Dual Action of Zeolite and Polyethylene Glycol Enables Robust and Ion-Conductive Poly(vinyl alcohol)-Based Hydrogel Electrolytes for Stable Zinc-Ion Batteries
Zinc-ion batteries (ZIBs) are promising candidates for large-scale energy storage owing to their high theoretical capacity, low cost, environmental benignity, and intrinsic safety. However, their practical application remains limited by interfacial side reactions at the Zn anode and insufficient electrolyte stability...
