Abstract | The successive ionic layer adsorption and reaction (SILAR) technique was adapted to produce the interconnected complex network of BaO:MgO nanorods on a flexible stainless-steel (SS) substrate surface. The phase and surface morphology of the BaO:MgO electrode were examined from the X-ray diffraction and scanning electron microscopy measurements, respectively, which endowed electrochemical specific capacitance (SC) of 528.77 F/g at a 2 mV/s scan rate with great rate capability and cycling performance of 94.33 % over 5000 cyclic voltammetry cycles. Fabricated BaO:MgO//AC asymmetric solid-state supercapacitor device, using polyvinyl alcohol and potassium hydroxide gel as an electrolyte, demonstrated distinctive energy storage performance, i.e., a specific capacitance (SC) of 259.07 F/g with an energy density of 57.27 Wh/kg and a power density of 2.34 kW/kg at a current density of 4 mA/cm(2). The results demonstrated the facile method for synthesizing a spherical nanorod network of BaO:MgO and made them promising electrode materials for energy storage applications. The use of a solid-state supercapacitor device to illuminate an LED demonstrated the commercial feasibility of both the materials utilized and the design type. |
