| 摘要 |
Lithium secondary batteries having deformation prevention straps for preventing the electrode assemblies of the lithium secondary batteries from deforming and methods for manufacturing the same are disclosed. A lithium secondary battery comprises an electrode assembly comprising a first electrode plate having a first electrode tab attached thereto, a second electrode plate having a second electrode tab attached thereto, and a separator between the first and second electrode plates. The electrode assembly is formed by winding the first and second electrode plates and the separator. A deformation prevention strap is attached to at least a portion of the electrode assembly and is wound in a direction substantially perpendicular to the direction in which the electrode assembly is wound. The electrode assembly, including the deformation prevention strap, is enclosed within a battery case. A cap assembly seals the case and comprises an electrode terminal electrically connected to the electrode assembly.
