Summary: Perovskite materials SrFexCo1-xO3-delta (SCF-x, x = 0.2, 0.5, 0.8) were synthesized by sol-gel combustion and studied as electrode materials for supercapacitors. The synthesized samples were characterized using X-ray Diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), Raman spectroscopy, Scanning Electron Microscope (SEM), and Energy Dispersive X-ray Spectroscopy (EDS). Substitution in the perovskite structure affected the oxygen vacancy concentration and changed the electrochemical properties. SCF-0.8 exhibited the highest specific capacitance (433 F center dot g(-1)) at 2 A center dot g(-1) current density due to its morphology, crystal structure, and higher oxygen vacancy concentration. The electrochemical stability of SCF-0.8 was tested and it retained around 60% of its initial specific capacitance after 2500 charge-discharge cycles.
