Novel composite of ZnMoO4/Ni(OH)2 as an electrode material for enhanced performance in energy-storage applications

Abstract

Hydrothermally synthesized micro-flower structure of ZnMoO4 and nano-flower structure of Ni(OH)2 were employed as an electrode materials for supercapacitors. Composites of ZnMoO4 anchored with Ni(OH)2 were prepared in different ratios (9 : 1, 8 : 2, 7 : 3) and their electrochemical performance was analyzed using cyclic voltammetry (CV), galvanostatic charge and discharge (GCD) analysis, and stability studies. The Z/N-2 composite with a weight ratio of ZMO : NOH of 8 : 2, displayed a higher specific capacitance of 662 F g−1 at a current density of 1 A g−1. During the stability study, the composite (Z/N-2) exhibited a 73.4% retention of its capacitance at a current density of 5 A g−1, indicating its excellent stability at a high current density after 4000 cycles. The enhanced performance of the Z/N-2 composite, resulting from the good conductivity of ZnMoO4 and the battery-type charge-storage behavior of Ni(OH)2, paves way for its development as a robust electrode material for supercapacitors.
