Abstract
Disclosed is a secondary battery comprising: an electrode assembly in which a first electrode plate, a second electrode plate, and a separator are rolled up; and a support plate which is coupled to one end surface of the electrode assembly where the rolled first electrode plate, second electrode plate, and separator are exposed, so as to support the electrode assembly. A secondary battery according to an embodiment of the present invention comprises a support plate coupled to the lower end of an electrode assembly, whereby, when the secondary battery falls, movements of the electrode assembly can be prevented, and deformation of the electrode assembly due to an external impact can be suppressed.
