电池的“心跳”：用压力解开电化学的奥秘| Battery Brew 4

本期节目深入探讨：力学-电化学阻抗谱（Mechano-Electrochemical Impedance Spectroscopy, MEIS）技术——一种通过测量电池内部压力波动来“听诊”电池健康的新方法。电池不仅是电化学系统，更是复杂的力化学系统：锂离子嵌入/脱出会导致电极材料膨胀收缩，像“呼吸”一样产生微观应力。> 内容基于Ruqing Fang、Juner Zhu等人2025年最新发表在《Joule》上的研究：Mechano-Electrochemical Impedance Spectroscopy: Experimentation, Interpretation, and Application作者：Ruqing Fang, Wei Li, Royal C. Ihuaenyi, Junning Jiao, Martin Z. Bazant, Juner ZhuDOI: 10.1016/j.joule.2025.XX.XXXX（Published online, December 17, 2025）> MEIS受传统电化学阻抗谱（EIS）启发，将电流扰动与压力响应结合，提供频率域内对电池力学-电化学耦合的独特洞察，非破坏性且成本低廉，潜力巨大。感谢收听！更多电池前沿论文&解读，探索X账号：@[EKL_Batteries](x.com)前往小宇宙评论区与主播互动
