Dr Lu has managed to produce sufficient quantities of graphene in a form that can be used in a supercapacitor, The Economist reports. First he produced graphite oxide. Next, he heated it to split the graphite into graphene sheets. Then he removed the surplus oxygen. Finally he incorporated the graphene sheets into a supercapacitor.

The supercapacitor worked well. It stored as much energy per kilogram as a lithium-ion battery and could be charged up in less than four minutes. It is likely that a refined version of the supercapacitor will exceed lithium-ion batteries’ storageDrivers could save £400 each year - Read more about this great deal.

The next stage will be to scale up the technology and commercialise it.
