Abstract
An electrode for a secondary battery and a method for manufacturing the electrode are disclosed. According to an embodiment, a first cutting line and a second cutting line, along which an electrode sheet is cut, may cross each other to form a crossing area on the electrode sheet, and in the crossing area, the first cutting line may be formed as a straight line, and one end of the straight line may be connected to a curved line constituting a portion of the first cutting line, wherein the straight line may be connected to the curved line by a tangent line.
Claims9
A method for manufacturing an electrode, the method comprising:
- a first cutting step of cutting a portion of an electrode sheet along a first cutting line (N1) comprising a closed curve to form a first electrode having a shape corresponding to the closed curve of the first cutting line (N1);
- and
- a second cutting step of additionally cutting a portion of the electrode sheet along a second cutting line (N2) comprising a closed curve to form a second electrode having a shape corresponding to the closed curve of the second cutting line (N2), which is separated from the first electrode formed in the first cutting step, after the first cutting step,
- wherein the first cutting line (N1) and the second cutting line (N2) cross each other to form a crossing area (C1) on the electrode sheet,
- wherein, in the crossing area (C1), the first cutting line (N1) is formed as a first straight line (SL1), and a first end of the first straight line (SL1) is connected to a curved line (CL) constituting a portion of the first cutting line (N1), and
- wherein the first straight line (SL1) is connected to the curved line (CL) by a tangent line.
