Abstract Over the past decades, numerous scientists have focused on designing complicated monomers, developing new synthesis protocols, and optimizing chemical structures for realizing high‐performance organic or polymer electronics energy storage devices. However, much less attention has been paid to ionic‐ radical‐rich porous films, which are essential components of aforementioned In this study, an air‐stable, large‐area, free‐standing, viologen‐linked ionic (denoted as IPP‐V) film is developed in situ through electrochemical polymerization. This applied a device by sandwiching it between indium tin oxide (ITO) Au (i.e., ITO/IPP‐V/Au); exhibits memristive behavior with ON–OFF current ratio ≈2. After IPP‐V subjected thermal pyrolysis at 500 °C, as‐produced IPP‐V‐500) acts active material in‐plane micro‐supercapacitor high volumetric capacitance level up 4.44 F cm −3 . work not only offers convenient strategy toward large‐area films memristor, but also provides derived carbon storage.
