Studies from Lanzhou University Yield New Data on Nanostructures (Porous CoO nanostructures grown on three-dimension graphene foams for supercapacitors electrodes)

By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Nanostructures are presented in a new report. According to news reporting from Lanzhou, People's Republic of China, by NewsRx journalists, research stated, "Three-dimensional graphene foams with good conductivity, light weight and chemical stability were produced by chemical vapor deposition. Then porous Co0 nanowalls were deposited on graphene foam by a simple hydrothermal process and subsequent thermal treatment."

The news correspondents obtained a quote from the research from Lanzhou University, "This hybrid structures possessing large surface area in which the Co0 nanowalls are separated by graphene foam with robust adhesion can directly serve as supercapacitor electrode including current collector without the need of any other binder materials and conductive agents. Electrochemical tests manifest a high specific capacitance of 231.87 F/g scaled to the mass of Co0 (139.47 Fig for total mass of electrodes) at 1 A/g current, good rate capability and excellent cycling performance of >98% capacitance retention over 1000 cycles at 7 A/g current."

According to the news reporters, the research concluded: "The high conductivity, light weight and rational architectures, which provide fast electron pathway and the low diffusion resistance of ions, are responsible for the high performance of the electrodes."
