1. A nanocomposite supercapacitor, comprising:
first and second nanocomposite electrodes, a membrane separator and an electrolyte,
wherein the first nanocomposite electrode comprises a first substrate and the second nanocomposite electrode comprises a second substrate,
wherein the electrolyte and the membrane separator are between and in direct contact with the first and second electrodes,
wherein both the first and the second substrates are made from at least one material selected from the group consisting of stainless steel, aluminum, nickel, copper and platinum;
wherein both the first and the second substrates are coated on a surface contacting the membrane separator with a nanocomposite mixture comprising:
polyvinylidene fluoride as a binding compound;
at least one carbonaceous compound; and
vanadium doped spinel ferrite nanoparticles (V-SFNPs);
wherein the V-SFNPs have a formula of CoxNi1-xVyFe2-yOz;
wherein x=0.1-0.9, y=0.01-0.10, and z=3-5.
