High-Entropy Electrode Materials: Synthesis, Properties and Outlook

Nano-Micro Letters, Год журнала: 2024, Номер 17(1)

Опубликована: Сен. 27, 2024

Abstract High-entropy materials represent a new category of high-performance materials, first proposed in 2004 and extensively investigated by researchers over the past two decades. The definition high-entropy has continuously evolved. In last ten years, discovery an increasing number led to significant advancements their utilization energy storage, electrocatalysis, related domains, accompanied rise techniques for fabricating electrode materials. Recently, research emphasis shifted from solely improving performance toward exploring reaction mechanisms adopting cleaner preparation approaches. However, current remains relatively vague, method is based on single metal/low- or medium-entropy It should be noted that not all methods applicable can directly applied this review, development are briefly reviewed. Subsequently, classification presented, followed discussion applications storage catalysis perspective synthesis methods. Finally, evaluation advantages disadvantages various production process different provided, along with proposal potential future directions

In Situ Cyclized Polyacrylonitrile Coating: Key to Stabilizing Porous High‐Entropy Oxide Anodes for High‐Performance Lithium‐Ion Batteries

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Авг. 23, 2024

Abstract High‐entropy oxides (HEOs) composed of multiple metal elements have attracted great attention as anode materials for lithium‐ion batteries (LIBs) due to the synergistic effects various species. However, practical applications HEOs are still plagued by poor conductivity, unstable solid electrolyte interphase (SEI) and cycling stability. Herein, nanosized (FeCoNiCrMn) 3 O 4 HEO (NHEO) is prepared successfully NaCl‐assisted mechanical ball‐milling strategy. Novelly, polyacrylonitrile (PAN) used binder then in situ thermochemically cyclized construct a PAN (cPAN) outer layer onto NHEO (NHEO‐cPAN). The formed cPAN coating not only improves electrical but also reinforces structural interfacial stability, thereby, resulted NHEO‐cPAN electrode exhibits significantly enhanced rate cyclic performance. Specifically, NHEO‐PAN500 delivers high reversible capacity 560 mAh g −1 at 5 A high‐capacity retention 83% over 800 cycles . Furthermore, evolution electrochemical behavior NHEO‐PAN during discharge/charge systematically investigated operando X‐ray diffraction, impedance spectroscopy ex high‐resolution transmission electron microscopy. Therefore, this work provides new insights into engineering high‐performance materials, potentially enlightening HEO‐based LIBs.
