Beschreibung
Zusammenfassung:	A heat resistant porous layer composition for a separator for an electrochemical battery includes a compound represented by Formula 1, a polyvinylidene fluoride (PVdF)-based polymer, the PVdF-based polymer including one or more of a PVdF-based homopolymer or a PVdF-hexafluoropropylene-based copolymer in which a unit originating from hexafluoropropylene is present in an amount of 15 wt % or less based on the total weight of the PVdF-hexafluoropropylene-based copolymer, the PVdF-hexafluoropropylene-based copolymer having a weight average molecular weight of 600,000 g/mol or more, an initiator; and a solvent, wherein Formula 1 is defined herein.
