Flexible Asymmetric Supercapacitors via Spray Coating of a New Electrochromic Donor–Acceptor Polymer

An electroactive polymer poly[4,7-bis(3,6-dihexyloxy-thieno[3,2-b]thiophen-2-yl)]-benzo[c][1,2,5]thiadiazole is synthesized and applied as a color-changing electrode material in supercapacitors via spray coating method. Using poly(3,4-ethylenedioxythiophene) as the negative electrode, the all-polymer asymmetric supercapacitors provide an energy density of 3.5–6.3 W h kg−1 and power density of 0.6–8.8 kW kg−1.
