논문 초록 (Abstract)
Composite electrodes consisting of Mn-Co oxide and high electrical conductive carbon nanofibers(vapor grown carbon nanofiber, VGCF)(CoMnO2/VGCF) were prepared by thermally decomposing manganese and cobalt nitrates directly onto the pore ofa porous nickel foam substrate as a current collector to form manganese and co balt oxides, and their supercapacitiveproperties were investigated us ing cyclic voltammetry in 1M KOH aqueous solution. The CoMnO2/VGCF e lectrodes exhibitedhigh specific capacitance value of 630 F/g at 5 mV/s and excellent capacitance retention of 95% after 10(4) cycles .
