High gravimetric capacitance of 1079 F g−1 at a specific energy of 100.9 Wh kg−1 and a specific power of 12.1 kW kg−1 is obtained. Moreover, this approach also offers an exceptionally high area-normalized capacitance of 1.8 F cm−2. The diffusion length of protons within the PANI-NWs is estimated to be about 60 nm by electrochemical impedance analysis, which indicates that the electrochemical performance of the electrode is not limited by the thickness of PANI-NWs. The electrochemical performance of PANI-NWS/CC remains without any deterioration, even when the cell is bent under high curvature. These results clearly present a cost-effective and simple method of fabrication of the nanostructured polymers with enormous potential in flexible energy storage device applications.SupercapacitorPolyaniline nanowiresArea-normalized capacitance
