Zinc‐based energy storage devices have received extensive attention because of their low‐cost and high‐safety characteristics. Numerous breakthroughs have been made in this field in recent years. Some special applications, such as polar inspections, oil exploration, high‐altitude drones, aerospace, and cold regions, place higher requirements on the performance of zinc‐based energy storage devices under extreme conditions of low temperatures. However, aqueous electrolytes will freeze at sub‐zero temperatures, resulting in device failure. Besides, the sluggish kinetics of the electrodes at low temperatures limits their capacity retention and rate performance. During the past several years, considerable efforts have been devoted to circumventing these problems. In this review, we summarize the recent progress on zinc metal energy storage devices under extreme conditions of low temperatures. Three aspects including the design of anti‐freezing electrolytes, low‐temperature‐resistant cathode materials, and zinc anodes are discussed. Finally, a perspective on this field is summarized to guide future researches.

极端低温条件下的锌金属储能装置

锌基储能设备因其低成本和高安全性而受到广泛关注。近年来，该领域取得了许多突破。极地检查，石油勘探，高空无人机，航空航天和寒冷地区等一些特殊应用对锌基储能设备在极端低温条件下的性能提出了更高的要求。但是，水性电解质会在低于零的温度下冻结，从而导致设备故障。此外，电极在低温下的缓慢动力学限制了它们的容量保持率和速率性能。在过去的几年中，为解决这些问题做出了巨大的努力。在这篇评论中，我们总结了在极端低温条件下锌金属储能设备的最新进展。讨论了防冻电解液的设计，耐低温阴极材料和锌阳极三个方面。最后，总结了该领域的观点以指导未来的研究。
