    Abstract: 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.
