This paper presents the application of Solid Polymer Membrane toward the electrolyte purpose of electrochemical device fabrication to avoid the electrolyte leakage. PVDF-HFP and PEMA polymers are hosting to membrane formation and ethylene carbonate to give the support as flexible nature of membrane. PVDF HFP/PEMA/EC/Acetone based Complexes Polymer Solution (CPS) and PVDF-HFP/PEMA/EC based Solid Polymer Membrane (SPM). The resultant CPS and SPM are subjected to Electrochemical Impedance Spectroscopy and also analysed the electrochemical properties such as Resistance (R), Capacitance (C), Solution Resistance (Rs), Double Layer Capacitance (Cdl) and Charge Transfer Resistance (Rct). After the conversion of CPS to SPM solution resistance is reduced which is confirm the acetone completely removed from the solid polymer membrane. The charge transfer resistance also reduced from the order of 105 to 104 leads the electronic conduction when these type of SPM using the electrolyte preparation for electrochemical application
