Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>In order to achieve pesudocapacitive performance of single‐wall carbon nanotube (SWCNT) electrodes, a high‐efficient and reversible redox strategy utilizing a redox‐mediated electrolyte for SWCNT‐based supercapacitors is reported. In this novel redox‐mediated electrolyte, the single‐electrode specific capacitance of the supercapacitor is heightened four times, reaching <italic>C</italic>=162.66 F g⁻¹ at 1 A g⁻¹. The quick charge‐discharge ability of the supercapacitor is also enhanced, and the relaxation time is as low as 0.58 s. Furthermore, the supercapacitor shows an excellent cycling performance of 96.51 % retention after 4000 cycles. The remarkable results presented here illustrate that the redox strategy is a facile and straightforward approach to improve the performances of SWCNT electrodes.</p> </abstract>
