Aqueous rechargeable metal-ion batteries (ARMBs) represent one of the current research frontiers due to their low cost, high safety, and other unique features. Evolving to a practically useful device, the ARMBs must be adaptable to various ambient, especially the cold weather. While much effort has been made on organic electrolyte batteries operating at low temperatures, the study on low-temperature ARMBs is still in its infancy. The challenge mainly comes from water freezing at subzero temperatures, resulting in dramatically retarded kinetics. Here, the freezing behavior of water and its effects on subzero performances of ARMBs are first discussed. Then all strategies used to enhance subzero temperature performances of ARMBs by associating them with battery kinetics are summarized. The subzero temperature performances of ARMBs and organic electrolyte batteries are compared. The final section presents potential directions for further improvements and future perspectives of this thriving field.
水系可充电金属离子电池（ARMBs）因其低成本、高安全性和其他独特特性而成为当前的研究前沿领域之一。要发展成为实用的设备，ARMBs必须适应各种环境，尤其是寒冷天气。虽然在低温下工作的有机电解质电池方面已经做了很多努力，但低温ARMBs的研究仍处于起步阶段。挑战主要来自零下温度下水的冻结，导致动力学显著迟缓。在此，首先讨论水的冻结行为及其对ARMBs低温性能的影响。然后总结了通过将ARMBs与电池动力学相关联来提高其低温性能的所有策略。比较了ARMBs和有机电解质电池的低温性能。最后一部分提出了该蓬勃发展领域进一步改进的潜在方向和未来展望。
