High-entropy oxides for energy storage and conversion

Abstract

The escalating demand for energy storage and catalysis devices in the realm of renewable energy applications has witnessed a rapid surge in recent years, with expectations for continued growth in the foreseeable future. High-entropy oxides, characterized by their diverse atomic configurations, offer notable attributes such as entropy stabilization and redox reactivity, thereby fostering heightened research endeavors within the domain of energy storage and catalysis. This review endeavors to elucidate the entropy-driven mechanisms underpinning high-entropy oxides in the context of energy storage and conversion. Subsequently, it provides a comprehensive exposition of the cutting-edge synthesis strategies and methodologies employed in the fabrication of high-entropy oxides. Moreover, recent advancements in the utilization of high-entropy oxides as cathode/anode materials across a spectrum of energy storage devices, including batteries and supercapacitors, as well as in catalytic systems encompassing photocatalysis and electrocatalysis, are expounded upon. In addition, this review addresses the impending challenges and forthcoming prospects associated with high-entropy oxide electrode materials. Ultimately, it endeavors to offer novel insights aimed at informing the design and implementation of high-entropy oxide electrodes for the advancement of next-generation energy storage and conversion.
