Method for manufacturing secondary battery electrode, and secondary battery electrode manufactured thereby

A method for manufacturing a plurality of unit electrodes, the method comprising:

• supplying an electrode sheet in a moving direction (MD), wherein the electrode sheet has a plurality of coated portions and a plurality of uncoated portions, wherein the coated portions and the uncoated portions are alternately arranged along the MD, wherein each coated portion has an electrode active material, and each uncoated portion does not have the electrode active material, and wherein the electrode active material is disposed on one or both surfaces of the electrode sheet;
• and
• cutting the uncoated portions to form the plurality of unit electrodes, wherein each unit electrode includes one coated portion,
• wherein the cutting of the uncoated portions comprises:
• pressing a mold or cutter on a first uncoated portion of the plurality of uncoated portions,
• wherein the first uncoated portion separates a first coated portion and a second coated portion of the plurality of coated portions,
• wherein the mold or cutter has a first end and a second end that simultaneously cut the electrode sheet,
• wherein the second end includes a recess portion,
• wherein the first end cuts the electrode sheet such that the remaining electrode sheet under the first coated portion is flush with the first coated portion, and
• wherein the second end simultaneously cuts the electrode sheet such that a portion of the uncoated portion in the shape of the recess portion remains.
