Synthesis of nis anchored graphenenanocomposites: high performance supercapacitor electrode material

Reduced Graphene Oxide (rGO) based Nickel Sulfide (NiS) anchor nanocomposites were developed via hydrothermal approach. We have investigated the effect of different concentration of thioglycolic acid on graphene oxide reduction. More the thioglycolic acid present with the graphene oxide, the reduction is more and high electrochemical activity is also achieved by the composite having high concentration of sulfur. We have achieved specific capacitance of 109.37 F/g at 2.5 A/g for the composite rGO-NiS using 2.7 ml of thioglycolic acid. Energy density and power density of this composites show9.72Wh/kg and 1000W/kg, respectively.
