| abstract |
The present invention is a lithium secondary battery comprising a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode, wherein the separator is a non-crosslinked polyolefin layer; A crosslinked polyolefin layer positioned on one side of the non-crosslinked polyolefin layer and comprising at least one crosslinked bond represented by Formula 1; including, wherein the anode faces the non-crosslinked polyolefin layer of the separation membrane, including the same It relates to a lithium secondary battery and a method of manufacturing the same. The lithium secondary battery according to the present invention has an effect of having a high melt down temperature and high oxidation stability under a high voltage/high temperature environment. |
