Abstract

Layered transition metal oxide (LTMO) cathode materials of sodium‐ion batteries (SIBs) have shown great potential in large‐scale energy storage applications owing to their distinctive periodic layered structure and 2D ion diffusion channels. However, several challenges have hindered their widespread application, including phase transition complexities, interface instability, and susceptibility to air exposure. Fortunately, an impactful solution has emerged in the form of a high‐entropy doping strategy employed in energy storage research. Through the implementation of high‐entropy doping, LTMOs can overcome the aforementioned limitations, thereby elevating LTMO materials to a highly competitive and attractive option for next‐generation cathodes of SIBs. Thus, a comprehensive overview of the origins, definition, and characteristics of high‐entropy doping is provided. Additionally, the challenges associated with LTMOs in SIBs are explored, and discussed various modification methods to address these challenges. This review places significant emphasis on conducting a thorough analysis of the research advancements about high‐entropy LTMOs utilized in SIBs. Furthermore, a meticulous assessment of the future development trajectory is undertaken, heralding valuable research insights for the design and synthesis of advanced energy storage materials.

层状过渡金属氧化物负极材料中的高熵策略在高能量、长循环寿命钠离子电池中的应用进展与展望
钠离子电池(SIB)的层状过渡金属氧化物(LTMO)阴极材料因其独特的周期性层状结构和二维离子扩散通道而在大规模储能应用中显示出巨大的潜力。然而,一些挑战阻碍了它们的广泛应用,包括相变复杂性、界面不稳定性和易受空气暴露影响。幸运的是,一种有影响力的解决方案已经出现,那就是在储能研究中采用高熵掺杂策略。通过实施高熵掺杂,LTMO 可以克服上述限制,从而将 LTMO 材料提升为极具竞争力和吸引力的下一代 SIB 阴极选择。因此,本文全面概述了高熵掺杂的起源、定义和特点。此外,还探讨了在 SIB 中使用 LTMOs 所面临的挑战,并讨论了应对这些挑战的各种改性方法。本综述的重点是对 SIB 中使用的高熵 LTMO 的研究进展进行全面分析。此外,还对未来的发展轨迹进行了细致的评估,为设计和合成先进的储能材料提供了宝贵的研究启示。

期刊介绍: ACS Macro Letters publishes research in all areas of contemporary soft matter science in which macromolecules play a key role, including nanotechnology, self-assembly, supramolecular chemistry, biomaterials, energy generation and storage, and renewable/sustainable materials. Submissions to ACS Macro Letters should justify clearly the rapid disclosure of the key elements of the study. The scope of the journal includes high-impact research of broad interest in all areas of polymer science and engineering, including cross-disciplinary research that interfaces with polymer science. With the launch of ACS Macro Letters, all Communications that were formerly published in Macromolecules and Biomacromolecules will be published as Letters in ACS Macro Letters.
