Ionic liquid gel polymer electrolytes (ILPEs) based on electrospun P(VdF-HFP) membrane were prepared by incorporating RTILs, BMImTESI or BMImBF(4). A suitable BMIm cation based ionic liquid with lithium salt and influence of temperature on electrochemical performance was investigated. The BMImTFSI-based polymer electrolyte with LiTFSI salt showed better electrochemical properties and the properties increase with increasing the operation temperature to 40 degrees C, to 140 mAh g(-1) discharge capacity at 1 C-rate. However, after 40 degrees C the properties remained the same even when the temperature was increased at high current density. (C) 2013 Elsevier Ltd. All rights reserved.
