Abstract
A lithium secondary battery includes: a lithium secondary cell including a surface parallel to an electrode surface, a single-body pressing structure configured to apply pressure to the surface of the lithium secondary cell, wherein the pressing structure is configured to contract and expand in response to a change of volume of the lithium secondary cell; and a housing that accommodates the lithium secondary cell and the pressing structure, wherein an area of a surface of the lithium secondary battery which is parallel to the electrode surface is less than an area of a surface of the lithium secondary battery which is orthogonal to the electrode surface.
