Abstract

An ionic liquid gel polymer electrolyte (ILGPE) based on 1-ethyl-3-methyl-imidazolium hexafluorophosphate (EMIPF₆), poly(vinylidenefluoride-hexafluoropropylene) (P(VDF-HFP) and LiPF₆ was prepared by a solution casting method. Its ion transport characteristics and compatibility with LiFePO₄ were investigated by cyclic voltammetry (CV), chronoamperometry, galvanostatic charge-discharge and electrochemical impedance spectroscopy (EIS). The results show that the ionic conductivity and electrochemical window at room temperature are 1.650×10^-3 S cm^-1 and 5.0 V, respectively. The lithiation/delithiation reversibility was improved because of the formation of a passivation layer on the surface of the electrode during the charge-discharge cycles.
