  • SEPARATOR AND METHOD FOR MANUFACTURING SAME
    Publication number: 20240304950
    Abstract: The present disclosure relates to a separator and a method of manufacturing the separator. The separator includes a porous support and a hydrophilic polymer applied to the surface of the porous support through a solution including the hydrophilic polymer and a solvent, and satisfies the following Equation: 0.015?(C*D)/(A*B)?0.65, where A is a thickness (?m) of the porous support, B is an air permeability (Gurley, seconds/100 ml) of the porous support, C is a porosity (% by volume) of the porous support, and D is a content (% by weight) of the hydrophilic polymer in the solution.
