High-entropy materials for electrochemical energy storage devices

Abstract

Single phased, high-entropy materials (HEMs) have yielded new advancements as energy storage materials. The mixing of manifold elements in a single lattice has been found to induce synergistic effects leading to superior physicochemical properties. In this review, we summarize recent advances of HEMs in energy storage applications such as metal-ion batteries, supercapacitors, and fuel cells. We begin with defining HE materials (HEMs) and discussion of the synthetic methods and characterization techniques appropriate for evaluating HEMs at various length scales. We also discuss the application of a wide variety of HEMs, including HE alloys, oxides, chalcogenides, Prussian blue analogues, and sodium super ionic conductor (NASICON) materials in energy storage systems. Finally, advantages, challenges, and future perspectives of HEMs in energy storage systems are discussed.
