Abstract
Provided are a separator for a lithium secondary battery in which an entire thickness of the separator and a ratio of a heat-resistant layer included in the separator satisfy specific ranges, respectively, and a battery including the same. The separator has significantly excellent heat resistance and mechanical strength, and it is possible to manufacture a high capacity and high output battery using the separator, thereby making it possible to significantly improve safety even in the high capacity and the high output battery.
