Paper Title:
Low Temperature Electrolyte for Li-Ion Batteries
  Abstract

Electrolyte of LiPF6-ethylene carbonate (EC)-methyl acetate (MA) was prepared. 1 M LiPF6-EC-MA electrolyte presented the conductivity in excess of 1 mS cm-1 at -50 oC. The cyclic voltammetry showed that the electrolyte was better than conventional electrolyte of LiPF6-ethylene carbonate (EC)-diethyl carbonate (DEC) for the formation of SEI film. 1 M LiPF6-EC-MA electrolyte showed much better cycleability than conventional electrolyte of 1 M LiPF6-EC-DE·C for LiCoO2/Li cell. It is a promising alternative electrolyte for Li-ion batteries.
