Using the solution-cast approach, new solid polymer electrolyte films containing sodium acetate (CH3COONa) in poly (ethylene glycol) were prepared. These polymer electrolyte systems have been characterized using a variety of experimental approaches, including temperature-dependent conductivity and DSC. The endothermic peak at 59.42°C, which corresponds to the melting temperature of pure PEG, is revealed by DSC measurements.
Due to the addition of salt to the polymer, a minor movement in the melting point, Tm, towards lower temperatures has been detected. At 30°C, the 80PEG+20CH3COONa electrolyte system had a maximum conductivity of 7.9 × 10-6 S/cm. When compared to pure PEG, the conductivity enhanced by two orders of magnitude. The magnitude of conductivity increased as the temperature raised.
