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.
Claims12
A secondary battery comprising:
- a pouch case;
- an electrode assembly accommodated in the pouch case and including a first electrode plate, a second electrode plate, and a separator positioned between the first electrode plate and the second electrode plate;
- and
- a support plate which is coupled to and partially inserted into one end surface of the electrode assembly to support the electrode assembly where the first electrode plate, second electrode plate, and separator are exposed, the support plate comprising a base plate coupled to the electrode assembly, the base plate covering a lower end surface where the electrode assembly is exposed;
- and
- a rib upwardly extending from the base plate and inserted into the electrode assembly, the rib being electrically insulated from the first electrode plate and the second electrode plate,
- wherein a portion of a first end of the base plate and a portion of a second end of the base plate are respectively located at opposite lower ends of the electrode assembly.
