1. A nanocomposite electrode supercapacitor, comprising:
a first electrode, a second electrode and a separator, wherein the separator is between the first electrode and the second electrode and the first electrode, the second electrode and the separator form a symmetrical layered structure,
wherein the first electrode and the second electrode each comprise:
a substrate made from aluminum;
polyvinylidene fluoride as a binding compound;
at least two carbonaceous compounds selected from the group consisting of graphite, activated carbon, reduced graphene oxide, and carbon black; 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;
wherein the substrate is at least partially coated on a first side with a mixture comprising the V-SFNPs, the binding compound, and the carbonaceous compounds.
