Unlocking hidden battery mechanistic insights: A novel mechano-electrochemical impedance spectroscopy approach

Other text in scientific journal, 2026

Mechano-electrochemical signals are vital for battery diagnostics but have lacked direct interpretability for chemical experts. Fang et al. introduce mechano-electrochemical impedance spectroscopy (MEIS), a frequency-domain framework that decodes mechanical responses. This technique links mechanical response to electrochemical level ion dynamics, unlocking a powerful, interpretable new dimension for assessing broader energy storage systems.
