Definitions
- the present invention relates to producing electrodes comprising carbon nanotube aggregates for use in energy storage devices, including methods for producing such electrodes and energy storage devices that utilize such electrodes.
- Carbon nanotubes are carbon structures that exhibit a variety of properties. Many of the properties suggest opportunities for improvements in a variety of technology areas. These technology areas include electronic device materials, optical materials as well as conducting and other materials. For example, CNTs are proving to be useful for energy storage in capacitors.
- a bonding layer is typically used to cause CNTs to adhere to the surface of a current collector.
- the bonding layer typically affects the performance of the resulting capacitor in a number of ways, including increasing the ESR and decreasing the energy density and power density.
- the methods and apparatus are simple to perform and thus offer reduced cost of manufacture, as well as an improved rate of production.
- an electrode in one embodiment, includes a current collector comprising aluminum with an aluminum carbide layer on at least one surface, on which at least one layer of CNTs is disposed.
- the electrode may comprise vertically-aligned, horizontally-aligned, or nonaligned (e.g., tangled or clustered) CNTs.
- the electrode may comprise compressed CNTs.
- the electrode may comprise single-walled, double-walled, or multiwalled CNTs.
- the electrode may comprise multiple layers of CNTs.
- a method for fabricating an electrode comprises selecting a current collector with a layer of aluminum carbide on at least one surface of the current collector and disposing CNTs onto the aluminum carbide layer.
- Disposing CNTs onto the aluminum carbide layer may comprise disposing vertically-aligned, horizontally-aligned, or nonaligned (e.g., tangled or clustered) CNTs.
- the resulting electrode may comprise vertically-aligned, horizontally-aligned, or nonaligned (e.g., tangled or clustered) CNTs.
- Disposing CNTs onto the aluminum carbide layer may comprise disposing compressed CNTs and/or compressing the CNTs after they have been disposed on the aluminum carbide layer.
- the resulting electrode may comprise compressed CNTs.
- Disposing CNTs onto the aluminum carbide layer may comprise disposing single-walled, double-walled, or multiwalled CNTs.
- the resulting electrode may comprise single-walled, double-walled, or multiwalled CNTs.
- the method may further comprise disposing additional layers of CNTs onto the layer of CNT disposed onto the aluminum carbide layer, which additional layers of CNTs may be vertically-aligned, horizontally-aligned, or nonaligned (e.g., tangled or clustered) CNTs; compressed CNTs; or single-walled, double-walled, or multiwalled CNTs.
- Disposing CNTs onto the aluminum carbide layer may comprise any variety of methods for creating a layer of CNTs on a surface, including transferring CNTs from a solution, transferring CNTs using any variety of dry transfer methods, growing CNTs directly on the aluminum carbide layer, and any combination of these methods.
- a layer of CNTs is grown directly on an aluminum current collector having an aluminum carbide layer on at least one surface.
- the layer may comprise single-walled, double-walled, or multiwalled CNTs.
- a layer of CNTs is transferred to the current collector using any variety of dry transfer methods, such as transfer tape, compression.
- a dry transfer method is used to add additional layers of CNTs onto a layer of CNTs that has been disposed onto an aluminum carbide layer of the current collector.
- a layer of CNTs is transferred to the current collector using any variety of wet, solvent-based transfer methods, including precipitation, evaporation, spray-drying,
- an ultracapacitor is provided.
- the ultracapacitor includes at least one electrode of the type described herein.
- the ultracapacitor may further comprise an electrolyte with certain desired properties in terms of the electrical performance and compatibility with the other materials of the ultracapacitor, e.g., the electrode or separator.
