Short communication Experimental investigations on PVC--LiAsF_6-DBP polymer electrolyte systems

摘要

Poly(vinyl chloride) (PVC)-LiAsF_6 polymer electrolytes plasticized with dibutyl phthalate in different mole ratios have been studied by means of X-ray diffraction (XRD), infrared spectroscopy (IR) and a.c. impedance spectroscopy. The complexation has been confirmed from XRD and IR studies. A maximum room temperature conductivity (3.938 X l0~-5 S cm~-l ) has been observed for PVC: LiAsF_6: DBP (l0:5:85 mol/100) complex. The log бvs. l/T plots (б= electrical conductivity; T= temperature) show Arrhenius behaviour. The activation energy is estimated and the results are discussed.
