In this study, vanadium-doped polyaniline and vanadium-doped polypyrrole were made by chemical synthesis method, with the addition of vanadium species used as oxidant for the first time in the literature. The prepared vanadium-doped conductive polymers were characterized spectroscopically, microscopically, and physically. In this context, vanadium-containing species both covalently doped to the structure of conductive polymers and adsorbed were determined by XPS and FT-IR analyzes. After characterizing the vanadium-doped conductive polymers prepared using chemical synthesis method, they were used as electrode material in asymmetric type supercapacitors. The highest areal capacitance was determined in VDPA including supercapacitor as 453−2 at a scanning speed of 5 mV.s−1. In long-cycle tests, it was determined that this system retained 70.9% of its initial capacity at the end of 1000 cycles. The data obtained in this study, which is the first to demonstrate the supercapacitor application of vanadium-doped conductive polymers, show that these material compositions have a high capacitance value and form an important basis for future studies.
