Supercapacitor Electrode Material Based on Nickel Vanadium Oxide

Nickel vanadium oxide with rod like architecture has been hydrothermally synthesized and electrochemically characterized as electrode material for supercapacitor application. The maximum specific capacitance of 412 and 297 F/g was achieved respectively at 2 mV/s and 3 A/g for the nickel vanadium oxide electrode in 1 M LiCl electrolyte. The NVO electrode also responded with high energy density of 165 Wh/kg at the power density of 3015 W/kg accompanied by 89.5% specific capacitance retention over 500 consecutive CV cycles at 2 mV/S.
