Solvothermal synthesis of Fe3S4@graphene composite electrode materials for energy storage
Source abstract
Abstract
Necessity of novel energy storage devices extensively increased due to consumption of high power in various devices. To address the issues, in this report, we are addressing with a composite Iron Sulfide/reduced Graphene Oxide (Fe3S4/rGO) synthesized using the standard solvothermal method. X-ray diffraction and Field Emission Scanning Electron Microscope analysis results confirmed that Face-Centered cubic crystal structure of Fe3S4 and rGO’s surface is decorated with a mean diameter of < 50 nm Fe3S4 respectively. Transmission Electron Microscopy images show further evidence that dispersed Fe3S4 on the rGO surface. Fe3S4/rGO exhibits specific capacitance of 560 F/g than its individual counterparts (Fe3S4 = 200 F/g and rGO = 145 F/g) at 1 A/g of current density and maximum cyclic stability of 91% capacitance retention after 2000 cycles that may be the influence of synergy between the composite materials.
