    摘要： A cylindrical secondary battery including a can including a circular bottom part and a cylindrical side part having an opened one end, an electrode assembly in which a first electrode plate, a second electrode plate, and a separator are wound and which is accommodated in the can, and a collecting plate arranged in a direction toward the first electrode plate. The first electrode plate and the collecting plate, and the second electrode plate and the bottom part are electrically connected to each other in a non-welding manner. According to the embodiment, since the electrode assembly and the collecting plate and also the electrode assembly and the can are electrically connected to each other without the welding, the electrode assembly may be prevented or reduced from being damaged by foreign substances generated during the welding, thereby improving stability of the secondary battery.

    摘要： A secondary battery includes a cylindrical case; an electrode assembly accommodated in the case and including a first electrode plate, a second electrode plate, and a separator, the electrode assembly being wound such that the first electrode plate is arranged at an outermost side and is in contact with the case; a cap assembly coupled to the case and electrically connected to the second electrode plate; and a first swelling tape attached to an inner surface of the first electrode plate in a state in which the electrode assembly is wound, the first swelling tape having a multi-layer structure. The swelling tape may be applied to a base material finishing portion of the electrode assembly to improve quality distribution of the base material finishing structure due to long-diameter distribution. In addition, a swelling effect may be improved through the multi-layer swelling tape.

    摘要： One embodiment of the present invention relates to a cylindrical secondary battery. The present invention comprises: an electrode assembly comprising a negative electrode plate, a positive electrode plate, and a separator interposed between the negative electrode plate and the positive electrode plate, and having a wound shape in one direction; a metallic finishing tape attached to the outer peripheral surface of the electrode assembly so as to cover at least a portion of the electrode assembly; a cylindrical can having one side opened so as to accommodate the electrode assembly along with an electrolyte; and a cap assembly coupled to the open one side of the can so as to seal the can. According to the present invention, by applying the metallic tape to a winding finishing portion of the electrode assembly, the effect is gained of improving the dispersion of quality of a substrate finishing structure, caused by the dispersion of a major axis. In addition, the metallic tape plays the role of an additional end tab (substrate tab), and thus the effect is gained of improving the dispersion of cell performance.
