Abstract

Nickel-cobalt oxide is a type of transition metal oxide which is extensively accredited as an outstanding electrode material for application in supercapacitors. It outperforms single components in terms of superior specific capacitance and incredible rate capability. In this perspective, porous NixCo3-xO4 nanowires have been effectively engineered using a hydrothermal apprroach followed by calcination. The resulting porous NixCo3-xO4 nanowire electrodes display significant properties. They achieve a better specific capacitance (1191.4 F/g) at 1 A/g with superior cycling stability. Interestingly, the NF does not only act as 3Dmacroporousconductive current collector but also as a source of Ni for the formation of NixCo3-xO4 nanowire. These exceptional properties position porous NixCo3-xO4 nanowires as a highly capable prospect for energy storage applications.
