Researchers at the University of California, Riverside developed a metal oxide modified nanocarbon graphene foam that can be used to increase the performance of supercapacitors (both density and charge times). The researchers say this new foam can enable supercapacitors that can deliver twice the energy compared to current commercial devices.

The researchers report that the graphene foam is used as an electrode system. The researchers developed a process that is scalable. They also report that the foam electrode was successfully cycled over 8,000 times with no fading in performance.
