Electrodeposition: a versatile, efficient, binder-free and room temperature one-step process to produce MnO2 electrochemical capacitor electrodesElectronic supplementary information (ESI) available: SEM images and XRD. See DOI: 10.1039/c7ra04481j

The use of room temperature cathodic electrodeposition to produce MnO 2 electrochemical capacitor electrodes is demonstrated. By employing a permanganate-based bath, birnessite-type MnO 2 electrodes are directly obtained with no further heat treatment. Moreover, a crystalline/amorphous structural tr...

description The use of room temperature cathodic electrodeposition to produce MnO 2 electrochemical capacitor electrodes is demonstrated. By employing a permanganate-based bath, birnessite-type MnO 2 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 . The use of room temperature cathodic electrodeposition to produce MnO 2 electrochemical capacitor electrodes is demonstrated.
