POROUS POLYMER ELECTROLYTE AND METHOD FOR PREPARING THE SAME

摘要

PURPOSE: Provided are a porous polymer electrolyte having improved ion conductivity and a method for preparing the same. CONSTITUTION: The high molecular electrolyte is prepared by the steps of (i) mixing polymer compound which is binder into organic solvent to form a binder solution; (ii) forming separation membrane from the binder solution; (iii) drying the separation membrane to evaporate the organic solvent; (iv) mechanically perforating a plurality of fine hole on the dried separation membrane; and (v) immersing the separation membrane into electrolyte solution comprising metal salt dissolved in electrolyte solvent, to form polymer electrolyte.
