摘要：
A new-fangled nonaflate anion based ionic liquid ternary gel polymer electrolytes was prepared and their function as an active separator for lithium ion battery applications has been characterized. The ionic liquid gel polymer electrolytes (IGPEs) were prepared using facile solution cast technique by incorporating electrolyte mixtures such as lithium nonafluorobutanesulfonate (LiNfO) and 1-butyl-3-methylimidazolium nonafluorobutanesulfonate (BMImNfO) in poly vinylidenefluoride-co-hexafluoropropylene (PVdF-co-HFP) matrix. The electrochemical performance and the interactions between PVdF-co-HFP, LiNfO and imidazolium-based ionic liquid BMImNfO are comparatively investigated. IGPEs obey Arrhenius relation and its ionic conductivity is found to be maximum of 10(-2) S cm(-1) at 100 degrees C. At low current rate, IGPE also exhibits good cycling performance with LiCoO2 and achieved a maximum discharge capacity of 138.1 mA h g(-1). (C) 2016 Elsevier B.V. All rights reserved.
