Angstron Materials Inc. has invented a graphene-based supercapacitor with ultra high energy density. Along with the capacitors, Angstron offers a variety of graphene materials for use in electromagnetic interference, electrostatic discharge, lightning strike and other functional and structural composite applications. Angstron’s graphene-based supercapacitor has demonstrated an energy density that exceeds that of commercially available supercapacitors and is comparable with nickel metal hydride batteries.
