Abstract
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.
