Separator for lithium secondary battery and lithium secondary battery comprising the same |
摘要 |
Disclosed is a separator for a lithium secondary battery and a lithium secondary battery comprising the same. The separator may include a thermoplastic polyolefin-based polymer porous sheet and an aramid-based non-woven fabric sheet stacked on at least one surface of the polyolefin-based polymer porous sheet, wherein the polyolefin-based polymer sheet and the aramid-based non-woven fabric sheet are adhered with an adhesive, and the adhesive loses an adhesive performance at 80° C. or more to separate the two sheets. The separator has a shut-down function and excellent high-temperature shape stability. |
