Vertically aligned TiO2 nanotubes: Highly stable electrochemical supercapacitor
The ordered arrays of nanostructure with vertically aligned tube like structure hold great promise as an electrode material for high-performance energy storage devices. Such binder-free structure of Titanium dioxide (Ti02) has been synthesized by anodization of titanium (Ti) foil. The use of TiO2 nanotube as an electrode material attain a specific capacitance of 207 F g(-1) at 5 mV s(-1) scan rate in 1 M potassium hydroxide (KOH) electrolyte. Extra ordinary cycling performance with 103% capacitance retention of their initial capacitance for 1500 cycles has been achieved, suggests its promising candidate as highly stable electrode material for supercapacitor application.
