THE USE OF GRAPHENE SUPERCAPACITORS IN ELECTRIC VEHICLES
The article discusses the manufacturing technology of a graphene supercapacitor, the history of its creation and the principle of operation. It is revealed that an ordinary supercapacitor is not able to provide sufficient energy density. The achievements of Korean researchers in working with prototypes of powerful graphene-based supercapacitors, whose capacity parameters are not inferior to those of lithium-ion batteries, but which can accumulate and give off their electric charge very quickly, are noted. Graphene supercapacitor is defined as a revolutionary breakthrough in the field of energy storage in a short period of time and its rapid return. As a result, the possibility of using a graphene supercapacitor in electric vehicles and a comparison of graphene with the use of traditional supercapacitors is presented.
