This work emphasizes the procedure with three stages, including a forthright hydrothermal technique for synthesizing composite material of layered MoSe2/rGO and MnO2 nanorods. The developed electrodes explicitly show supercapacitor battery storage capability (i.e., supercapattery), unveiling higher operating potential value energy density. is mainly attributed to structure high surface-to-volume ratio 2D nanosheets, which provide rapid charge aptitudes, enormous active sites, decreased electronic/ionic resistance, rich electron transfer characteristics. MnO2/MoSe2/rGO has an optimum surface area (78.24 m2 g-1) immense microspore (12.9 nm), due construction MoSe2 rGO nanosheets. robust electrochemical characteristics, achieving 950 F g-1 specific capacitance at 1 A current density demonstrating cyclic stability 90% after 10,000 continuous cycles. In addition, asymmetric supercapattery device AC//MnO2/MoSe2/rGO showcased capacity 85.1 153.18 C g-1, as well achieved power 30.2 W h/kg 807 W/kg in 1.8 V. Also, real-time practical tested using two distinct varieties light-emitting diodes offered effective discharge time 14 min. enriched performances composites extensive features may have expanded realm modern materials.
