| Zusammenfassung: | The present invention relates to a battery cell for a secondary battery, in which an electrode assembly including a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode is disposed in a battery case, in which the positive electrode has a positive electrode tab extending from a positive electrode current collector formed on one side, and the negative electrode has a negative electrode tab extending from a negative electrode current collector formed on the other side. And the negative electrode has a negative electrode tab extending from a negative electrode current collector formed on one side. The positive tab and the negative tab each have a first bent portion and a second bent portion bent in a v-shape at a tip where the positive tab and the negative tab of the electrode assembly protrude. A sticker-type protective tape is attached to at least one of the first curved portion or the second curved portion and a top end of the electrode |
