Abstract


  • Here, we report the fabrication of self-organized titania (TiO2) nanotube array supercapacitor

    electrodes through controlled phase transformation of TiO2, with aerial capacitances as high as

    2.6 mF cm-2, which far exceeds the values so far reported in the literature. The role of phase

    transformation in the electrochemical charge–discharge behaviour of nanocrystalline TiO2

    nanotubes is investigated and discussed in detail. The ease of synthesis and the exceptional

    electrochemical properties make these nanotube arrays an alternative candidate for use in energy

    storage devices
