Free-standing NiCoSe₂ nanostructure on Ni foam via electrodeposition as high-performance asymmetric supercapacitor electrode

Designing a high-energy-density and power-density electrode for supercapacitors has become an increasingly important concept in the energy storage community. In this article, NiCoSe2 nanostructures were electrodeposited on nickel (Ni) foam and directly used as electrodes for supercapacitors. The effect on the morphology and electrochemical performance of NiCoSe2 prepared under different scan rates was measured through scanning electron...
