Application of SrFeO3 perovskite as electrode material for supercapacitor and investigation of Co-doping effect on the B-site

Energy storage by supercapacitors with short charging time and high power density is one of the types of electrochemical storage systems. Perovskite oxides have been significantly investigated as promising materials for energy storage in electrochemical systems. In this study, three perovskites, SrFeO3, SrCoO3 , and SrCo0.5Fe0.5O3, were prepared using the sol-gel method and used as supercapacitor electrode materials.
