Ultracapacitors and supercapacitors are elements that can store electrical charge, and it is expected that they will be useful in many applications, including electric cars. Supercapacitors, unlike batteries, can store or deliver electric charge very quickly.
An article about graphene ultracapacitors is available as a PDF file from Rodney Ruoff's research group website at the University of Texas at Austin.
Graphene has the same hexagonal structure as graphite sheets. Because of its high conductivity and specific surface area, the material is very promising for electrical applications.
