SEPARATOR FOR ELECTROCHEMICAL DEVICE AND METHOD FOR MANUFACTURING THE SAME

A separator for an electrochemical device, including a porous polymer substrate and an inorganic coating layer formed on at least one surface of the porous polymer substrate. The inorganic coating layer includes inorganic particles and a binder resin. The binder resin includes a polyvinylidene fluoride (PVdF)-based polymer having a main chain, and at least one hydrogen atom in the main chain of the PVdF-based polymer is substituted with an acrylic compound-derived functional group.
