Electrochemical properties of TiO _x /rGO composite as an electrode for supercapacitors.

ABSTRACT: Transition metal oxides are known as the active materials for capacitors. As a class of transition metal oxide, Magnéli phase TiO _x is particularly attractive because of its excellent conductivity. This work investigated the electrochemical characteristics of TiO _x and its composite with reduced graphene oxide (rGO). Two types of TiO _x , i.e. low and high reduction extent, were employed in this research. Electrochemical impedance spectroscopy revealed that TiO _x with lower reduction extent delivered higher electro-activity and charge transfer resistance at the same time. However, combining 10% of low-reduction state TiO _x and rGO using a simple mixing process delivered a high specific capacitan
