Abstract

Electrochemical impedance spectroscopy (EIS), as a non-invasive and non-destructive diagnostic technique, has shown unique advantages and significant potential in lithium-ion battery state monitoring. However, its traditional steady-state methods face substantial limitations under the non-stationary operating conditions commonly encountered in practical applications. To overcome these challenges, dynamic electrochemical impedance spectroscopy (DEIS) has emerged as a critical tool due to its real-time monitoring capabilities. This review provides a comprehensive overview of recent advances in DEIS for lithium-ion battery state monitoring, starting with an in-depth explanation of its working principles and a comparison with conventional EIS to highlight their respective advantages. Analytical methodologies for EIS are then introduced to establish a theoretical foundation for the discussion of subsequent findings. The review emphasizes recent breakthroughs achieved using DEIS, particularly in elucidating charge transfer dynamics during charge–discharge cycles, detecting lithium plating at the anode, and monitoring internal temperature variations within batteries. It further explores the potential of DEIS in battery health prediction, demonstrating its role in enhancing the accuracy and reliability of battery management systems. Finally, the review concludes with a forward-looking perspective on the future development of DEIS, underscoring its transformative potential in advancing battery diagnostics and management technologies.

动态电化学阻抗谱:锂离子电池状态评估的前沿应用方法
电化学阻抗谱(EIS)作为一种无创、无损的诊断技术,在锂离子电池状态监测中显示出独特的优势和巨大的潜力。然而,在实际应用中经常遇到的非平稳工况下,传统的稳态方法面临着很大的局限性。为了克服这些挑战,动态电化学阻抗谱(DEIS)因其实时监测能力而成为一种关键工具。本文全面概述了用于锂离子电池状态监测的DEIS的最新进展,首先深入解释了其工作原理,并与传统EIS进行了比较,以突出各自的优势。然后介绍环境影响报告书的分析方法,为讨论后续发现奠定理论基础。这篇综述强调了最近使用DEIS取得的突破,特别是在阐明充放电循环过程中的电荷转移动力学、检测阳极的锂电镀以及监测电池内部温度变化方面。进一步探讨了DEIS在电池健康预测方面的潜力,展示了其在提高电池管理系统的准确性和可靠性方面的作用。最后,对DEIS的未来发展进行了前瞻性的展望,强调了其在推进电池诊断和管理技术方面的变革潜力。
