Fabrication schemes and images of a CNT/MnO2 hybrid nanostructured electrode. a Schematic illustration of the fabrication of a coaxial-shaped CNT/MnO2 electrode with a Ni fiber as the current corrector. b Line-scan EDS data on a cross-section image of a typical CNT/MnO2 hybrid nanostructured electrode (9-layered MnO2 and 8-layered CNTs) showing C (carbon, red line), Mn (manganese, green line), and O (oxygen, blue line) atoms (scale bar, 2.5 μm). c EDS elemental mappings for C, Mn, and O, respectively (scale bar, 3 μm). d A cross-sectional SEM image (scale bar, 2 μm) obtained by polishing with a cross-section polisher. e Schematic illustration of the configuration of the CNT/MnO2 hybrid nanostructures. f A cross-sectional SEM image of fracture end area of the CNT/MnO2 hybrid nanostructures (scale bar, 250 nm)
