Abstract
Official abstract text for this publication.
A rechargeable battery according to an exemplary embodiment of the present invention includes: an electrode assembly which is wound and includes a first electrode, a second electrode, and a separator interposed between the first electrode and the second electrode; a casing which accommodates the electrode assembly; a first electrode tab which is connected to a non-coated portion of the first electrode; a second electrode tab which is connected to a non-coated portion of the second electrode; and a first insulating tape which is positioned at a winding start portion of the electrode assembly and attached to the non-coated portion of the first electrode so as to at least cover a center of a first curved portion which is curvedly formed as the electrode assembly is wound.

1 . A rechargeable battery comprising: an electrode assembly which is wound and includes a first electrode, a second electrode, and a separator interposed between the first electrode and the second electrode; a casing which accommodates the electrode assembly; a first electrode tab which is connected to a non-coated portion of the first electrode; a second electrode tab which is connected to a non-coated portion of the second electrode; and a first insulating tape which is positioned at a winding start portion of the electrode assembly and attached to the non-coated portion of the first electrode so as to at least cover a center of a first curved portion which is curvedly formed as the electrode assembly is wound. 2 . The rechargeable battery of claim 1 , wherein: the first insulating tape is attached to a coated portion of the first electrode which is coated with an active material. 3 . The rechargeable battery of claim 1 , wherein: the first insulating tape is attached to cover 1 mm to 2 mm of a coated portion of the first electrode which is coated with an active material. 4 . The rechargeable battery of claim 1 , wherein: the non-coated portion of the first electrode further includes a second insulating tape which is attached, along the first insulating tape, to a surface opposite to the surface to which the first insulating tape is attached. 5 . The rechargeable battery of claim 1 , wherein: a melting point of the first insulating tape is higher than a melting point of the separator. 6 . The rechargeable battery of claim 1 , wherein: the first insulating tape is made of any one of polyamide (PA), polyimide (PI), and ceramic. 7 . The rechargeable battery of claim 1 , wherein: a melting point of the first insulating tape is 200° C. or higher. 8 . The rechargeable battery of claim 1 , wherein: a winding end portion of the electrode assembly further includes a fixing tape which is attached to the non-coated portion of the first electrode.
