ABSTRACT. Polymer electrolytes PVC – LiNO3 – CdO were prepared using solution casting technique and were characterized by AC impedance, SEM & TGA/DTA techniques. Ionic conductivity of the polymer electrolytes was determined using AC impedance method. Maximum value of ionic conductivity was observed for the optimized composition of PVC and LiNO3 in the polymer electrolyte. SEM micrographs brought out a good correlation among the surface morphology, ionic conductivity and amorphous/crystalline structures of the studied polymer electrolytes.

The thermal properties of polyvinyl chloride (PVC) – Lithium Nitrate (LiNO3)- Cadmium Oxide(CdO) by Thermo Gravimetric Analysis(TGA) gives rise the information on the thermal stability of polymer electrolytes.
