Carbon Nanotubes in Batter applications:
1. Carbon material with huge reserves, low
prices, good electrical conductivity of carbon nanotubes, light absorption
rate, especially for the production of solar cells. Most solar cell material is
silicon, the photoelectric conversion rate from 10 to 30%. This ratio is also
good, but the silicon price is very expensive.
2. Carbon nanotubes in polymer solar cells was
first used as a transparent electrode to replace conventional indium tin oxide
conductive film. Carbon nanotube film has good light resistance, chemical
stability and flexibility.
3. Carbon nanotubes in dye-sensitized solar
cells can be improved to increase its transparent conductive film thickness.
Nanotubes also due to its high specific surface area, but also promote the role
of sensitizer adsorption, add multi-walled carbon nanotubes in Tio2 films, can
make the rough factor of TiO2 film improved 1.5 times, thereby adsorb more
sensitizer.
4. Carbon nanotubes in solar cells have a
transparent conductive electrode, an auxiliary charge separation, collection
and transport of charge effects.
5. Carbon nanotubes are crimped by a single or
multi-dimensional graphite from tubular nanomaterials has many outstanding
physical and chemical properties, its unique electronic conductivity, it has alithium-ion battery lure in terms of conductive agent human application.
6. As a new fibrous carbon nanotube conductive
agent, a complete three-dimensional structure of the conductive network,
compared with the conventional conductive agent such as conductive carbon
black, carbon nanotubes have higher electron conductivity, the required amount
relatively low, help improve battery capacity, improve battery cycle life,
especially beneficial to improve the battery charge and discharge performance
magnification.
7. Has a unique structure, suitable surface
area, low resistance, high stability and an inner diameter of adsorbed
molecules suitable for their size and other characteristics, in a fuel cell
catalyst support has a good prospect.
8. Has the unique structure of carbon nanotubes,
a suitable surface area, low resistance and high stability, which is widely
used in fuel cell catalyst, activated carbon or carbon black is superior to the
catalyst carrier.
