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

open access: yesAdvanced 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,

Influence of Metal Species and Content of Fe‐Ni‐Poly(heptazine imides) on their Properties as Electrocatalysts for Zinc‐Air Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Iron/nickel‐modified poly(heptazine imides) are efficient, low‐cost bifunctional electrocatalysts for the oxygen reduction and evolution reactions in aqueous zinc–air batteries. Iron enhances oxygen reduction, while nickel single‐atoms deliver oxygen evolution activity comparable to RuO2.

Imidazolium Cation‐Stabilized Interfacial Chemistry for Durable Aqueous Cadmium‐Iodine Batteries

open access: yesAngewandte Chemie, EarlyView.
An aqueous cadmium‐iodine (Cd//I2) battery is constructed through interfacial chemistry regulation. The cadmium anode effectively suppresses parasitic hydrogen evolution and enhances anode stability, while the incorporation of BMIM+ additives anchors polyiodide species, alleviating the polyiodide shuttle effect and reinforcing interfacial robustness ...
