Graphene on vanadium oxide ‘ribbons’ shows promise for lithium-ion battery cathodes

By Eileen De Guire / March 26, 2013

Graphene-coated ribbons of vanadium oxide, seen in a scanning electron microscope image, show promise as electrode for lithium-ion batteries, according to researchers at Rice University. (Credit: Ajayan Group/Rice University) Last week I told you about some fascinating work coming out of the University of Stuttgart on extremely flexible vanadium pentoxide paper like material. Researchers are…
