Aqueous Electrolyte With Weak Hydrogen Bonds for Four‐Electron Zinc–Iodine Battery Operates in a Wide Temperature Range
Hunan University · State Key Laboratory of Chemobiosensing and Chemometrics
Abstract
Abstract In the pursuit of high‐performance energy storage systems, four‐electron zinc–iodine aqueous batteries (4eZIBs) with successive I − /I 2 /I + redox couples are appealing for their potential to deliver high energy density and resource abundance. However, susceptibility of positive valence I + to hydrolysis and instability of Zn plating/stripping in conventional aqueous electrolyte pose significant challenges. In response, polyethylene glycol (PEG 200) is introduced as co‐solvent in 2 m ZnCl 2 aqueous solution to design a wide temperature electrolyte. Through a comprehensive investigation combining spectroscopic characterizations and theoretical simulations, it is elucidated that PEG disrupts the…
