Abstract
En 中文
In this work, nine composite polymer electrolytes (CPE) based on polyvinylidene fluoride (PVdF) with different fillers PVdF-PEG (PVP)-X (where X = Li2SO4, NaCl, LiCl, LiF) were synthesized at the room temperature. The composition of composite polymer electrolytes providing the highest ionic conductivity was determined. The effect of the polyvinylpyrrolidone (PVP) on the ionic conductivity of the film was established. The ionic conductivities of the obtained polymer electrolytes were calculated. Solid polymer electrolyte with the composition PVDF + NMP + LiCl shows the highest ionic conductivity which is equal to 6.07.10(-1) Ohm(-1).cm(-1). (C) 2020 Elsevier Ltd. All rights reserved.
