Study of the Thermal Stability and Ionic Conductivity of Polystyrene-Co-Acrylonitrile Based Composite Solid Polymer Electrolytes Incorporated with different Lithium Salts
In the present study, a series of poly(styrene-co-acrylonitrile) (SAN) polymer electrolytes and SAN- poly(vinyl alcohol) (PVA) polymer blend electrolytes were prepared with different lithium salts using a solvent casting technique. TG & DSC studies were carried out to investigate the thermal stability of the polymer blend electrolytes. Ionic conductivities of these electrolytes were measured by AC impedance spectroscopy. Results for conductivity studies have shown that the polymer with SAN/PVA complex with 5 % LiBr exhibits the highest conductivity of 8.7 × 10−5 S/cm at 70°C. The temperature dependence of the polymer electrolyte films obeys Arrhenius relation.
