AB Activated carbon cloths have been prepared from denim cloth wastes (DCWs) through chemicalactivation with H3PO4. The effect of the H3PO4/DCWs impregnation ratio and the carbonizationtemperature on the porous texture, the chemical composition, the fibers morphology, and theelectrochemical performance has been studied. Low H3PO4/DCWs impregnation ratios lead to flexibleand microporous activated carbons cloths, whereas more fragile and rigid activated carbon cloths withhigher external surface area are produced upon increasing the amount of H3PO4. The increase in thecarbonization temperature allows for obtaining a more ordered and conductive carbon structure. Theactivated carbon prepared at 900 ºC with a H3PO4/DCWs impregnation ratio of 0.5 (w/w) exhibits thebest performance as electric double layer capacitor. This electrode shows a specific surface area of2016 m2 g-1 and the highest registered gravimetric capacitance (227 F g-1). Moreover, its flexibilityminimizes the ohmic resistance of the electrode, thus increasing the feasibility of working at highercurrent densities than the other synthesized electrodes.
