英文摘要	LiNi0.5Mn1.5O4 material is a promising 5 V class cathode 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 LiNi 0.5Mn1.5O4 material. In this paper, the electrochemical performances of LiBOB-propylene carbonate (PC)/dimethyl carbonate (DMC) electrolyte are investigated. It shows high oxidation potentials (>5.5 V) and satisfactory conductivities, When used in LiNi 0.5Mn1.5O4/Li cells, compared to the cell with the electrolyte system of LiPF6-ethylene carbonate (EC)/dimethyl carbonate (DMC) electrolyte, LiBOB-PC/DMC electrolyte exhibit several advantages, such as more stable cycle performance, higher discharge voltage plateau (>4.64 V), higher coulomb efficiency, and higher mean voltage (4.55 V). © (2012) Trans Tech Publications, Switzerland.
