Highly Exposed Nickel Cobalt Sulfide-rGO Nanoporous Structures: an Advanced Energy Storage Electrode Material

Abstract

Uncontrollable diffusion and associated destruction rate have paralyzed the generation of robust nanostructured porous metal sulfides till date. Here we reported a robust and porous NiCo2S4 nanostructure grown on graphene oxide using a facile synthesis method. Produced ultrathin NiCo2S4 nanosheets contained broad range of nanopores and their graphene backbone enhanced the surface area as well as conductivity to the whole matrix. Advantages of the synthesis method were evaluated with supercapacitor efficiency; this highly porous and exposed nanocomposites delivered high capacitance of 1527 F/g at 10 mV/s in 1.0 M KOH. Such a high capacitive nanomaterial electrode coupled with the graphene-single wall carbon nanohorns heterostructures, provided maximum energy of 60.9 Wh/kg at 1.4 kW/kg power density, proposing the merits of current synthesis method and their applications in progressive electrochemical energy storage/conversion devices.
