Abstract

Abstract: Revolutionary changes in energy storage technology have put forward higher requirements on next‐generation anode materials for lithium‐ion battery. Recently, a new class of materials with complex stoichiometric ratios, high‐entropy oxide (HEO), has gradually emerging into sight and embracing the prosperity. The ideal elemental adjustability and attractive synergistic effect make HEO promising to break through the integrated performance bottleneck of conventional anodes and provide new impetus for the design and development of electrochemical energy storage materials. Here, the research progress of HEO anodes is comprehensively reviewed. The driving force behind phase stability, the role of individual cations, potential mechanisms for controlling properties, as well as state‐of‐the‐art synthetic strategies and modification approaches are critically evaluated. Finally, we envision the future prospects and related challenges in this field, which will bring some enlightening guidance and criteria for researchers to further unlock the mysteries of HEO anodes. Abstract : The ideal elemental adjustability and appealing synergistic effects have led high‐entropy oxide (HEO) to attract growing scientific interest as anode for Li‐ion batteries. This article provides some enlightening guidelines and criteria for further unlocking the mystery of HEO anodes through an overview of their current status and specific descriptions regarding material design and electrochemical behavior.
