From Fundamentals to Practice: Electrolyte Strategies for Zinc‐Ion Batteries in Extreme Temperature

Abstract

In the pursuit of advanced energy storage technologies that promote sustainable energy solutions, zinc‐ion batteries (ZIBs) have emerged as a promising alternative to lithium‐ion batteries due to their abundance, safety, and environmental advantages. However, the failure mechanisms of ZIBs under extreme temperatures are still not fully understood, presenting significant challenges to their development and commercialization. Therefore, innovative strategies are essential to enhance their adaptability to temperature extremes. In this review, we first explore the thermodynamic and kinetic aspects of performance degradation under extreme temperatures, focusing on key factors such as ion diffusion and redox processes at electrode interfaces. We then comprehensively summarize and discuss the existing approaches for various electrolyte types, including aqueous, nonaqueous, and solid state. Finally, we highlight the key challenges and future prospects for ZIBs operating under extreme temperature conditions. The insights presented in this review are expected to accelerate the advancement of ZIBs and facilitate their practical implementation in large‐scale energy storage systems.
