1. A supercapacitor, comprising:
a first electrode and a second electrode; and
a gel polymer electrolyte arranged between the first and the second electrodes;
wherein the first and the second electrodes each comprises:
a metallic current collector; and
a conductive layer comprising a conductive carbon and a polymer binder disposed on the current collector,
wherein the polymer gel electrolyte is in electrical contact with the conductive layers of the first and the second electrodes, and
wherein the gel polymer electrolyte comprises:
a hydrogel matrix comprising water and a copolymer comprising 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) and at least one comonomer selected from the group consisting of 2-hydroxyethyl methacrylate, 3-sulphopropyl acrylate, 2-sulphoethyl methacrylate and N-vinylpyrrolidone; and
a molybdate(VI) salt dispersed in the hydrogel matrix,
wherein the molybdate(VI) salt is present in an amount of from 3.0 wt % to 20.0 wt % relative to a total weight of the hydrogel matrix.
