HIGH PERFORMANCE CARBON NANOTUBE ENERGY STORAGE DEVICE
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.
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.
