Rechargeable metal-ion batteries,such as lithium-ion batteries(LIBs)and sodium-ion batteries(SIBs),have raised more attention because of the large demand for energy storage solutions.Undoubtedly,elec-trode materials and electrolytes are key parts of batteries,exhibiting critical influence on the reversible capacity and span life of the metal-ion battery.Nonetheless,researchers commonly express concerns regarding the stability of both electrodes and electrolytes.Given its commendable stability attributes,high-entropy materials have garnered widespread acclaim and have been applied in many fields since their inception,notably in energy storage.However,while certain high-entropy designs have achieved substantial breakthroughs,some have failed to meet anticipated outcomes within the high energy den-sity energy storage materials.Moreover,there is a lack of comprehensive summary research on the cor-responding mechanisms and design principles of high-entropy designs.This review examines the current high-entropy designs for cathodes,anodes,and electrolytes,aiming to summarize the design principle,potential mechanisms,and electrochemical performance.We focus on their structural characteristics,interface characteristics,and prospective development trends.At last,we provide a fair evaluation along-side succinct development suggestions.
