Flexible redox supercapacitors based on treated carbon cloths were prepared by introducing methylene blue into a gel electrolyte. With the improvement in pseudocapacitance and broadening of the voltage window, the device exhibited a high capacitance of 1738 mF cm⁻² and an energy density of 0.78 mW h cm⁻². In addition, 84.6% capacitance retention was achieved over 8000 cycles.
