UNC Says Nanotubes Boost Battery Energy Storage.(University of North Carolina)
Electric Vehicle Online Today, January, 2002
Researchers at the University of North Carolina (UNC) are working with carbon nanotubes in an effort to increase the energy storage potential of batteries. In their experiments, the carbon nanotubes are being used as a substitute for standard graphite electrodes.
Using laser technology to create single-wall carbon nanotubes, the researchers implanted them in lithium ion batteries. The closed ends of the nanotubes were opened, which allowed lithium ions to diffuse more efficiently inside the nanotubes.
The experiments have led the researchers to the finding that carbon nanotubes contain twice the energy density of conventional graphite.
"Scientists and others, including the popular press, have shown a lot of interest in carbon nanotubes...
