  • Publication number: 20230077425
    Abstract: A separator for an electrochemical device including a porous separator substrate including a polymer material, and a porous coating layer coated on at least one surface of the porous separator substrate. The porous coating layer includes inorganic particles and a binder resin. The binder resin includes a mixture of polyvinyl acetate (PVAc) with an acrylic binder resin. The separator has improved wettability with an electrolyte by virtue of relatively high polarity of PVAc. In addition, it is possible to improve the peel force between the separator substrate and the porous coating layer by introducing PVAc and to reduce the thickness of the porous coating layer. Therefore, when introducing the separator to a battery, it is possible to improve the resistance characteristics, and to inhibit the porous coating layer from being spaced apart from the separator substrate or to inhibit the inorganic particles from being detached from the porous coating layer.

  • Publication number: 20220285722
    Abstract: Disclosed is an electrode assembly manufacturing method, in which, in a step of stacking and pressing electrodes and a separator, the pressing is performed in that state in which pores of a porous substrate are filled with a polymer solution. The form or volume of the pores is not changed due to the polymer solution. Consequently, porosity of the separator after manufacture of an electrode assembly is similar to porosity of the separator before stacking. As a result, a battery including the electrode assembly has high ionic conductivity and excellent performance.
