Abstract
A lithium secondary battery according to an embodiment of the present invention includes a stack structure including a plurality of pouch cells and an elastic foam layer formed on an outer surface of at least one of the plurality of pouch cells. A uniform pressure may be provided by the elastic foam layer to prevent deformation of the battery due to contraction and expansion of the electrode.
