| Abstract: | A new thin film sodium ion conducting plasticized polymer electrolyte based on poly(vinyl pyrrolidone) (PVP) complexed with
NaClO3 salt systems was prepared by the solution-cast method. The interaction of NaClO3 salt with PVP was confirmed by Infrared (IR) study. Charge transport of these polymer electrolytes is due to ions, which
was confirmed by Wagner’s polarization method. From the conductivity measurements, the highest conductivity value 6.71×10−5 S/cm was observed for the composition PVP:PEG:NaClO3(30:60:10) at room temperature 35 °C. The redox behaviour and good reversibility of the plasiticized electrolytes are confirmed
by electrochemical techniques. Electrochemical cell studies of these polymer electrolytes were analyzed from their discharge
characteristics. The open-circuit voltage (OCV) and short-circuit current (SCC) were found to in the range of 2.52 V to 2.36
V and 760 μA to 1040 μA, respectively. |
