How to make Graphene Batteries

Graphene is used in some fuel cells to help facilitate the oxidation of methanol and has been found to be much more effective than other carbon allotropes, such as carbon nanotubes and carbon black. Graphene's two-dimensional sheets provide a greater active surface area for electron/ion transport, as both sides of the sheet are exposed to the solution within the fuel cell.
