Mesoporous and hierarchical manganese dioxide (MnO 2 ) nanoplates/nanowalls were integrated into the nickel/polyethylene terephthalate conductive fabric (CF) by a simple electrochemical deposition method. By applying an external cathodic voltage to the seed‐layer‐coated CF in aqueous solution, hexagonal MnO 2 nanoplates were synthesized and then transformed into hydrous MnO 2 by oxidation in air. At an external cathodic voltage of –3 V, such MnO 2 nanoplates could be densely and uniformly covered over the overall surface of CF. Additionally, their shape was changed to a nanowall‐like construction by the reaction with hydrogen peroxide, leading to a more mesoporous and hierarchical surface morphology.
