TY - JOUR TI - Application of $SrFeO_3$ perovskite as electrode material for supercapacitor and investigation of Co-doping effect on the B-site AB - 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, $SrFeO_3, SrCoO_3, and SrCo_{0.5}Fe_{0.5}O_3$, were prepared using the sol-gel method and used as supercapacitor electrode materials. In fact, in this research, two consecutive elements (Fe, Co) from the periodic table that differ by one unit in atomic number are placed in the perovskite structure to study their electrochemical properties for use in supercapacitors. From the obtained results, it was found that Co doping with a ratio of 1/1 (Co/Fe) at B site of $SrFeO_3$ reduced the specific capacitance from 101.687 $F g^{–1}$ to 60.912 $F g^{–1}$ at a scan rate of 10 $mV s^{–1}$. Also, the specific capacitance of $SrCoO_3$ decreased from 68.639 $F g^{–1}$ to 60.912 $F g^{–1}$ at the same substitution rate at B site.
