英文摘要	Lithium difluoro(oxalate)borate (LiODFB) as an alternative salt for lithium-ion batteries, its application was limited by salt synthesis. In this study, high purity LiODFB was synthesized by simple and continuous technology using purified self-made BF3, the inert atmosphere and vacuum protection was avoided. Moreover, 0.7 mol L-1 LiODFB-PC (propylene carbonate)/EMC (ethyl methyl carbonate)/DMC (dimethyl carbonate) (1:1:1, by volume) were prepared to assembling Li/MCMB (mesocarbon microbead) cell. Solid Electrolyte Interphase (SEI) was formed to stabilized MCMB structure even in one third (by volume) of PC in the electrolyte with the help of LiODFB. LiFePO4/Li cell was assembled as well. The cell based on LiODFB had excellent cycling performance and capacity retention.
