摘要:
A method for manufacturing a polyolefin-based porous separator includes forming a sheet containing a polyolefin-based resin and a diluent, extracting the diluent from the sheet by using an extracting apparatus, and forming a separator by drying the extracted sheet using a drying apparatus provided with an inlet. The shortest distance between an outlet of the extracting apparatus and an inlet of the drying apparatus may be 100 mm or less.
