The porous anatase TiO 2 nanoparticles were synthesized by a facile hydrothermal method and characterized by scanning electronic microscopy (SEM), transmission electronic microscopy (TEM) and powder X-ray diffraction (XRD). A non-aqueous hybrid supercapacitorwith the as-prepared TiO 2 nanoparticles anode and activated carbon (AC, BP-2000) cathode was fabricated and investigated electrochemically. The results showed that the hybrid supercapacitor with the optimal mass ratio 1:2 of AC to TiO 2 delivers a specific capacitance of 48 F g -1 at a cur...
