Graded‐Interface Dual‐Environment Hydrogel‐Polymer Electrolyte for Stabilized Anode and Sustained Cathode Kinetics in Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A graded‐interface hydrogel‐polymer electrolyte decouples water activity to simultaneously stabilize the Zn anode and sustain cathode kinetics. The flexible design supports dendrite‐free cycling over 1600 h, high capacity in both MnO2 and V2O5 full cells, and stable pouch‐cell performance under bending, resolving the fundamental water conflict in ...
