Redox-active organic electrode materials are highly desirable in realizing next-generation all-in-one bendable electronic systems.Herein,a novel flexible supercapacitors (SCs) electrode is fabricated from poly(anthraquinonyl sulfide) (PAQS) and single-walled carbon nanotubes (SWCNTs) suspension by a simple vacuum filtration and named as PAQS-SWCNTs.The PAQS-SWCNTs electrode offered an initial capacitance of 223 F·g-1 and outstanding capacitance retention up to 78.4% after 3 x 104 charge-discharge cycles at 0.5 A·g-1 current density.In a high potential range (0-3 V) and aprotic electrolyte,the PAQS-SWCNTs electrodes in coin cell exhibited an outstanding energy density of 69 Wh·kg-1 at a power density of 90.6 W·kg-1,whereas in the fabricated flexible SCs it retained 63.2 Wh·kg-1.The PAQS-SWCNTs electrodes also showed extraordinary performance at a higher current density (20 A·g-1) and maintained a specific capacitance of 55 and 47 F·g-1 for coin and flexible SCs,respectively.Moreover,the flexible SC is further verified to be able to illuminate up multiple LEDs.These futuristic findings showed that the SCs assembled with flexible PAQS-SWCNTs electrodes have potential application in energy-storage devices and make them highly appealing for future redox supercapacitors.
