摘　　要：With the increasing demand and striking upsurge in the price of lithium carbonate,sodium-ion batteries(SIBs)have gained significant attentions due to their abundance over lithium-ion batteries(LIBs).Some prototype SIBs have achieved great progress in terms of energy densities.Although SIBs show a relatively higher tolerance at the low temperature than LIBs due to the weaker cation–solvent interaction,the low-temperature performance of SIBs remains a critical challenge restricted by the electrolyte solidification and sluggish interphasial kinetics.In this review,we briefly cover the latest research progress in usable low-temperature electrolytes for SIBs.In the meantime,the mitigating mechanism and low-temperature performance of the electrolytes in different SIB configurations are also discussed.The merits and demerits of ether-based and carbonate-based electrolytes are compared to demonstrate their potential and limitations,thus providing application principles for ether-based and carbonate-based electrolytes at low temperatures to maximize their advantages.Furthermore,mitigation strategies for lowtemperature electrolytes are emphasized to guide the future electrolyte design.Finally,we provide some perspectives on the development of the low-temperature electrolytes for SIBs.
