© 2024 Elsevier LtdThe development of supercritical CO2 Brayton cycle technology has made significant progress over the past decades. However, the pure CO2 has certain limitations in aspects such as heat transfer performance, cycle efficiency, and working temperature range. To overcome these limitations, CO2-based mixtures have emerged as a promising technology, already extensively applied in research without altering the basic system configuration. Understanding the research progress in this emerging field is crucial for future studies. This article first reviews the current research status and challenges faced by S-CO2 power cycles. Then, the three aspects are analyzed, selection of additives, calculation methods for mixture parameters, and application of heat sources. The article summarizes the commonly used additives in existing literature, outlines the principles for selecting additives, and analyzes the current research in cycles. This review will be a valuable addition to understanding recent advancements in CO2 power cycle.
