Abstract
A method of making a supercapacitor including mixing aniline and an acid to form a solution, contacting a reference electrode, a counter electrode, and a steel substrate with the solution to form an electrodeposition system, applying a potential of from greater than 0 to about 2 volts (V) to the electrodeposition system, and depositing particles of polyaniline on a surface of the steel substrate to form a polyaniline electrode. The particles of the polyaniline have an oval sheet morphology with an average length of 100-300 nanometers (nm) and an average width of 50-150 nm. The method includes assembling two of the polyaniline electrodes in a symmetrical layered configuration with the surfaces having the particles of the polyaniline facing each other. An electrolyte is present between the two polyaniline electrodes to form the supercapacitor.
