Olivine-type LiFePO4 and crystal structure LiMn2O4 or LiNi0.5Mn1.5O4 are promising cathode materials for electric vehicles (EVs) applications. To find more appropriate electrolyte systems to exert the perfect electrochemical performance of LiFePO4, LiMn2O4 and LiNi0.5Mn1.5O4 cathodes, the electrochemical performances of LiBOB-ethylene carbonate (EC)/ethyl methyl carbonate (EMC)/diethyl carbonate (DEC) electrolyte are investigated in this paper. In LiFePO4/Li, LiMn2O4/Li and LiNi0.5Mn1.5O4/Li cells, this novel electrolyte exhibits several advantages, such as stable cycle performance and good rate performance. It suggests that LiBOB-EC/EMC/DEC electrolyte has good compatibility with the three kinds of cathodes, and would be an attractive electrolyte for lithium-ion batteries based upon LiFePO4, LiMn2O4 and LiNi0.5Mn1.5O4 cathodes.

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-1LiODFB-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.
