摘要

Reliable battery operation in sub-zero environments is critical for polar exploration, military missions, and space applications. However, conventional lithium-ion batteries (LIBs) face inherent limitations at low temperatures by intrinsic hurdle of poor ionic mobility in liquid electrolytes. All-solid-state batteries (ASSBs), which replace liquid electrolytes with non-flammable and non-freezing solid electrolytes, are considered promising alternatives because these solid electrolytes provide high ionic conductivity at low temperatures, superior temperature stability, and exceptional safety. ASSBs still face practical limitations at extremely low temperatures due to degradation caused by interfacial side reactions and mechanical instabilities that increase resistance and polarization. Addressing these challenges is critical to realize the advantages of ASSBs and enable their practical deployment in low-temperature applications. This review provides an overview of historical developments, critical challenges, and recent progress in advancing the low-temperature performance of ASSBs. The key components of ASSBs, including solid electrolytes, cathodes, and anodes, are systematically investigated to develop strategies for improving ASSBs at low temperatures. By highlighting future perspectives, we emphasize both the potential and necessity of ASSBs to overcome the intrinsic limitations of LIBs and ensure reliable energy storage in harsh environments.
