Abstract

The consumption of renewable energy sources has seen a rapid and significant increase in the last decade, hence enhancing the need for the prompt progress of an energy storage setup. Advancing the properties of fabricated electrodes might potentially resolve this kind of issue. The perovskite based nanocomposite with carbonations materials has several applications, particularly in energy conversion and storage. Here, a new MgCeO₃/rGO nanocomposite material was fabricated using the hydrothermal method for the energy storage system. In this article, the physical behavior of the synthesized material MgCeO₃/rGO composite were examined through physical as well as electrical properties by electrochemical techniques. In MgCeO₃/rGO composite rGO enhanced the surface area due to redox activity increased. The electrochemical behavior of the MgCeO₃/rGO nanocomposite sample had a specific capacitance (C_s) value (1494.65 F g⁻¹) at 1 A·g⁻¹. Moreover, the fabricated electrode illustrated the best cycle stability after successive 5000th cycle Additionally, enhanced in electrochemical characteristics of prepared MgCeO₃/rGO composite can be attributed to its extensive surface area, negligible resistances and swift flow of electrolyte ions compared to the individual substances. Moreover, in the future, the MgCeO₃/rGO composite, which can be used to fabricate the electrode material, can be used in diverse electrochemical applications as electrode material in storage mechanisms.

储能用钙钛矿基氧化石墨烯纳米材料的合成与表征

在过去十年中，可再生能源的消费迅速而显著地增加，因此加强了对储能装置迅速取得进展的需求。提高制备电极的性能可能会潜在地解决这类问题。钙钛矿基纳米复合材料具有多种应用，特别是在能量转换和存储方面。本文采用水热法制备了一种新型的MgCeO3/rGO纳米复合材料用于储能系统。本文通过电化学技术对合成的MgCeO3/rGO复合材料的物理性能和电学性能进行了表征。在MgCeO3/rGO复合材料中，由于氧化还原活性增加，rGO的表面积增强。在1 a·g−1时，MgCeO3/rGO纳米复合材料样品的电化学行为具有1494.65 F g−1的比电容（Cs）值。此外，制备的MgCeO3/rGO复合材料在连续5000次循环后表现出最佳的循环稳定性。此外，与单个物质相比，制备的MgCeO3/rGO复合材料具有广泛的表面积，可忽略的电阻和快速的电解质离子流动，从而增强了电化学特性。此外，在未来，可用于制造电极材料的MgCeO3/rGO复合材料可作为电极材料用于各种电化学应用中的存储机制。图形抽象

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.
