Abstract：Sodium-ion batteries(SIBs)are regarded as a promising choice for the large-scale energy storage applications due to their ample source,low cost,and high safety.However,the practical use of SIBs are limited,especially in some high-altitude and large temperature differences regions.In low-temperature(LT)environments,the electrochemical performance and safety are compromised owing to the diffusion and migration rates of sodium ions in SIBs significantly decrease.Therefore,enhancing the LT performance of SIBs is crucial,with the rational design and modification of anodes materials being particularly critical.This paper review recent research progress of anode materials in LT environments,analyzed the difficulties and challenges faced by anode materials at LT,and three modification methods are overviewed.By means of various strategies such as structural optimization,surface/interfacial modification and conductive network engineering,electrochemical performance of anode materials can be effectively enhanced at LT.Significant improvements are manifested in enhanced ionic diffusion kinetics,stabilized electrode-electrolyte interface and reinforced structural integrity.Finally,future research directions for future LT SIBs are proposed,which provides references for promoting the application of SIBs.
