Abstract
With the growing demand for sustainable energy, portable energy storage systems have become increasingly critical. Among them, the development of rechargeable batteries is primarily driven by breakthroughs in electrode materials. High-entropy materials, composed of five or more metallic elements, have emerged as promising anode candidates for Li+/Na+/K+ batteries due to their large compositional space, entropy stabilization effect, tunable electronic structures, and high theoretical capacities. However, the complex interplay among phase transformations, structural evolution, and electrochemical properties in high-entropy anode materials (HEAMs) remains poorly understood, limiting their broader application. This review provides a comprehensive summary of recent advances in HEAMs for Li+/Na+/K+ batteries, with a particular emphasis on elemental design and microscopic morphology regulation. The interconnections among elemental design, structural control, and electrochemical properties are critically analyzed. Key challenges and future directions are also highlighted to guide the rational design and practical implementation of next-generation HEAMs.
