Rice lab finds vanadium oxide/graphene material works well
for lithium-ion storage
Hybrid ribbons of vanadium oxide (VO2) and graphene may
accelerate the development of high-power lithium-ion batteries suitable for
electric cars and other demanding applications.
The Rice University lab of materials scientist Pulickel
Ajayan determined that the well-studied material is a superior cathode for
batteries that could supply both high energy density and significant power
density. The research appears online this month in the American Chemical
Society journal Nano Letters.
