Herein, we with organic electrolyte (1 M tetraethylammonium present fabrication and characterization of nanostructured tetrafluoroborate in acetonitrile) yielding a total capaci- supercapacitor electrodes using manganese dioxide and tance of nearly 2.8 F at 2.5 V and a corresponding specific -1 carbon nanotubes (MnO /CNTs) on flexible graphite foil capacitance of 388 F g was calculated for MnO . High 2 2 substrate for integration into a supercapacitor prototype cell capacitance and a low DC resistance yield a maximum -1 cell, without any additives or binders.
