Researchersat MIT are developing a lithium-ion battery with a positive electrodemade of carbon nanotubes that delivers 10 times more power than aconventional battery and can store five times more energy than aconventional ultracapacitor.
The high surface area and high conductivity of carbon nanotubes promise improvements in both energy and power density.
The MIT researchers led by chemical engineering professor Paula Hammond and mechanical engineering professor Yang Shao-Horn, showed in their article published in the Journal Nature Nanotechnologythat the development of methods for careful structural control at thenanoscale leads to major improvements in materials performance.According to Nicholas Kotov, professor of chemical engineering at the University of Michigan, we are just at the beginning of the major improvement of lithium batteriesusing a materials engineering approach.
