By employing a permanganate-based bath, birnessite-type MnO2 electrodes are directly obtained with no further heat treatment. Moreover, a crystalline/amorphous structural transition is observed as the applied current density is increased up to 50 mA cm(-2).engManganese oxide filmsLithium-ion batteriesEnergy storageSupercapacitorNickelNanocompositeGrapheneElectrodeposition: a versatile, efficient, binder-free and room temperature one-step process to produce MnO2 electrochemical capacitor electrodesjournal article10.1039/c7ra04481j
