Abstract
Growing populations and development led to a higher utilization of fossil fuels and more CO2 emissions; which prompted researchers to look for pollution-free energy sources and improved energy-storage technologies. Supercapacitors (SCs) are thought to be the most advanced available energy-storage technology and are improving day by day via modifying the electrode composition. In this work, we described the hydrothermal production of SrCeO3/RGO nanocomposite as an effective and high-performance electrode material for SCs. Different approaches were adopted to look at the structural features along with the electrochemical behaviors of the prepared nanocomposite. X-ray structural analysis data and surface analysis showed that the nanocomposite had a pure crystalline phase and enhanced surface area. SrCeO3/RGO nanocomposite possessed a specific capacitance of 1359.9 F/g at 1 A/g, while it was 653.1 F/g for pure SrCeO3 electrode. The nanocomposite showed a small decrease in its polarization curve area following the 6000th cycle of the stability test. Additionally, SrCeO3 and SrCeO3/RGO nanocomposite exhibited specific energy of 28.7 and 63.5 Wh/kg at 1 A/g value with specific power of 281.5 and 290.1 W/kg, respectively. Numerous findings demonstrated that the enhanced ion/electron mobility and electric conductivity of nanocomposite lead to a rapid charge-storing approach and significantly boost electrochemical performance. The exceptional functionality of the SrCeO3/RGO nanocomposite demonstrated its favorable potential for the future generation of energy storage by reducing reliance on materials with a spinel-like structure.
期刊介绍:
The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
