Abstract
Polyethylene oxide PEOpolyvinylpyrrolidone PVP blended Na+ ion conducting solid polymeric membranes 1−x 75PEO25NaPO3 + x PVP where 0 x 12 wt are reported The polymeric blending was done using a solventfree hotpress method Two orders of conductivity enhancement σ ca 107 × 10−5 S·cm−1 have been achieved with 3 wt of PVP ie the composition 9775PEO25NaPO3 + 3PVP from that of the pure host 75PEO25NaPO3 The conductivity enhancement in PEOPVP blended solid polymeric membranes have been explained by the ionic conductivity ionic mobility and mobile ion concentration measurements Materials characterization and polymersalt complexation were done with the help of Xray diffraction XRD scanning electron microscopy SEM differential scanning calorimetry DSC and thermo gravimetric analysis TGA studies The temperature dependent conductivity studies have also been done to compute the activation energy E a values from lg σ1/T Arrhenius plots A solid state polymeric battery was fabricated by using optimum conducting composition of solid polymer electrolyte SPE OCC and some important cell parameters were also calculated from the discharge profile of the cell
