Abstract All-conducting polymer batteries, in which both the anode and cathode consist of films made of perchlorate-doped pure poly(3,4-ethylenedioxythiophene) (PEDOT), alternated layers of PEDOT and poly(N-methylpyrrole) or PEDOT/clay nanocomposites, have been fabricated. Batteries, which have been used as power source for a LED bulb, are rechargeable and exhibit excellent charge/discharge cyclability and stability. The organic devices prepared using PEDOT and multilayered films have been found to be promising platforms to achieve metal-free power sources. Thus, these materials, in particular the multilayered films, show a dual behavior being useful for the fabrication of both capacitors and batteries.
