Supercapacitors coated with polyaniline layer on nanoporous gold

摘要

The present invention is a step of immersing a conductive substrate in a solution containing an aniline monomer and an electrolyte, wherein the electrolyte includes an acid; And a second step of electro-depositioning a polyaniline layer on the conductive substrate by applying an electrode to the solution, and a method of manufacturing an electrode for a supercapacitor coated with polyaniline. It relates to an electrode for a capacitor and a lithium ion battery, wherein the supercapacitor according to the present invention has a high capacitance, a maximum energy density, a fast charging/discharging speed, and excellent stability.
