The poor ambient ionic transport properties of poly(ethylene oxide) (PEO)-based SPEs can be greatly improved through filler introduction. Metal fluorides are effective in promoting the dissociation lithium salts via establishment Li-F bond. However, too strong interaction would impair fast migration ions. Herein, magnesium aluminum fluoride (MAF) fillers developed. Experimental and simulation results reveal that bond strength could readily altered by changing fluorine vacancy (V

Abstract Aqueous Zn‐ion batteries (AZIBs) are considered a promising candidate for large‐scale energy storage application owing to their high capacity, good safety, low cost, and environmental friendliness. However, the presence of active water leads issues such as corrosion, dendrite growth hydrogen evolution reaction on Zn metal anodes, severely limiting cycle lifetime reversibility AZIBs. To address these challenges, this study introduces simple drop‐casting method deposit composite protective coating 2D titanium carbide (Ti 3 C 2 T x ) MXene polyethyleneimine (PEI) surface foil, i.e., MXene/PEI@Zn. The MXene/PEI contains polar groups −OH that can regulate deposition. Additionally, prevent from directly contacting surface. results show MXene/PEI@Zn anodes over 2600 1100 h at corresponding current density 1 5 mA cm −2 (Areal capacity: mAh ). When paired with V O ·1.6H cathode, it contributes evidently improved full‐cell performance 85% capacity retention after 4800 cycles A g −1 . This work provides new insights into practical design highly reversible anodes.
