dc.description.abstract | We report the making of chemically reduced graphene (CRG) sheets separated by layer-by-layer-assembled multi-walled carbon nanotubes (MWCNTs) for electrochemical micro-capacitor applications. Submicron thin films of amine-functionalized MWCNTs (MWCNT-NH(2)) and CRG derived from graphene oxides, were shown to be cross-linked with amide bonds having high packing densities of similar to 70%. These carbon-only electrodes were found to have large volumetric capacitance of similar to 160 F/cm(electrode)(3) in an acidic electrolyte (0.5 M H(2)SO(4)). The electrode capacitance in a neutral electrolyte (1 M KCl) was found much lower, which supported the hypothesis that the observed high capacitances in the acidic electrolyte can be attributed primarily to redox reactions between protons and surface oxygen-containing groups on carbon. | - |
