Improving the capacity of lithium batteries using carbon nanotubes
Researchers at MIT found that using carbon nanotubes to an electrode of a battery produces a significant increase – up to ten times – in the amount of energy that could offer from a given weight of material, compared with a battery Conventional lithium ion. These electrodes may find applications in small portable devices, and further research could also lead to improved batteries for large applications.
To produce the new electrode material, the team used a method of making layer by layer, in which a base material is dipped alternately into solutions containing carbon nanotubes have been treated with simple organic compounds that give a net charge either positive or negative.
When these alternating layers on a surface, strongly adhere to each other due to additional costs, making a stable and durable film.
Lithium batteries with the new material show some advantages of the two capacitors, which can produce very high power output in short bursts, and lithium batteries that can provide lower power consumption steadily over long periods.
