Patent ID: 11876166

Abstract:
An embodiment of the present invention provides a secondary battery capable of concurrently securing a vibration characteristic and an insulation function of an electrode assembly by using one finishing tape. To this end, a secondary battery according to an embodiment of the present invention may comprise: an electrode assembly including a first electrode plate, a second electrode plate, and a separator interposed between the first electrode plate and the second electrode plate; a can for receiving the electrode assembly; a cap assembly for sealing the can; a first current collection plate provided above the electrode assembly and electrically connected to the first electrode plate and the cap assembly, respectively; a second current collection plate provided under the electrode assembly and electrically connected to the second electrode plate and the can, respectively; and a finishing tape having a first region which has an adhesive layer formed thereat to surround the circumferential surface of the electrode assembly, and a second region which can surround a space beyond the upper end of the electrode assembly.
