Silver Ion Conducting Characteristics Of A Polyethylene Oxide-based Composite Polymer Electrolyte And Application In Solid State Batteries

The matrix embracing a combination of polyethylene oxide [PEO] as the host polymer component and silver trifluoromethane sulfonate [AgCF3SO3] (also known as silver triflate) as the dopant salt yielding a composite polymer electrolyte [CPE] with varying compositions based on rich contents of Oxygen/Metal [O/M] ratio has been prepared in the form of thin film specimens using solution casting technique and examined for its application in a solid state battery configuration as a test cell. Such composite polymeric films optimized using electrical conductivity studies have provided realization of a maximum electrical conductivity value of 2.9 ×10 -5 Scm -1 at room temperature (298 K) whereas their temperature-dependent electrical conductivity is found to obey the Arrhenius behavior. Silver ionic transference number (tAg + ) data for these polymeric composites were indomitable using ac/dc polarization technique whereas the occurrence of a transition of phase in accordance with structural and
