摘要：
The extensive use of metal oxide decorated with carbon-based materials for electrochemical energy storing devices has recently attracted considerable attention. The LaCoO3/rGO composite was fabricated for energy storage applications following different various analytical tools. The specific surface area of the LaCoO3@rGO composite 88 m2/g which was greater than the individual counterparts. The nanocomposite exhibited outstanding electrochemical behavior with a specific capacitance of 1530 F/g at 1 A/g, found from galvanostatic charge-discharge plots, which showed stability after 5000 cycles with a low charge transfer resistance of 0.19 Omega cm2 found from Nyquist plot. The addition of rGO into perovskites improved their electrochemical efficiency by providing a larger surface area and active sites and improved the conductivity. Moreover, the excellent stability of the composite shows it has potential to be used for next generation supercapacitor devices.
