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.
