The goal of this research is to create a mixed ion-electron conductor that can be used as an electrode in electrochemical devices. With this in mind, a preparation and characterization of the PVA:PVK:CH3COONH4:EC system has been attempted. During structural investigations, XRD, Optical Microscopy, SEM, and IR tests confirmed the production of a polymer mix and composite electrolyte system. The addition of ammonium acetate improves the electrochemical window, according to electrochemical studies. As evidenced by I-t measurements, ionic charge transport appears to be dominant. At ambient temperature, the ionic conductivity of this system improves by an order of magnitude, with optimum conductivity (1.2710-3 S/cm) for 0.4 mole ammonium acetate concentration. The behaviour of temperature-dependent bulk conductivity is a mix of Arrhenius and VTF. During a.c. conductivity studies, the Jonscher Power law appears to be followed.
