This paper describes the synthesis and characterization of a new silver ion conducting solid polymer electrolyte based on activated carbon. Solid nanocomposite polymer electrolytes and their application in energy storage devices has been widely studied because of their environmental safe, no leakage and ion transport mechanism directly connected with the salt (silver iodide) used. Aqueous and non-aqueous electrolytes are widely used in electronic devices but have numerous limitations such as volatility, flammability and leakage. Therefore, we have developed all solid state capacitor in this report and used polymer electrodes and electrolyte as the host. A solid polymer electrode of type 1-x (70 polyethylene oxide: 30 silver iodide): x activated carbon (where x = 10 ≤ x ≤ 50 wt.%) composites have been synthesized using hot press method. The ionic conductivity has been significantly improved for the optimum amount (30 wt.%) of the activated carbon added into the polymer host. The performance of the synthesized electrodes is studied by various physical and electrochemical methods. The leakage current and self-discharge characteristics of the solid state capacitor device have been reported.
