Hybrid Carbon Nanotube Metal Oxide Arrays to Improve Lithium Battery Technology
By | April 12, 2009
This reent article from Rice University just backs up our claim that carbon nanotube technology is the future for battery technology:
Researchers at Rice University in Houston, Texas, have created hybrid carbon nanotube metal oxide arrays as electrode material that may improve the performance of lithium-ion batteries. The research group combined highly electrically conducting carbon nanotubes and manganese oxide in a novel formation in which the nanotubes are grown to look, and act, like the coaxial conducting lines used in cables. The tubes have a manganese oxide shell, which is high capacity but low conductivity, and a nanotube core, which is high conductivity and absorbs lithium, with the resulting combination producing enhanced capacity and efficiency. According to Pulickel Ajayan, professor of mechanical engineering and materials science at Rice University, “Although the combination of these materials has been studied as a composite electrode by several research groups, it’s the coaxial cable design of these materials that offers improved performance as electrodes for lithium batteries.” Improved battery technology is a necessary part of the increasing demand for electric cars and other gadgets that last longer between charges. The Rice researchers say that electrochemical capacitors and fuel cells would also benefit from their findings.
