1. An apparatus for manufacturing an electrode, the apparatus comprising:
a plurality of guide rollers configured to transport an electrode plate;
a first cutting part configured to:
detect a defect on the electrode plate being transported; and
cut, upon detecting the defect, the electrode plate at a starting part of the defect on the electrode plate to form a defective electrode plate separated from a normal electrode roll;
a first taping part configured to add a first tape to connect the starting part of the defect on the defective electrode plate to a defective electrode roll;
a defective electrode winding part configured to wind the defective electrode roll;
a second cutting part configured to cut the defective electrode plate at an ending part of the defect on the defective electrode plate to form a normal electrode plate separated from the defective electrode plate;
a second taping part configured to add a second tape to connect the normal electrode plate to the normal electrode roll; and
a normal electrode winding part configured to wind the normal electrode roll, and
wherein the first cutting part and the second taping part are formed along a transport direction of the electrode plate, and
wherein the second cutting part and the first taping part are formed under the first cutting part and the second taping part in a direction perpendicular to the transport direction of the electrode plate.
