<p>This paper reports electrochemical studies on Silver ion (Ag⁺) conducting plasticized nanocomposite polymer blend electrolyte and its usage in a prototype silver polymer battery with Ag₂O cathode and Ag anode. The [(PVA)₄₀:(PEO)₄₀:(AgNO₃)₅:(PEG)₉:(Al₂O₃)₆]₁₀₀ plasticized nanocomposite polymer blend electrolyte is synthesized by a simple solution cast technique and is chosen as an ‘electrolyte’ in the lab-scale manufacturing of Ag/Ag₂O cell. The dc conductivity of this electrolyte specimen gradually increases with increasing temperature as per ‘Vogel-Tamman-Fulcher (VTF) behavior’. The ac conductivity spectra and scaling of this electrolyte specimens at different temperatures is discussed. Electrochemical performance of Ag polymer battery is examined in terms of discharge characteristics and cell parameters for various appropriate external loads ranging from 330 Ω to 4.7 kΩ. The experimental investigations demonstrate the feasibility of designing a prototype primary Silver polymer battery with Ag₂O cathode and Ag anode for low current applications.</p>
