  • Publication number: 20250149739
    Abstract: Disclosed is a separator for an electrochemical device that includes a polymer substrate with small and uniform pores and an aqueous organic/inorganic composite porous coating layer and an adhesive coating layer and which is improved in compression resistance, and a method of making the separator and the electrochemical device including the separator. The separator with improved compression resistance is not easily deformed by well resisting pressure applied thereto during a lamination process in which an electrode and the separator are applied with heat and pressure so as to be bonded to each other. In addition, when pressure is applied, the coating layer serves as a buffer, thereby reducing the pressing force exerted on the porous substrate. Thus, deformation of the separator is inhibited.
