چکیده انگلیسی
Plasticised polymer blend electrolytes based on poly(vinylidenefluoride-co-hexafluoropropylene) (PVdF-co-HFP) and poly(ethyl methacrylate) (PEMA) were prepared for different lithium salts LiX (XÂ =Â ClO4, CF3SO3, BF4 and N[CF3SO2]2) using facile solution casting. To confirm the structures and complexations of the electrolyte films, the prepared electrolytes were subjected to XRD and FTIR analysis. TG-DTA was used to ascertain the thermal stability of the electrolytes, and the porous nature of the electrolytes was identified using scanning electron microscopy via ion-hopping conduction. AC impedance analysis was performed for all the electrolyte samples at various temperatures from 303 to 363Â K. The results suggest that among the various lithium salts, LiN[CF3SO2]2-based electrolytes exhibited the highest ionic conductivity (0.918Â ÃÂ 10â3Â SÂ cmâ1). The temperature dependence of the ionic conductivity also complies with the VTF relation.
