  "textContent": "The secondary battery electrode includes a substrate including an uncoated portion including a first surface and a second surface, the second surface being opposite the first surface, and a coated portion on which a first active material layer and a second active material layer are coated, the second active material layer being on a surface of the substrate opposite the first active material layer. The secondary battery also includes an electrode tab coupled to the substrate, a first tape adhered to a portion of the first active material layer around the electrode tab and the uncoated portion, and a second tape opposite the first tape and adhered to a portion of the second active material layer around the uncoated portion. Further, a tensile strength of at least one of the first tape or the second tape is 230 N/mmor greater.",
