High-Performance, Low-Cost Ultracapacitors Built with Graphene and Carbon Nanotubes

JAP-Keidar-ultracapacitor.jpg

By combining the powers of two single-atom-thick carbon structures, researchers at the George Washington University's Micro-propulsion and Nanotechnology Laboratory have created a new ultracapacitor that is both high performance and low cost. The device, described in the Journal of Applied Physics, capitalizes on the synergy brought by mixing graphene flakes with single-walled carbon nanotubes, two carbon nanostructures with complementary properties.
