The element Graphene probably means nothing to you. However, it is part of the composition of one of the most common objects that is near you: a pencil. Graphene is a two-dimensional sheet of carbon atoms organized in a honeycomb structure and its stack forms the graphite of our pencil mines. Graphene was discovered in 2004 by two physicists, Andre Geim and Konstantin Novoselov when it was believed to be physically impossible. Graphene has incredible properties, to the point that it c …

Supercapacitors are formed by pairs of conductive plates separated by a dielectric medium. Its operation is very similar to that of a large-scale capacitor. However, the name of the supercapacitor indicates its greater capacity, thousands of times greater than the capacity of high capacity electrolytic capacitors, being able to charge and discharge in very short periods. Graphene has a lot of potential in the construction of Supercapacitors, therefore this article aims to discuss the role …
