High-Entropy Alloys (HEAs) are made up of five or more major components. In addition to the inherent advantages of binary or multiple alloys, HEAs also have the advantages of multifunctional effect, flexible regulation of element components and proportions, and high structural stability. It provides a platform for researchers to adjust the surface catalytic sites and catalytic characteristics by selecting and controlling the key factors. The unique design concept and significant mixing en-tropy effect of High-Entropy Alloys are expected to break through the bottleneck of comprehensive performance of current electrochemical catalytic materials, and provide new power for the design, synthesis, and application of electrochemical catalysts. In this paper, the definition, entropy calcu-lation, structure, and composition characteristics of High-Entropy Alloys are summarized. Secondly, the research progress of High-Entropy Alloys as catalytic materials in hydrogen evolution, oxygen evolution, and other applications is emphasized.
