摘要：

In this paper, the electrochemical performance of a new low-temperature electrolyte, 0.9 mol L-1 lithium oxalyldifluoroborate (LiODFB)/LiBF4 (5.365:1, by mass) mixed salts in the ethylene carbonate (EC)/dimethyl sulfite (DMS)/ethyl methyl carbonate (EMC) mixed solvent (1:1:3, by volume, the same below), is studied to seek the promising candidate for advanced low-temperature lithium-ion batteries (LIBs). The results show that LIBs using this new electrolyte can be operable well at temperature below -20 A degrees C. This is useful to expand the application range of LIBs, especially at specific low-temperature environments, such as military and aerospace applications.
