Abstract
An electrode useful in an energy storage system, such as a capacitor, includes an electrode that includes at least one to a plurality of layers of compressed carbon nanotube aggregate. Methods of fabrication are provided. The resulting electrode exhibits superior electrical performance in terms of gravimetric and volumetric power density.
Claims19
An electrode comprising:
- a current collector comprising a first layer of compressed carbon nanotubes disposed thereon and a second layer of compressed carbon nanotubes disposed directly on the first layer of compressed carbon nanotubes.
A method for fabricating an electrode, the method comprising:
- selecting a current collector comprising a bonding layer disposed thereon;
- bonding to the bonding layer another bonding layer comprising a layer of aligned carbon nanotubes disposed thereon;
- and
- removing a substrate from the carbon nanotubes thus exposing the carbon nanotubes.
