Optimized Ba-doped MgSnO₃ as a high-performance electrode material for supercapacitor applications
摘要
Currently, perovskite is used as an electrode material for supercapacitors. Doped perovskite can be used to improve the efficiency of supercapacitors. The Ba-doped (Ba-MgSnO3) and perovskite (MgSnO3) nanomaterial were fabricated using the sol–gel process. The objective of this synthesis was to investigate the capabilities of doped nanomaterials for the applications of SCs. The fabricated material was examined physically and electrochemically through several analysis, such as scanning electron microscopy (SEM), which was used to examine the morphology of MgSnO3 nanoparticles which were improved by doping with transition metal (Barium). For electrochemical analysis, the tests were examined in a 3.0 M KOH electrolyte. When tested at 1 A/g, the Ba-doped MgSnO3 shows the best charge–discharge cyclic behavior, with a remarkable Cs value of almost 874.6 F/g. The solution resistance Rs (1.16 Ω) were founded using EIS graph. The sol–gel process of fabricated perovskite and their doping with Ba improved its electrochemical characteristics, making it suitable for SC applications and a potential candidate for future energy storage devices.
