POROUS POLYOLEFIN SEPARATOR AND METHOD FOR MANUFACTURING THE SAME |
| 摘要 |
A method for manufacturing a polyolefin separator, including forming a sheet including a polyolefin resin and a plasticizer; stretching the sheet E1 times in a longitudinal direction at a temperature of T1, followed by stretching the sheet E2 times in a transverse direction at a temperature of T2, wherein T1<115° C., T2<115° C., and T2≧T1, and E1×E2=55 to 80, E1≧7, and E2≧7; and extracting the plasticizer from the stretched sheet. |
