🔋 “Water‐in‐Water” Biphasic Electrolyte for Aqueous Zinc‐ion Batteries
📝 الکترولیت دوفازی کاملاً آبی «آب در آب» با قطرههای غنی از دکستران در فاز PEG، شار Zn2+ را تنظیم کرده و چرخهپذیری باتری آبی روی-یون را بهشدت بهبود میدهد.

💡 Novelty & Significance:
The novelty is using a fully aqueous "water-in-water" biphasic electrolyte with dextran-rich droplets in a PEG-rich phase to regulate Zn2+ flux via phase boundaries, rather than solvent chemistry. This buffering of ion accumulation enables stable Zn||Zn cycling for 1100 h and Ah-level pouch cells, demonstrating interfacial electrostatics as a new design principle for aqueous zinc-ion batteries.
