摘要

Perovskites show significant potential in addressing the global energy crises and assessing the long-term durability of pseudocapacitive materials is critical. So, doping has proven effective in improving materials’ cyclic stability and capacitive properties. In this study, Ce doping significantly enhanced the electrochemical characteristics of  SrTiO3 electrode. The remarkable electrochemical properties of Ce-doped SrTiO3 can be attributed to improved characteristics, such as its crystal structure, morphology and surface area. The specific capacitance of pure SrTiO3 and Ce-doped SrTiO3 was found to be 1071 F/g and 1339 F/g. The Nyquist plot found charge transfer resistance of 0.1 Ω. After 50 h of undergoing 5000th cycles, the material exhibited electrical stability, indicating that its structure remained unchanged. The Ce-doped SrTiO3 electrode material with improved performance showed it has to be utilized for next generation energy storing technology.
