Abstract
An electrode including: a coating part coated with an electrode active material; and an electrode tab part provided on one side of the coating part, wherein the electrode tab part includes: a first electrode tab connected to the one side of the coating part; and a second electrode tab connected to the first electrode tab and bent in a direction of the first electrode tab to overlap one surface of the first electrode tab.
Claims8
An electrode comprising:
- a coating part coated with an electrode active material;
- and
- an electrode tab part provided on one side of the coating part,
- wherein the electrode tab part comprises:
- a first electrode tab connected to the one side of the coating part and extending directly from the coating part in a first direction;
- and
- a second electrode tab connected to the first electrode tab, extending from the first electrode tab in a second direction perpendicular to the first direction and bent in a direction of the first electrode tab to contact and entirely overlap a top surface of the first electrode tab,
- wherein the second electrode tab comprises first and second connection pieces respectively connected to both side surfaces of the first electrode tab, and
- wherein the first and second connection pieces are bent toward the top surface of the first electrode tab to correspondingly overlap the top surface of the first electrode tab.
