  • Publication number: 20230207959
    Abstract: One aspect of the present invention provides a method of manufacturing a separator including: (a) obtaining a laminate by laminating a first porous support and a second porous support; (b) forming a functional layer by applying a composition including a binder and a solvent on both sides of the laminate and drying the composition; and (c) dividing the laminate into two separators along an interface formed by the lamination, and a separator manufactured using the method.
