    This work is centered on the synthesis and physical properties of AgMnWO₃ as superior energy storage electrodes on graphene scaffolds. As the search for higher efficiency of the energy storage systems advancing most of the conventional systems are challenged by a plethora of time-optimal parameters including stability, rate capability and energy density. AgMnWO₃ has also been identified to have preferable electrochemical performance; hence, would boost the supercapacitors’ performance only if incorporated with graphite. The AgMnWO₃/rGO nanocomposites will be synthesized by hydrothermal process. The surface characteristics and structural compositions of the composites will be examined by techniques such as Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD). Electrochemical characterization using EIS, GCD and CV would be used to ascertain the main functional attribute like the specific capacitance, energy density, the charge transport capability. This preparation techno will be better equipped with graphene in AgMnWO3 and thereby provide the study with more comprehensive analysis of energy storage. Supercapacitors are advanced through the studies on super substrate graphene as well as AgMnWO3, getting relatively higher energy density than that of batteries. This material comes in handy in scenarios like energy storage in renewable power or efficiently integrating graphene composites within a manufacturing process across electric vehicles enhanced strength not to mention the conductivity in energy storage. The summary of investigations of AgMnWO3/rGO composites will shed light on the necessity of classical materials. Any such information that is considered useful to progress with future, sustainable technologies for high-energy storage.
