Electrolytes for Aqueous Zn-Ion Batteries Working in Wide-Temperature Range: Progress and Perspective

Abstract

Aqueous Zn-ion Batteries (AZIBs) have garnered significant interest in recent years, owing to their inherent safety, affordability, and eco-friendliness. Recently, substantial research has been conducted to broaden the application scenarios of AZIBs by regulating the electrode and electrolyte materials. In this review, we provide a comprehensive analysis of the challenges and solutions associated with AZIBs to meet extreme conditions, such as low temperatures, high temperatures, and wide temperature ranges. We also discuss electrolyte optimization strategies for each of these conditions. Finally, we outline potential avenues for further advancements and offer insights into the future of this burgeoning field of AZIBs.
