Recent advances in high-entropy metal sulfides, selenides, and phosphides for use in lithium/sodium-ion batteries

Abstract

The high-entropy concept has driven technological innovation in the field of rechargeable batteries, providing novel solutions for the design of material composition, structure, and electronic properties. This review systematically summarizes the development and application of high-entropy sulfides, selenides, and phosphides as anode materials in rechargeable batteries. These materials benefit from advantages such as tunable composition, structural diversity, high conductivity, and entropy-driven stability. It offers a systematic overview of the current research status and challenges to these high-entropy anode materials, focusing on synthesis strategies, characterization, structural features, electrical properties, multi-element synergism, and electrochemical performances. Future research directions, persistent challenges, and potential methodologies are identified, aiming to accelerate the fundamental understanding and practical applications of high-entropy sulfides, selenides, and phosphides in energy storage.
