The most critical aspect to keep in mind is the efficiency of the supercapacitor. Recently, scientists from First Graphene Limited have produced graphene supercapacitors that can store 140 F/g. This is a watershed moment in supercapacitor materials when compared against the current technology of activated carbon, which typically has a specific capacitance of only 35 F/g.
The Future of Graphene Supercapacitors
Within the next five years, graphene supercapacitors are likely to be utilized in laptops, smartphones, electronics, public transportation, and many other applications due to increased development in terms of energy storage limits.CRRC, for example, has announced the launch of an electric train that uses a graphene supercapacitor to store energy when braking and then convert that energy to power the train when accelerating.We will see a flexible, lightweight smartphone powered by graphene supercapacitor in the next few years that charges at a much faster rate than current batteries and lasts for a very long time.
