Suppressing concentration polarization in lithium battery composite polymer electrolytes via piezo-assisted electromechanical coupling effect

Nature Communications, Published online: 30 April 2026; doi:10.1038/s41467-026-72527-0 Concentration polarization limits cycling stability of cells at high currents. Here, authors propose a mechanical-electrochemical conversion strategy by constructing a piezo electrolyte that actively utilizes the unavoidable volume fluctuation of lithium metal to minimize concentration polarization.
