Using carbon nanotubes in lithium batteries can dramatically improve energy capacity

Batteries might gain a boost in power capacity as a result of a new finding. Researchers found that using carbon nanotubes for one of the battery's electrodes produced a significant increase -- up to tenfold -- in the amount of power it could deliver from a given weight of material, compared to a conventional lithium-ion battery. Such electrodes might find applications in small portable devices, and with further research might also lead to improved batteries for larger, more power-hungry applications.
