Investigation on SrCoO3 perovskites for supercapacitor applications.

Perovskite SrCoO₃ material is synthesized using sol-gel method followed by solid state reaction at three different temperatures 700 °C, 800 °C, and 900 °C. The crystalline structure of the material is confirmed by XRD, and the presence of the functional groups is confirmed by FTIR. The electrochemical performance of the material is carried out using a three-electrode system. The material synthesized at 700 °C exhibits a high specific capacity value of 303 C/g at a current density of 1 A/g, and it exhibits 50% capacity retention after 10,000 charge-discharge cycles at 10 A/g.
