Belgrade’s buses use supercapacitors made from layers of activated carbon, which is coated onto conductive plates immersed in an electrolyte solution. Graphene is also a form of carbon, but because of its huge surface area (which determines the performance of a supercapacitor) it has the potential to radically improve the performance of supercapacitors to a level where they become practical for electric cars and consumer devices. It could create smartphones that charge in seconds, and cars that can refuel while they’re stopped at a set of traffic lights.
There’s still work to do before graphene supercapacitors can hold their charge for long enough to be a practical alternative to lithium-ion for most applications, however. Some have suggested hybrid systems – supercapacitors for fast-charging, with traditional batteries for long-term storage.
Another potential problem could be scaling up production – because of the hype, the graphene industry has become a minefield of broken promises and shoddy quality control. Last month, the UK’s National Physical Laboratory launched an initiative to help companies verify whether they’re actually getting what they pay for when they buy graphene.
