Description
Summary:Aqueous rechargeable energy storage (ARES) has received tremendous attention in recent years due to its intrinsic merits of low cost, high safety, and environmental friendliness. However, the relatively higher freezing point of conventional aqueous electrolytes results in sluggish kinetics and inferior ion transport efficiency under low temperature, severely restricting their further development and practical applications. In order to deal with the existing issues, the design principles to develop low‐temperature ARES with excellent performance are discussed in‐depth and precisely classified, primarily with respect to electrode modification and electrolyte regulation. In addition, the related studies about low‐temperature ARES are systematically and comprehensively summarized. Finally, the critical bottlenecks, some suggestions, and future perspectives are also provided, which will help to address the current challenges of low‐temperature ARES. This review is expected to deepen the fundamental understanding of low‐temperature ARES and offer guiding suggestions to boost their future applications. The studies on low‐temperature aqueous rechargeable energy storage (ARES) are systematically and comprehensively summarized. Electrolyte optimization and electrode modification are the main design strategies to efficiently improve their low‐temperature electrochemical performance. The critical bottlenecks and future perspectives of low‐temperature ARES are also provided, aiming to deepen the fundamental understanding of low‐temperature ARES and offer guiding suggestions to boost their future applications.
