Scientists hike battery energy capacity
CAMBRIDGE, Mass., Jun 21, 2010 -- UPI
U.S. scientists say they've discovered the use of carbon nanotubes for
one of a lithium battery's electrodes can dramatically improve its
energy capacity.
The Massachusetts Institute of Technology researchers said they
determined the use of carbon nanotubes can produce a significant
increase -- up to tenfold -- in the amount of power the battery could
deliver from a given weight of material, compared with a conventional
lithium-ion battery.
They said 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.
The findings by a team led by Associate Professor Yang Shao-Horn and
Professor Paula Hammond, which included researchers Naoaki Yabuuchi and
Seung Woo Lee, are reported in the journal Nature Nanotechnology.
