Abstract
An apparatus for coating electrode active material slurry includes: a transfer unit continuously transferring an electrode current collector in a predetermined process direction; and a coating die which is reciprocally movable in the process direction or an opposite direction to the process direction and coats the active material slurry on a predetermined coating area of the electrode current collector transferred by the transfer unit, wherein the coating die stands by at a predetermined coating start position and, when a balcony region corresponding to a leading end of the coating area reaches the coating start position, coats the active material slurry on the balcony region while moving from the coating start position to a main coating position that is spaced apart from the coating start position by a predetermined distance in the opposite direction.
