Abstract

Embodiments of the present invention are directed to an energy storage device and a method for manufacturing the energy storage device. The method includes accessing a metal substrate and forming plurality of carbon nanotubes (CNTs) directly on a metal substrate. The method further includes removing substantially all amorphous carbon from said plurality of CNTs and coupling the plurality of CNTs to an electrolytic separator.

Claims (22)

1 . A method for forming a portion of an energy storage device, said method comprising:

accessing a metal substrate;

forming plurality of carbon nanotubes (CNTs) directly on a metal substrate;

removing amorphous carbon from said plurality of CNTs; and

coupling said plurality of CNTs to an electrolytic separator.

2 . The method of claim 1 wherein said metal substrate comprises a metal catalyst.

3 . The method of claim 1 wherein said metal substrate is coated with a metal catalyst.

4 . The method of claim 1 wherein said plurality of CNTs are grown directly on said metal substrate without addition of a catalyst layer.

5 . The method of claim 1 wherein said amorphous carbon is removed via a process involving water.

6 . The method of claim 1 wherein said plurality of CNTs is substantially vertically aligned.

7 . The method of claim 1 wherein said plurality of CNTs are formed via chemical vapor deposition (CVD).

8 . A method of forming a capacitor, said method comprising:

forming a first plurality of carbon nanotubes (CNTs) on a first metal substrate;

removing amorphous carbon from said first plurality of carbon nanotubes (CNTs);

forming a second plurality of carbon nanotubes (CNTs) on a second metal substrate;

removing amorphous carbon from said second plurality of CNTs; and

coupling said first plurality of CNTs and said second plurality of CNTs to a membrane.

9 . The method of claim 8 , wherein said first metal substrate and said second metal substrate comprise a metal catalyst.

10 . The method of claim 8 , wherein said first metal substrate and said second metal substrate are coated with a metal catalyst.

11 . The method of claim 8 , wherein said first plurality of CNTs are grown on said first metal substrate without addition of a catalyst layer.

12 . The method of claim 8 , wherein said first plurality of CNTs is substantially vertically aligned.

13 . The method of claim 8 wherein said membrane is an electrolytic separator.
