Device, method and system for attatching secondery battery tape

A method for attaching a tape, comprising:

• disposing a cylindrical electrode assembly on a lower support structure;
• attaching a first region of an insulating tape to a side surface of the electrode assembly;
• bending, by a plurality of compression jigs, a second region of the insulating tape protruding in a height direction of the electrode assembly along a circumference of an upper surface of the electrode assembly, and attaching the insulating tape to the upper surface of the electrode assembly;
• and
• flattening, by a pressing device, the upper surface of the electrode assembly to which the insulating tape is attached.

A secondary battery comprising:

• a cylindrical electrode assembly;
• and
• an insulating tape attached to the electrode assembly by a tape attaching device comprising:
• a lower support structure configured to support the cylindrical electrode assembly;
• a plurality of compression jigs configured to bend the insulating tape attached to a side surface of the electrode assembly and protruding in a height direction along a circumference of an upper surface of the electrode assembly, and attach the insulating tape to the upper surface of the electrode assembly;
• a pressing device configured to flatten the upper surface of the electrode assembly to which the insulating tape is attached;
• and
• a controller configured to control the compression jigs and the pressing device.
