    摘要： A separator for an electrochemical device provided with a porous coating layer including multiple types of binder resins, and a method for manufacturing the same. The separator shows high adhesion between an electrode and the separator, even when any separate adhesive layer is not disposed on the surface of the separator. In addition, the separator shows higher adhesion to an electrode, as compared to a separator using a fluorinated binder resin, such as polyvinylidene fluoride, used conventionally in the art. Therefore, when introducing the separator to a battery, it is possible to manufacture an electrode assembly under a mild temperature and pressure condition, to improve the productivity of assemblage, to reduce defect generation, and thus to increase the yield. Further, the separator shows high affinity to an electrolyte, as compared to a semi-crystalline polymer, such as a fluorinated binder resin, and thus improves the output characteristics of a battery.

    摘要： A method and apparatus for manufacturing a separator, and a separator obtained thereby. The method for manufacturing a separator includes applying a solvent for pore impregnation onto a first surface of a porous polymer substrate, before applying slurry for forming a first porous coating layer and a second porous coating layer. In this manner, it is possible to provide a separator which has a small deviation in physical properties between the porous coating layers on the first surface and the second surface of the porous polymer substrate.
    The present disclosure relates to a method and apparatus for manufacturing a separator, and a separator obtained thereby. The method for manufacturing a separator according to an embodiment of the present disclosure includes applying a solvent for pore impregnation onto a porous polymer substrate, before applying slurry for forming a porous coating layer thereto. In this manner, it is possible to provide a separator which shows a small deviation in physical properties between the porous coating layers formed on the top surface and the back surface of the porous polymer substrate.

    摘要： A method for manufacturing unit cells includes preparing a pre-cell having a first separator sheet and a plurality of first electrodes disposed on the first separator sheet while being spaced apart from one another; forming a cutting guide line having a plurality of though-holes spaced apart from one another on the pre-cell; and cutting the pre-cell along the cutting guide line to form a plurality of unit cells. An apparatus for manufacturing unit cells includes a hole-forming unit configured to form a cutting guide line on a pre-cell having a separator sheet and electrodes disposed on the separator sheet where the cutting guide line has a plurality of though-holes spaced apart from one another; and a cutting unit configured to cut the pre-cell along the cutting guide line to form a plurality of unit cells.
