Abstract
The present disclosure relates to energy storage or collection devices and methods for making such devices having electrode materials containing exfoliated nanotubes with attached electro- or photoactive nanoscale particles or layers. The exfoliated nanotubes and attached nanoscale particles or layers may be easily fabricated by methods such as coating, solution or casting or melt extrusion to form electrodes. Electrolytes may also be used for dispersing nanotubes and also in a polymeric form to allow melt fabrication methods.
Claims27
An energy storage and collection device comprising:
- a) at least two electrodes;
- b) at least one of the electrodes containing carbon or mineral nanotubes that have been exfoliated from their as-synthesized state and have attached electroactive or photo active nanoscale particles or layers;
- c) at least two current collectors, each in contact with an electrode, or the electrode also functions as the current collector;
- and
- d) optionally an insulator.
An energy storage device comprising:
- a) at least two electrodes;
- b) at least one of the electrodes containing carbon or mineral nanotubes that have been exfoliated from their as-synthesized state and have attached electroactive or photoactive nanoscale particles or layers;
- c) at least two current collectors, each in contact with an electrode, or the electrode also functions as the current collector;
- d) an electrolyte disposed between said electrodes;
- and
- e) optionally a separator disposed in said electrolyte to provide electrical insulation between the electrodes while allowing ion flow within said electrolyte.
An energy storage or collection device comprising:
- a) at least two electrodes;
- b) at least one of the electrodes containing carbon or mineral nanotubes that have been exfoliated from their as-synthesized state and have attached electroactive or photoactive nanoscale particles or layers;
- and
- c) an electrolyte comprising a lithium salt and optionally an organic solvent.
A method for making an energy storage or collection device comprising:
- dispersing exfoliated nanotubes with attached nanoscale particles or layers in a medium to create an electrode;
- and
- joining the electrode with another media acting as a dielectric or electrolyte.
An energy storage or collection device that comprises exfoliated nanotubes with attached nanoscale particles and layers that provides increased strength and ruggedness to the device compared to devices without exfoliated nanotubes.
