Abstract

In order to avoid the difficulties and high costs associated with salt synthesis as well as to improve the reliable performances of lithium-ion batteries (LIBs), lithium difluoro(sulfato)borate (LiBF2SO4) was investigated as a novel functional additive salt for lithium hexafluorophosphate (LiPF6)-ethylene carbonate/dimethyl carbonate electrolyte. It was found that the addition of 5 wt% LiBF2SO4 to the LiPF6-basedelectrolyte can significantly decrease the interfacial impedance of cells. Moreover, LiBF2SO4 additive could obviously improve both of the capacity retention and the rate performance of lithium-ion cells. Therefore, LiBF2SO4 is a promising additive for high-performance LIBs for power applications, such as hybrid electrical vehicles.
