英文摘要	LiNi0.5Mn1.5O4 is a promising 5 V class anode material for high power applications; however, before applying in lithium-ion batteries, it is necessary to find more appropriate electrolyte systems to exert the perfect electrochemical performance of LiNi0.5Mn1.5O4. In this paper, the electrochemical performances of lithium difluoro(oxalato)borate (LiODFB)-sulfolane (SL)/dimethyl carbonate (DMC) electrolyte are investigated. It shows high oxidation potentials (>5.4 V) and satisfactory conductivities. When used in LiNi0.5Mn1.5O4/Li cells, compared to the cell with the electrolyte system of LiPF6-ethylene carbonate/DMC, LiODFB-SL/DMC electrolyte exhibits more stable cycle performance and higher discharge voltage plateau (>4.64 V).
