preparation of porous polymer film hybrid-type polymer electrolytes and lithium secondary polymer batteries using the polymer film and the preparation thereof

摘要

The present invention relates to a novel method for preparing a porous polymer membrane for a hybrid polymer electrolyte, a polymer electrolyte and a lithium polymer secondary battery using the same, and a method for manufacturing the same, and a polymer material and a solvent component and a non-solvent component for the polymer material. The porous polymer membrane of the present invention, which is prepared by a method of casting a polymer mixed solution comprising a substrate on a substrate and then removing the solvent component by evaporation and then removing the nonsolvent component, has a high porosity and has a large amount of liquid electrolyte. It can contain a polymer electrolyte having a high ion conductivity can be provided, the lithium polymer secondary battery comprising the same has a low interfacial resistance and excellent charge and discharge characteristics.
