Graphite oxides boost supercapacitors

"Researchers in the US have discovered a new form of carbon produced by "activating" expanded graphite oxide. The material is full of tiny nanometre-sized pores and contains highly curved atom-thick walls throughout its 3D structure. The team has also found that the material performs exceptionally well as an electrode material for supercapacitors, allowing such energy-storage devices to be used in a wider range of applications."
