Electrochemists are racing to develop new organic and inorganic materials for batteries and supercapacitors. As Organic Radical Battery technology approaches, a wide variety of materials are being proposed. However, devising materials with both ionic conductivity and redox storage properties is a strategy to be explored. In this paper, we show a new composite based on mixing carbon nanotubes and redox ionic liquids. The present work's originality is that this composite is realized for the first time and allows a couple of different types of conduction/storage: electronic conduction via carbon nanotubes, ionic conduction via ionic liquids, and redox transport via redox molecules. Flexible composite materials comprised carbon nanotubes and poly(imidazolium) with allyl and redox pendant groups were fabricated and examined. They demonstrated ionic and electrical conductivity and the faradaic response of the redox-polymerized ionic liquid.
