Paper Details

In recent years, large scientific and technical interest in lithium polymer secondary batteries leads to thedevelopment of electrolytes with high electrochemical windows. Several researches deliberate the performance ofpolymer electrolytes owing to its high energy density, ease of preparation, compatibility between the electrodes etc.Numerous strategies are followed to match the ionic conductivity and mechanical stability of polymer electrolytes. Thiswork describes the clear effect of plasticizer on the performance of lithium ion batteries with four different plasticizersuch as ethylene carbonate (EC), propylene carbonate (PC), γ-Butyrolactone (γBL ) and diethyl carbonate (DEC) wereused. Gel polymer electrolytes comprising of PVdC- AN (52wt%) – LiClO4 (8wt.%)–ZrO2 (6wt%)- X(40) (X- EC,PC,γBL, DEC) were prepared by solution casting technique. The structural and complexation formation of the preparedelectrolytes have been confirmed by XRD and FTIR analysis. The effect of plasticizer on ionic conductivity is depictedusing a.c impedance studies in the temperature range 303 -363 K. The highest ionic conductivity value 1.2×10-3 S/ cmwas measured for the sample incorporating EC, owing to its high dielectric constant (89.6). Thermal stability of thesamples has been examined using TG/DTA. The maximum conducting sample, with plasticizer EC can be operated upto 160 C. The morphology is analyzed by SEM.
