Abstract

The low temperature performance of electrolytes containing FEC including FEC+EMC,EC and PC,as well as the compatibility of electrolytes with LiFePO4 anode and with MCMB cathode were investigated.The electrolyte exhibits a high value of ionic conductivity at low temperature.The stability of cathode was enhanced by the formation of SEI film at 1.6 V as a result of FEC reaction.The infrared spectra showed that FEC can suppress decomposition of other solvents during SEI formation,and lower the resistance of SEI on MCMB cathode.The electrochemistry test indicates that Li-ion batteries with FEC electrolyte display high capacity at low temperature and better rate performance.
