Claim 1:
2. The lithium battery of claim 1, wherein the separator impregnated with the electrolyte has a crystalline index after exposure to heat at 170° C. for 3 hours under an inert atmosphere that is 50% or more of the crystalline index of the separator before the heat exposure, wherein the crystalline index of the separator is expressed as an intensity ratio ((I002−IAM)/I002) of a crystalline peak intensity (I002−IAM) to a total peak intensity I002 of a (002) crystal plane in an X-ray diffraction (XRD) spectrum, and the crystalline peak intensity is a difference between the total peak intensity I002 of the (002) crystal plane and a peak intensity lane of an amorphous phase.
