“…This HEA demonstrated a high ICE of 91% and a substantial capacity exceeding 1448 mAh g −1 . [43] HES has been documented to enhance electrochemical performance as a result of its elevated electrical conductivity and lithium/sodium ion diffusion coefficient, as well as its highentropy stabilized structure during the conversion process and high capacity retention (Figure 4f, g). [44] Consequently, the utilization of HES yields a discharge capacity of 1358.4 mAh g −1 , accompanied by a low ICE of 66.5%.…”

The low energy density, safety concerns, and high cost associated with conventional lithium‐ion batteries pose challenges in meeting the growing demands of emerging applications. While lithiumsulfur batteries (LSBs) offer high specific capacity, their commercial viability is hindered by the prevalent issue of shuttle effects. Furthermore, the potential of solid‐state lithium batteries is constrained by the suboptimal ionic conductivity and significant interphase problems. High‐entropy materials (HEMs) have emerged as a strategic approach for the development of innovative materials possessing exceptional properties. In recent times, some studies have been undertaken to explore the potential of HEMs in lithium‐based rechargeable batteries, showcasing their favorable characteristics. This work provides a comprehensive overview of the impact of various factors associated with HEM materials, encompassing elements, structure, and morphology, on the reversibility of reactions and cycling stability. This work also presents an analysis of the effects of elements and morphology on the properties of HEMs in LSBs, which can trap soluble lithium polysulfides and enhance reaction kinetics. Additionally, the work provides an overview of high‐entropy electrolytes, including both solid‐state and non‐aqueous liquid electrolytes. Furthermore, the research outlines future research directions aimed at investigating more efficient HEMs and enhancing the overall performance of lithium‐based rechargeable batteries.

“…Although the thermodynamic term ''high entropy'' is always highlighted in HEAs and related research, the success of synthesizing HEAs heavily relies on kinetics control over mixing atoms of different elements, crystallizing the homogeneously mixed atoms, and minimizing the diffusion of atoms in HEAs to avoid phase segregation. In the past five years, HEA research has predominantly focused on This journal is © The Royal Society of Chemistry 2024 synthesizing HEA nanoparticles and exploring their applications in energy-related fields, including catalysis, [6][7][8][9][10][11][12][13][14][15] electrochemical energy storage, 11,[16][17][18][19][20] and light harvesting and conversion. [21][22][23][24][25][26] The emergence of HEA nanomaterials and their promising properties have attracted extensive attention and resulted in some review articles primarily focused on catalysis.…”

“…However, the HEO nanoparticle electrodes for LIBs reported in previous works were mostly prepared by ball milling or hydrothermal methods. 20,21 The nanoparticle size distributions by these traditional top-down methods can be hardly minimized down below 100 nm. Moreover, the extra heat produced during ball milling may undermine some potential active structures.…”
