1. A supercapacitor, comprising:
a negative electrode comprising a carbon material and a substrate, wherein the carbon material is at least one selected from the group consisting of a poly-anthraquinone sulfide activated carbon material and a poly-anthraquinone sulfide reduced activated carbon material, and wherein the carbon material is coated on the substrate and the substrate is a metal foil;
a positive electrode comprising a carbon material and a substrate, wherein the carbon material is at least one selected from the group consisting of a poly-anthraquinone sulfide activated carbon material and a poly-anthraquinone sulfide reduced activated carbon material, and wherein the carbon material is coated on the substrate and the substrate is a metal foil;
an electrolyte;
a separator,
wherein the separator is between the negative electrode and the positive electrode, and the electrolyte is present in and on the separator.
