Abstract: Provided is an anodeless electrode, and more particularly, to an anodeless electrode including a current collector, and a conductive flexible thin-film layer disposed on the current collector. The conductive flexible thin-film layer includes a conductive polymer, a soft polymer, and metal nanoparticles. The metal nanoparticles have a diameter of about 20 nm to about 100 nm, and are contained in an amount of about 20 wt % to about 50 wt % with respect to the sum of weights of the conductive polymer and the soft polymer.
