A series of metal oxide nanocomposites have been successfully synthesized by electrospinning technology. The obtained nanocomposites (Cu 2 O-Mn 3 O 4 -NiO) are an ordered arrangement of metal oxide particles (10 $$ nm), with the shape like bead chain. The acquired Cu 2 O-Mn 3 O 4 -NiO ternary nanocomposites were used as electrode materials to manufacture a supercapacitor. Electrochemical tests showed that the synthesis of nanocomposites made of electrode materials had good electrochemical performance in 6 $$ mol/L KOH electrolyte. The results showed that at a scan rate of 5 $$ mV/s, the specific capacitance of Cu 2 O-Mn 3 O 4 -NiO had a larger specific capacitance of 1306 $$ F/g than NiO, Cu 2 O-NiO and Mn 3 O 4 -NiO. The excellent electrochemical performance showed that the electrostatic spinning method is an effective technology for developing nanocomposites for energy storage devices.
