of channels.

12. An article of manufacture comprising an electrode apparatus adapted for use in an ultracapacitor energy storage device, comprising:

(a.) a first carbon film element comprising, a top side, and a bottom side;

(b.) an electrode foil element having a first side and a second side, wherein the first carbon film element bottom side is operatively connected to the first side of the electrode foil element, and;

(c.) a second carbon film element comprising, a top side, and a bottom side, wherein the second carbon film element top side is operatively connected to the second side of the electrode foil element; and

(d.) a plurality of cavities extending through the first carbon film element, the electrode foil element, and the second carbon film element.

13. The article of manufacture of claim 12 , wherein the ultracapacitor energy storage device comprises an electrolytic solution.

14. The article of manufacture of claim 12 , wherein the ultracapacitor energy storage device further comprises a battery element.

15. The article of manufacture of claim 12 , wherein the plurality of cavities align axially through the first carbon element, the electrode foil element, and the second carbon element.
