Reconfiguring the Coordination Structure in Deep Eutectic Electrolytes for Enabling Stable Operation of Zinc-Ion Batteries

Highly stable aqueous Zn-ion batteries are of great importance for commercial applications. The challenging issues of interfacial side reactions and rampant dendrite growth cause short circuit and premature failure of aqueous Zn-ion batteries. Herein, a hydrated deep eutectic electrolyte is formulated to tackle such problems, which adopts 1,3-propanediol as a cosolvent. 1,3-Propanediol molecules can enter into the Zn
