Wide‐Temperature Aqueous Zinc‐Ion Batteries Dominated by Electrolyte Strategy

Aqueous zinc‐ion batteries (AZIBs) serve as a vital candidate technology for large‐scale energy storage, and the enhancement of their wide‐temperature performance is crucial for expanding application scenarios. However, in extreme environments, they are prone to constraints such as intensified electrode side reactions and electrolyte solidification, which severely limit their practical applications. This review systematically summarizes the major advances in wide‐temperature AZIBs research in recent years, and systematically analyzes the influence of temperature on battery performance from three perspectives: thermodynamics, kinetics, and hydrogen bond regulation. Furthermore, it focuses on electrolyte regulation strategies and gains in‐depth insights into the mechanism of Zn 2+ solvation from strategies including high‐concentration electrolytes, deep eutectic electrolytes, organic molecular electrolytes, and hydrogel electrolytes. Finally, it puts forward insights on the future challenges of AZIBs, so as to promote the development and application of high‐safety energy storage systems.
