<p>Provided are a secondary battery and a battery module including a plurality of secondary batteries that are connected to one another. The secondary battery comprises an electrode assembly (10) having a first electrode (11), a second electrode (12), and a separator (13) interposed between the first and the second electrodes (11, 12), and a case (34) for mounting the electrode assembly (10) therein. A retainer (80, 180, 280, 380) is provided coupled to the electrode assembly (10) and enclosing an end of the electrode assembly (10). According to an embodiment of the present invention including the retainer, an electrode assembly is prevented from moving and electrical connection of the electrode assembly is stabilized, and thus durability and reliability of the electrode assembly is improved.</p> |
