Rechargeable battery and manufacturing method thereof
A rechargeable battery and a manufacturing method of the same are provided, which can aid in preventing an electric short from occurring between electrode plates by forming a cutting portion of each on the electrode plates in the shape of a curved surface or a bead having a uniform thickness and/or a diameter sufficient to prevent or substantially prevent the cutting portion from piercing a separator separating the electrode plates from each other. In a present embodiment, the electrode assembly includes an electrode plate having a current collector plate, a coating portion having an electrically active material coated on the current collector plate, a non-coating portion formed at an edge of the current collector plate and not coated with the electrically active material, a cutting portion inwardly formed from the non-coating portion, and a curved portion formed along the cutting portion in a thickness direction of the non-coating portion.
