Hierarchical Fluorinated Polymer Separator Design Mitigating Bilateral Ionic Crosstalk in Aqueous Batteries

Advanced Energy Materials, EarlyView.
Aqueous zinc‐ion batteries suffer from rapid decay under practical conditions due to bilateral Zn2+/Mn2+ ionic crosstalk, a system‐level failure mechanism. We develop a hierarchical fluorinated polymer separator that regulates ion fluxes and stabilizes both electrodes simultaneously. This strategy enables extended cycle life while maintaining capacity,
