The oxygen-deficient perovskite oxide Sr2FeCoO6-delta was effectively prepared through a simple wet chemical method and thermal processing, exhibiting remarkable electrochemical properties suitable for supercapacitors with good cycling stability.
Oxygen-deficient perovskite oxides manifest capability of multi-functional application with remarkable physical and chemical properties. In the present study, Sr2FeCoO6-delta, an oxygen-deficient perovskite has been effectively prepared through easy wet chemical method followed by thermal processing at 1000 degrees C temperature. The Rietveld refinement of Sr2FeCoO6-delta, X-ray diffraction pattern indicates the structure of the cubic phase of Sr2FeCoO6-delta with Pm (3) over barm symmetry. The super-capacitive behavior of Sr2FeCoO6-delta electrode; investigated first time and electrochemical analysis technique performed using potassium hydroxide electrolyte solution show magnificent outcomes, i.e., the specific capacitance 263 F/g at 1 A/g. Further, electrode stability has been tested by performing 3000 charging-discharging cycles and 57% retention was attained, which indicates the electrode capability for energy storage application.
