¨【Name】LiDFOB;LiFBOB;Lithium difluoro(oxalato)borate;Lithium difluoro(oxalato)borate(1- );LithiuM Oxalyldifluoroborate;LithiuM difluoro oxalate borate;LIF2OB;LIFOB
¨【CAS Registry number】:409071-16-5
¨【Molecular Formula】:  LiODFB
¨Uses:(1) LiODFB has higher thermal stability and much less free acid content, and released CO2  possibly provides good safety of cells.(2) The cells using LiODFB-based electrolyte have lower capacity fade than the cells using LiPF6-based electrolyte after 100 cycles at 55 ℃, and higher initial capacity retention at the elevated temperature.(3) At 0.5C and 1C discharge rates, the rate capability of the cells with the LiODFB-based electrolyte is almost the same as that of the cells with the LiPF6-based electrolyte after 20 cycles,and the gap between the two cells is tiny.(4) Interface properties of the cells show that LiODFB is reduced and forms a thickening and protective SEI film on the negative electrode. Although this can increase the impedance of SEI film, the cells still can provide a preferable rate performance. More work is needed to carry out in the lithium battery of commercialization in the future.
