    Abstract:

    Microporous films composed of PVDF-HFP were prepared by the phase inverse process. Electric properties of these microporous film and Celgard®2300 using as membrane for Li-ion batteries have been measured and compared. PVDF-HFP based membrane adsorbed electrolyte has ionic conductivity above 10−3 s/cm at 25 °C, while the Celgard®2300 in the same case has ionic conductivity was 6.7*10−4s/cm at room temperature. It is stable up to in electrolyte and has good interfacial character and long term stafibilyty for lithium electrode.
