英文摘要	研究含FEC溶剂电解液(FEC+EMC,EC,PC)的低温性能及其与磷酸铁锂正极或中间相碳微球(MCMB)负极的匹配.该电解液具有较高的低温电导率,FEC可在1.6 V与负极反应成膜,有效地提高负极稳定性.红外测试发现,FEC可抑制其它电解液溶剂在负极成膜过程中的分解,在常温(20℃)和低温(-20℃)下形成的SEI膜阻抗均较低.电化学测试表明,以该电解液装配的锂离子电池(电极)具有较高的低温放电容量和倍率性能.; 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.; 作者联系地址：动力电池及化学能源材料北京市高等学校工程研究中心北京理工大学化工与环境学院;国家高技术绿色材料发展中心;; Author's Address: 1.Beijing Higher Institution Engineering Research Center of Power Battery and Chemical Energy Materials School of Chemical Engineering and Environment Science,Beijing Institute of Technology, Beijing 100081,China;2.National Development Center of High Technology Green Materials,Beijing 100081,China
