    摘要： The present disclosure relates to a separator including: a non-crosslinked polyolefin layer; and a crosslinked polyolefin layer disposed on one surface of the non-crosslinked polyolefin layer and having at least one crosslinking bond represented by the following Chemical Formula 1, wherein the positive electrode faces the non-crosslinked polyolefin layer of the separator. The present disclosure also relates to a lithium secondary battery including a positive electrode, a negative electrode and the separator interposed between the positive electrode and the negative electrode, as well as a method for manufacturing the same. The lithium secondary battery has a high melt-down temperature and shows high oxidation stability under high-voltage/high-temperature environment.

    摘要： The present invention provides a method for manufacturing a separator, comprising the steps of (S1) preparing a porous planar substrate having multiple pores; (S2) coating a coating solution obtained by dissolving a binder polymer in a solvent and dispersing inoganic particles therein on the porous substrate to form a porous coating layer and drying the porous coating layer; and (S3) applying a binder solution on the surface of the dried porous coating layer to form an adhesive layer, wherein the binder solution has a surface energy of at least 10 mN/m higher than that of the porous coating layer and a contact angle of the binder solution to the surface of the porous coating layer maintained at 80° or more for 30 seconds. In accordance with the present invention, a separator capable of obtaining sufficient adhesion force with minimizing the amount of an adhesive used for the adhesion with an electrode, and minimizing the deterioration of battery performances can be easily manufactured.

    摘要： Disclosed is a method of manufacturing an electrode-separator composite: including (S1) coating an electrode active material slurry on at least one surface of an electrode current collector and drying to form an electrode, (S2) coating a polymer solution containing polymer particles on at least one surface of the electrode to form a separator coating layer, and (S3) drying the separator coating layer to form a porous separator, and an electrode-separator composite manufactured by the manufacturing method and a lithium secondary battery comprising the same.
    According to the present disclosure, a porous separator is manufactured by coating polymer particles on an electrode, thereby effectively controlling the uniformity and tortuosity of the pores, a porous separator is manufactured by directly coating a polymer solution on an electrode without separately manufacturing a separator, thereby saving the process costs and time, and further, when a functional group able to capture manganese is attached to the surface of polymer particles constituting a separator, deterioration in battery performance may be prevented through removal of manganese ions that may be deposited on an anode during operation of a battery.
