AC conduction mechanism and battery discharge characteristics of (PVC/PEO) polyblend films complexed with potassium chloride

Cole-Cole plots for PVC/PEO: KCl (47.5:47.5:5) polymer blend electrolyte at different temperatures. The complex impedance diagram shows two well-defined regions. The high frequency region semicircle, which is due to bulk effect of the electrolyte, and the linear region at low frequency range, that is attributed to the effect of the blocking electrodes.
