Adding graphene could mean cheaper Lithium-ion batteries

It’s not only integrated circuits that look set to benefit from the use of graphene, the one-atom thick wonder material made up of a honeycomb lattice of carbon atoms. Researchers have discovered that adding graphene to titanium dioxide for use as electrodes in batteries improves performance over standard titanium oxide by a factor of three. This could pave the way for inexpensive titanium dioxide to replace the expensive, rare-earth metals or fire-prone carbon-based materials used in today's lithium-ion batteries.
