High-entropy materials: Synthesis and energy storage applications

Abstract

With the rapid development of energy storage technology, the demand for high-performance energy storage materials continue to grow considerably. High-entropy materials (HEMs), as a novel multi-component material system, have demonstrated broad application prospects in the field of energy storage in recent years. This review is dedicated to comprehensively summarizing the concepts and definitions, synthesis methods and application progress of HEMs in energy storage. Firstly, the concepts and definitions of HEMs are expounded, and the newly emerged high-entropy concepts are briefly introduced. Subsequently, various synthesis methods of HEMs are discussed in-depth, and the advantages and disadvantages of each method are meticulously analyzed. In terms of energy storage applications, this review focuses on the application of HEMs in batteries and supercapacitors, covering cathodes, anodes and electrolyte materials. In addition, the potential applications of HEMs in other fields such as photocatalysis, electrocatalysis, thermal catalysis and thermoelectricity are briefly discussed. Finally, the future development direction of HEMs is prospected in order to provide reference and inspiration for the further research and application of HEMs.
