| titleOfInvention | Method for preparing a separator, separator prepared by the method and electrochemical device comprising the separator |
| abstract | The present invention relates to a method for producing a separator, a separator prepared by the method and an electrochemical device comprising the separator. According to an aspect of the present invention, preparing a mixture by mixing the polymer particles and the pore-forming agent, extruding the mixture through an extruder to form an extruded sheet, stretching the extruded sheet to form a film, solvent Removing the pore former from the elongated membrane, stretching the pore former-removed membrane to 10 to 40% of its initial width (I), and then 7 to 30 of its initial width (I). A method of preparing a separator is provided, the method comprising: relaxing by%, and thermally fixing the stretch-relaxed membrane to form a porous membrane. According to the present invention, it is possible to provide a polyolefin-based separator in which air permeability and strength (transverse direction and penetration) are simultaneously improved without increasing the content of the pore-forming agent for the polymer particles or changing the process conditions of complex extrusion molding during the production of the separator. have. |
