    A novel MPPBEM based on PVdF-co-HFP–PMMA was prepared with a preferential polymer dissolution process. The N2N_2 gas adsorption/desorption and SEM analysis were used to reveal the porous structure of the polymer matrix and attain the maximum pore size in the range of 251 nm. AC-impedance spectroscopy measurement was carried out to investigate the ionic conductivity of MPPBEMs and achieved a maximum ionic conductivity of 10.23×103Scm110.23 \times 10^{-3} S cm^{-1} at room temperature. The lithium transference numbers of MPPBEMs were measured using the DC-polarization method coupled withAC-impedance spectra are found to be above 0.639. Finally, the electrode/electrolyte interfacial resistance was evaluated by monitoring the impedance response at different time intervals
