Abstract

High-entropy oxides (HEOs), composed of multiple cations, have emerged as potential anode materials for lithium-ion batteries (LIBs) owing to their excellent capacity, outstanding cycling stability, and tunable charge-discharge properties. This study systematically investigates the effects of morphology on the electrochemical performance of HEO anodes. Combining the high-entropy strategy with morphological tuning can effectively improve the electrochemical performance. Herein, (CrFeMnNiCo)₃O₄ HEOs with well-defined nanoparticle (HEO-NP) and yolk-shell (HEO-YS) structures are successfully synthesized. The influence of morphology on the electrochemical performance of HEO-NP and HEO-YS electrodes are systematically examined. HEO-YS with a yolk-shell morphology outperforms HEO-NP, delivering superior capacities of 954 and 650 mAh g^–1 at lithiation-delithiation rates of 50 and 2000 mA g^–1, respectively, along with an impressive capacity retention of 94 % after 250 cycles. The superior rate capability and cycling stability of HEO-YS can be ascribed to its unique yolk-shell structure, which accommodates volume change, mitigates structural strain, and enhances lithium-ion diffusion. These findings provide valuable insights into morphology engineering as a strategy for optimizing the electrochemical performance of HEO anodes for next-generation LIBs.

高性能锂离子电池用蛋黄壳结构（crmnnfeconi）3O4高熵氧化物阳极

由多个阳离子组成的高熵氧化物（HEOs）由于其优异的容量、出色的循环稳定性和可调的充放电性能而成为锂离子电池（LIBs）的潜在负极材料。本研究系统地研究了形貌对HEO阳极电化学性能的影响。将高熵策略与形态调谐相结合可以有效地提高电化学性能。本文成功合成了具有良好定义的纳米颗粒（HEO-NP）和蛋黄壳（HEO-YS）结构的（CrFeMnNiCo）3O4 HEOs。系统地考察了形貌对HEO-NP和HEO-YS电极电化学性能的影响。具有蛋黄壳形态的HEO-YS优于HEO-NP，在50和2000 mA g-1的锂化衰减率下分别提供954和650 mAh g-1的卓越容量，并且在250次循环后容量保持率高达94%。HEO-YS优异的倍率性能和循环稳定性可归因于其独特的蛋黄壳结构，可以适应体积变化，减轻结构应变，增强锂离子的扩散。这些发现为形态学工程作为优化下一代锂离子电池HEO阳极电化学性能的策略提供了有价值的见解。
