Summary: In recent years, layered oxides have been widely studied as promising cathode materials for sodium-ion batteries. However, complex phase transitions during charge-discharge process negatively impact their electrochemical performance. High-entropy layered oxides, with 2D ion migration channels between layers, show improved cycling performance. This paper reviews the research status of high-entropy layered oxides in sodium-ion batteries, focusing on the connection between high-entropy and layered oxide phase transitions during electrochemical charging and discharging, and summarizes the advantages and challenges of future high-entropy layered materials.

Summary: Low-cost sodium-ion batteries (SIBs) are considered as a potential replacement for lithium-ion batteries, but their practical application is hindered by their low energy density and cyclic performance. Layered transition metal oxides (LTMOs) have emerged as promising cathode materials due to their compact crystal structure, low-cost, and similarities to successful Li-based LTMOs. However, challenges like severe phase transitions, sluggish diffusion kinetics, and interface deterioration need to be addressed for achieving high-performance cathodes. This review provides a comprehensive overview of the modification strategies for Na-based LTMOs and offers insights into the future development of Na-based LTMOs cathodes.
