Stabilized Rechargeable Aqueous Zinc Batteries Using Ethylene Glycol as Water Blocker

evolution and enables dendrite-free Zn plating/stripping. Accordingly, a Zn//PQ-MCT (phenanthrenequinone macrocyclic trimer) full cell with such electrolyte exhibits a very long cycling life (more than 8000 cycles). Furthermore, this EG-based aqueous electrolyte is non-flammable and inexpensive and prevents evaporation of water when open to the atmosphere, endowing aqueous Zn batteries with excellent safety performance and easy operability in practical applications.
