The polymer electrolyte of PVC-LENR50-EC-LiClO4 was characterized using impedance spectroscopy (EIS), scanning electron microscopy (SEM) and Fourier transform infrared (ATR-FTIR). From the EIS results shows that electrolyte exhibited the highest ionic conductivity of 2.1 × 10–7 S●cm–1 at the 30 wt.% of LiClO4. The ionic conductivity result was supported by the morphological studies which revealed the good homogeneity of the PVC-LENR50-EC blends as no phase separation was observed. The smooth surface can ease the mobility of ions in the system complexes. In addition, the formation of micro-pores by introducing lithium salts to the electrolyte also improved the transportation properties of L+ ions in the electrolyte system and hence improving its ionic conductivity. The features of complexation of the electrolytes were studied by ATR-FTIR.展开更多
