A battery can hold a lot of energy, but it takes a long time to charge it. A capacitor can be charged very quickly, but doesn't hold a comparable amount of energy.
A graphene supercharger is the best of both: it takes just seconds to charge, yet stores a lot of energy. Imagine being able to charge your spent laptop or phone battery in 30 seconds, and your electric car in a few minutes. Also, unlike batteries, Graphene supercapacitors are non-toxic.

Wikipedia defines Graphene as a "substance composed of pure carbon, with atoms arranged in a regular hexagonal pattern similar to graphite, but in a one-atom thick sheet. It is very light, with a 1-square-meter sheet weighing only 0.77 milligrams."
